What is a strand of fiber?

Hi all. I've heard this term (strands of fiber) used loosely. Is this referring to real clear glass on the middle of the fiber? In an example where you have fiber LC connectors on both ends with two connection devices. That would be equal to 2 wires?

Once again, Im new to fiber and try to get a good understanding of the concepts. Thank you

Yes, your definition is correct.

When people talk about fiber, it is difficult to know if they are referring to the cable or fibers in the cable.  Using the end of strands of fiber makes it pretty clear that they discuss fiber optics of actual glass inside the sheath of the cable.

If you want to learn some of the basics of fiber optics, take a look at the following Web site.  It can be a great reference source for understandable fiber, information of...

Good luck!

  • Can I connect SFP GLC-LH-SMD connector lc single fiber on Cisco 897VA Module?

    Hi all

    Please can I connect SFP GLC-LH-SMD connector lc single fiber on Cisco 897VA Module?

    Thanks in advance.

    If you have only a single glass fiber then the GLC-LH-SMD = is NOT good

    because it is for double connection to a pair of fiber.

    You would like more information by your ISP, you will most likely need a GLC-BX-D (RX-TX/1310 nm, 1490 nm) or a GLC-BX-U(1310-nm TX/1490-nm RX)

    See below

    1000Base-BX10-D and 1000BASE-BX10-U SFP for bidirectional single fiber Applications

    SFP 1000BASE-BX-D and 1000BASE-BX-U, compatible with the IEEE 802.3Ah standard 1000BASE-BX10-D and 1000BASE-BX10-U, carried on in a single strand of SMF standard.

    A 1000BASE-BX10-D device is always connected to a device of 1000BASE-BX10-U with one strand of SMF standard with functioning of the chain of transmission, up to 10 km.

    The communication on a single strand of fiber is achieved by separating the wavelength of transmission of both devices, as shown in Figure 2: 1000BASE-BX10-D transmits a channel 1490 nm and receives a signal of 1310 nm, while 1000BASE-BX10-U transmits at 1310 nm wavelength and a signal of 1490 nm. As shown, the presence of a separator of multiplexing (WDM) length of wave-division integrated with SFP to split the 1310 nm, 1490 nm light railways.

    Figure 4.      Two-way transmission of a single strand of SMF

    GLC-BX-D and SFP GLC-BX-U supports also digital Optics (DOM) of the functions of surveillance in accordance with approval of the standard of the industry (MSA) multisource SFF-8472. This feature gives the end user the ability to analyze parameters in real time of the FPS, such as the optical output power, optical input power, temperature, laser bias current and transceiver supply voltage.

  • 100BASE-BX10-U or GLC - FE - 100 LX - RGD?

    Hi all.

    I have AIR-LAP1522, and I need to connect via fiber. Documentation has said, I should use side 1522

    100BASE-BX10-U module. As I know it is a module to ports in 100 MB, wavelength of 1310 nm TX/1550 nm RX, 10 km on SMF monocatenaire.

    My question is, can I use GLC - FE - 100 LX - RGD (GLC - FE - 100LX) 100BASE-BX10-you and use the pair of SMF?

    I have FO single mode.

    And second question is: where is a diiference between GLC - FE - 100 LX - RGD and GLC - FE - 100LX?

    Best regards, Marcin

    The transceiver (GLC - FE - 100 LX - RGD) robust must be comaptible as long as you have two strands (duplex fiber).

    I recommend using the no robust transceiver (GLC - FE - 100 LX), the difference is the nominal operating temparature. There

    0 to 70 ° C (32 to 158 ° F) for commercial transceivers, non-robuste and -40 to 85 ° C (-40 to 185 ° F) for industrial (RGD) types. Data sheetof the reference.

  • Interconnect two SG500 base MGBBX1 or GLC-BX-D?

    Hello

    I want to connect two switches SG500 over a distance of 150 meters. I really need a MGBBX1 on one end and a GLC-BX-D on the other end?

    Sounds wiered for me... Why is this?

    Kind regards

    Klaas.

    http://www.Cisco.com/en/us/docs/interfaces_modules/csbna/MGB/Quick_Start/guide/Optical_Module_QSG_en-us.PDF

    Hello

    ----

    For the Cisco MGBBX1, use the Cisco GLC-BX-D as the

    SFP downstream. For the MFEBX1 of Cisco use Cisco GLC - FE-

    100BX-D as SFP downstream. The Cisco MGBBX1 and the

    Cisco MFEBBX1 only supported upstream

    -------

    Since you are using a single strand of fiber, you have a different wavelength to send in each direction.

    One side transmits using the 1490 nm wavelength, and the other side is transmitting on the wavelength of 1310 nm (and the reception on the 1490nm).

    The MGBBX1 only supports the upstream - U version AFAIK. Side acccess to the central part of the network.

    In the kernel, you need the other version, so there is no MGBBX1 SKU for this version.

    If possible, on 150 m, you should consider Multimode with 2 wires and MGBSX1

    1000Base-BX10 is capable of up to 10 km on a single strand of fiber.

    hope that helps

    Hello

    To bookmark this site.  He may have more information for you. Wikipedia

    Joining lengths of optical fiber is more complex than to join the electric wire or cable. The ends of the fibers must be carefully cleavedand then spliced, either mechanically or by merging with heat. Fiber optic connectors for removable connections are also available.

  • What is neg 30 "error on the optical fiber

    Hi all

    at our office, we have telco tec came and it has tested the demarc to our device fiber and reported this

    30 "error neg, he told us to check our equipment.

    My question is what is neg 30 "error. He told us that there is extremely low loss.

    When we do the ping of our device on teclo circuit, we see packet loss.

    Thank you

    Mahesh

    You don't have not provided us any information about the network or hardware you use or where this neg. 30 error is reported.

    My guess is the technician tested at the level of light at your equipment and measured - 30dBmv.  Most of the optical transceivers, GBIC/SFP, have a minimum level of optical input of-17 and - 29dBmv, according to the type (SX, LX, ZX, WDM).  So,-30dB receive level would cause errors on your link.

    Check the routing of the fiber to see if there are sharp turns or the kinks.  Additionally, make sure that the connectors are clean.

    Tell us what you find.

  • What tool would you use to create optical fiber cables?

    I created which, I hope, will be appropriate brushes to create what must be an accurate picture of vector of optical fiber.

    My question is, what steps you would use to make realistic fiber in adobe illustrator cc 2015?

    I tried the tool brush and pen. However, I found cutting an ellipse in half and using her own path is a good source.

    Thank you

    So two thoughts here. According to Visual processing, there are many approaches to making it. However, here are two things of Foundation that I consider important for you after your Visual processing is established.

    1. create the appearance you want. Below you can see I used a single path with several properties top STROKE in the appearance Panel. Press the button Add race in the pane appearance with this selected path and modify each stroke to get the look you want. Here I use 3 stroke properties. One is black and thick, the second is more thin and grey, and the last is a gradient on an attack of apoplexy that reflects the gradient on the path. Once you have created, select it and press the new button in the Panel of graphic Style. When you draw something, now click that graphic Style and it will make it the path for you.

    2. create an Art Brush with scale between the guides. In this way he traces a path with the art brush and always finish by the fibers of the end of your thread unaffected. Draw your image and drag it in the Panel forms. Choose Art Brush as the type, and then click OK.

    When the following options come up, then opted to evolve between the guides and drag the guide so you flush the part you want to not scale or adjust.

    Now, whenever you draw a path, choose this brush in the brush Panel and it will automatically draw with the part between the guides and add the endpoint without scales or distorted.

    Good luck

  • Server files to fiber without Xsan?

    Hi all

    We did a Mac Mini server for a long time now on ethernet on our small business network, and we recently replaced one of our editing Mac Pro (2010 model) with a more recent 2013 videos.

    The Mac Pro 2010 has a fiber inside, and I wonder if it is possible to use it to replace our server Mac Mini (El Cap) and run as a file on the network server using fibers. Our firewall is a Sonicwall NSA 4600, which has the ability to take entry fiber connections, then all customers would be connected via ethernet. All our data would be on the internal SSD drives, and configure a RAID is not necessary (there are already solutions secondary and backup in place).

    I have little or no experience using fiber (a company from the outside set up our private network edition). Before I jump into the rabbit hole, which was wondering is) adding a fiber to a network machine works similar to ethernet (i.e. just setting IP, Sub, etc.)? (B) what I need to set up an XSAN system with controllers separate metadata etc., or can I simply connect the mac pro in the switch firewall and SMB/AFP share as he was connected by ethernet? And (C) can other services OS X Server as a VPN server, RADIUS, or OD work through the fiber connection, or do I need to run an Ethernet line separate to those of work (or even to keep the Mac Mini for these functions)?

    The advantage that I would hope to achieve is a debit to transfer files to and from customers.

    Thank you!

    There are two types of use of fiber that your current Mac Pro could use.

    1. Ethernet over fiber - used for the connection of normal computer network
    2. FDDI over fiber - used for the connection of SAN storage

    It's not not obvious from your post that you are using. Ethernet over fiber option is mainly for going the distance, but could also be used with a faster for example 10 Gbit/s network connection.

    Your current Mac Pro run Xsan? If it means that he uses FDDI.

    Note: Everything needs to use compatible versions for Xsan for work.

    You can get the two 10 Gbps, that interfaces Ethernet fiber and FDDI interfaces for use with a Mac, this is done with a direct Thunderbolt adapter, or a bolt of lightning to box PCIe in which you want to keep a PCIe card - most likely even the currently in your Mac Pro.

    FDDI is only used for storage connections and is normally only used by servers. (And the storage itself.) It permanently unusable for normal networking, servers would also have Ethernet connections for this.

    A 'SAN' allows several servers share a single storage via direct connections (FDDI) device, normally only one computer can be connected to a storage device. The Xsan software or a similar software for other platforms acts as a controller to ensure these several servers can use the same storage without conflict.

  • Best WiFi for the internet fiber?

    We are switching internet providers of Charter, which is slow and unreliable, a fiber of 1 gig of TDS connection. Currently, we are using the modem provided by Charter (which we will return), combined with a very old AirPort Extreme of probably around 2007 and a just as old AirPort Express to extend the network, although I do not know if it is. We use an iMac connected to the internet 2010, but most of our consumption is on our iPad and iPhone, as well as the video streaming (Netflix, Plex, etc.). Due to the age and the layout of our House, it is not very easy to hard wire on television, thinking it is something that we watched in the future when we are ready for some changes.

    The fiber will be installed and connected directly to the iMac, but for iPads and TV streaming, I would try to put in place the faster WiFi network, I can. What would you recommend for this? A new AirPort Extreme would be the fastest option to work with the new fiber? Or are there routers WiFi non - Apple that would work better and are not too difficult to implement?

    With regard to the performance of the network that he will come down to will be the following:

    1. For broadcast on the Internet, you want a router that has a capacity of excellent data WAN - LAN throughput.
    2. You want a wireless system that provides the band total bandwidth of the best & possible rate for your home.

    For the first article, I suggest that you examine various models to see which offer best WAN - LAN throughput. An easy way to do is to check the links of graphics of router and switch router in the following SmallNetBuilder site.

    For diagrams of router, I suggest you choose the 'WAN to LAN flow"to the point of reference and then select FILTER for a list of routers of better performance at worst. When I did it just, it assessed the Netgear Nighthawk with a value of LAN 931,4 Mbps Wan. No consumer today router will provide 1 Gbps, but 931.4 is very close. By the way, the last (on the design of 2 years) AirPort Extreme 802.11ac just came out with only 325,5 Mbps.

    On the second point, you will need to look at some benchmarks:

    • 2.4 GHz UpDown flow
    • 5 GHz UpDown flow

    You may have installed ad-injecting malicious software ("adware").

    Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. You have already seen that it does not work.

    Save all data first.

    If you are not already running the latest version of Mac OS X, update or upgrade in the App Store you risk adware remove automatically. If you are already using the latest version, please log off or restart the computer. Still, some types of malware will be deleted, not all. There is no such thing as the automatic removal of all possible malware, either by OS X third party software. That's why you can't rely on software to protect you.

    If the malware is deleted in your case, you will still need to make changes to the way you use your computer to protect you from new attacks. Ask if you need advice.

    If the malware is not removed automatically, see below.

    This simple procedure to detect any type of adware that I know. Disabling is a procedure distinct and better still.

    Some legitimate software is funded by advertising and may display advertisements in its own windows or in a web browser while it is running. It's not malware and it may not appear. In addition, some Web sites display advertising intrusive popup that can be confused with adware.

    If none of your web browsers work well enough to carry out these instructions, restart the computer in safe mode. The malware will be disabled temporarily.

    Step 1

    Please triple - click on the line below on this page to select it, and then copy the text to the Clipboard by pressing Control-C key combination:

    ~/Library/LaunchAgents

    In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + v press return. Open a folder named "LaunchAgents", or you will get a notice stating that the file cannot be found. If the file is not found, proceed to the next step.

    If the folder opens, press the combination of keys command-2 to select the display of the list, if it is not already selected. Please don't skip this step.

    There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. If necessary, enlarge the window so that all the content show.

    Follow the instructions in this support article under the heading "take a screenshot of a window." An image file with a name starting in 'Screenshot' should be saved to the desktop. Open the capture screen and make sure it is readable. If this isn't the case, capture a small part of the screen indicating that what needs to be shown.

    Start a reply to this message. Drag the image file in the editing window downloading. Alternatively, you can include text in the response.

    Leave the case open for now.

    Step 2

    Do as in step 1 with this line:

    /Library/LaunchAgents

    The record which can open up will have the same name but is not the same as in step 1. In this step, the folder does not exist.

    Step 3

    Repeat with this line:

    /Library/LaunchDaemons

    This time the file will be called "LaunchDaemons."

    Step 4

    Open Safari preferences window and select the tab 'Extensions'. If the extensions are listed, post a screenshot. If there are no extensions, or if you cannot launch Safari, skip this step.

    Step 5

    If you use Firefox or Chrome browser, open the list of extensions and do as in step 4.

  • Java7 and Java6 won't work opening pogo games on firefox, but works perfectly for IE, what can I do to fix this?

    Java will not work on the computer all of a sudden. Now, when I go to open games Pogo room I get a red lego piece of Mozilla in the corner saying "plug ins have been disabled for your safety, the area will be"Java (TM) platform SE 6 U". I removed Java7 and reloaded, after it works not found Java6 and loaded and reloaded it and it does not work.

    Now after 3 minutes of the room does not not Pogo will give me the error message of

    Java not found or not working not

    Explanation:
    This error means Java (one of the technologies built into most browsers) does not work on your browser.

    You must have Java installed on your computer in order to run games Pogo, and it should work properly. Either you do not have Java installed, or the Web browser that you use currently does not support Java, or you have Java (or Javascript) disabled in your browser.

    How to solve the problem:
    Java is a free download that is needed to play Pogo games. Not all computers come with Java pre-installed.

    If you haven't played Pogo games before and get this error, you should probably just install Java on your computer.
    Click here for instructions on the installation of Java for your operating system and your browser.

    If you believe that Java can be installed but disabled in your browser, please make sure to activate the plugin for your browser. If you need help, click here.

    If you already have Java installed, and it is not disabled, your Java may be obsolete or not is more functional. In this case, your Java may need to be upgraded or reinstalled. If you need help, click here.

    I did click here in the last sentence, and all he wants me to is download Java7 which was the first reason, it did not work.

    I hope I explained it well enough, Mozilla, this is what I get, BUT if I go to Internet Explorer (which I HATE) the Java6 and Java7 work perfectly well. So, apparently, that the Java is downloaded correctly I just can't allow him to play very well with Mozilla and this is my main objective.

    Help EA games page went through with me and have proven time and again (after the 1 hour sessions, 45 waits for them) Java work on my computer perfectly with IE but not on Firefox and with the situation in rural areas, I became dependent on Mozilla because of the no optical fiber here it was my best and only source successfully using the internet here in the part far outside the country.

    Oracle has released a Java 7 11 update to fix security vulnerabilities and you should upgrade to this version.

    You use 3.82 GB to 4 GB of your memory. Something is to take all this memory, causing your computer slow down and eventually freeze. To see which uses the most memory, open the activity monitor by searching for it in the spotlight. Select the memory tab, and then click memory for sorting by the user higher at the lowest. What is at the top should not be more than 600 unless you use some videos crazy editing/rendering programs. You can 'leave' a process of this window if it takes a lot of memory. If you leave something, you will lose everything you were doing in the process (e.g. Word, Safari, etc...) Google Chrome is one of the largest memory there suckers. I don't know if you're using Chrome or not, but I give you just a heads up.

    If you see multiple instances of Adware, remove them.

    By default, there is nothing in the files of demons of the Agents/launch of launch system, so you can remove these items without damaging the computer. If you have an application that requires files to be placed in one of these files, it will add it in the folder. If you decide to remove items from these folders, what I would do myself, you will have to restart the computer to empty the trash.

    With regard to the login items, this launch when your username is connected. This means that it starts running as soon as you connect to your user account. Things like Spotify can use a lot of memory, even if you do not use it. If you don't want Spotify to open when you turn on your computer and connect, open system preferences > users and groups > Login Items > select the ones that you don't want and click on the. This does not remove it from your computer, just prevents it to launch at startup upward.

    Finally, there are user Agents throw that you probably shouldn't, particularly those associated with Mac cleaners and torrents. Again, you can delete everything in this folder safely. I suggest you to remove clean my Mac if it is in your Applications folder. Mac do not need antivirus software and most of the "free" antivirus software will tell you there are viruses even when there aren't any. They want you to think that get infected if you buy their product to "clean" what was never there.

    Good luck
