Choosing correct optical patch cable based on SFP module

can someone share information regarding the topic (all cable parameters should pass to a certain SFP module: connector type; mode type; diameter etc)?

Ok, so you'll need a patch cord of the following specifications:
<LENGTH> - You choose whether you want pre-made 10 metres or you can get them to customize the length (will cost more, obviously).
Terminating end types - LC to LC (Duplex);
Multi-Mode optical fibre;
OM4 - You can use OM3 if you want but I'd rather use OM4. Don't even attempt to try OM1 or OM2.
<COLOR>- Your choice. Normally, OM4 is aqua but you can choose any color you want (may cost more). DO NOT USE YELLOW as this means a different type of cable (single-mode). You do not want to make your fibre optic cabling confusing for everyone.
NOTE: If someone wants to sell you an "angle cut" multi-mode fibre, they need to be taken out and shot.

Cisco 2960S-24TS-S using SFP modules between switches

I am using Cisco 2960S-24TS-S using SFP modules for two different speed requirements, I have two SFP ports using 100Mbit modules and the other two SFP ports using 1000Mbit modules.
I have two Cisco 2960S-24TS-S switches connected together via a fiber optic cable, and each SFP module is on port 28, with a 1000 Mbit SFP module in each, and the two switches will not connect. The fiber was checked with a light tester not a db kit.
Do I need to have SFP port specific setup details in a configuration file for the Cisco Switch or does the SFP module handle this?
" interface GigabitEthernet1/0/28" - set up in config file for the port. Does this need to dictate "interface 100" or "1000MbitEthernet1/0/28" instead?

The ports should auto-negotiate speed you should not need to hard code them to get them to come up , Are the ports showing up/down or down/down can you post the show interface for each side and the show run int x/x for each port

GBIC SFP Module

Hi,
i have got GLC-SX-MM 1000Base-SX SFP Fiber Module, so is it 10/100/1000 Mbps or just 1000 Mbps?

Hi Anand,
It is just 1000 MBPS.
And AFAIK all the 1000 Base SX GBIC modules only operate at 1000 MBPS and if any gbic module is supposed to support 10/100/100 it is not fiber it should be a RJ45 Base module having UTP5 cable and not fiber cable.
Copper SFP modules can operate at 10, 100, or 1000 Mbps on some Cisco devices. To find the supported speeds for the
Have a look at this
http://www.cisco.com/en/US/products/hw/modules/ps5455/prod_installation_guide09186a00803aa0da.html
I am not able to reacall right now if there is any fiber module which operte at 10/100/1000.
HTH , if yes please rate the post

SFP and Mode Conditioning Patch Cable

Is it safe to assume any SFP designed for single mode fiber (i.e., MGBLH1) can work with multi-mode fiber if using a mode conditioning patch cable?

It should work. The "mode conditioner" adds a loss in your optical link, typically 2 db.
If you want be sure you must do a link budget.

Linking C2960s switches through Fiber optic patch panel.

Hi, I have C2960s switches. I have to interconnect the switches through Fiber optic patch panel. Let me know which is the type of the connector used in the SFP ports.

There are a types of connectors that you need to consider:
1. Switch to Fiber Patch Panel
2. Fiber patch panel to Fiber patch panel
However, typically SFPs have LC type connection. With regards to Fiber Patch panel, typically (in my experience) SC type connection is used.
I have attached screenshots of the connectors as well :)
Don't forget to rate or mark as correct! :)

Optical Fiber connection between GBIC module and SFP module

Hi
I am in need of help.
I have a 3750 24TS-S, 2 port SFP, switch at the edge. And i have a 4507R switch at the Distribution layer. In 4507 switch I have WS-X4515 Sup IV supervisor engine with 2 GBIC Port and also have WS-4306-GB 6 port GBIC module. I am using WS-G5486 Single mode connector, LX/LH tranceiver to connect to this port.
This is the scenario.. i want to know is it posible to conect one end of the fiber cable to connect to a SFP Module ( 3750-24TS-S, 2 Port SFP) and other end ( WS-X4515 Sup IV supervisor engine with 2 GBIC Port or WS-4306-GB 6 port GBIC module) at the WS-G5486 Single mode LX/LH connector ?????
Plz let me now asap.. i need to give a solution imdtly.
Thanks & regards
Jacob

Discussion is never a problem ....;-}
The issue is that the signal is "too loud" and is distorted (or, more correctly, is so loud it overloads the receiver).
The operational envelope for nearly every receiver of any kind includes a bottom number (too weak to hear) and a top number (too loud to understand).
As an example, think about an system where you have a hearing aid that would let you hear someone speaking in a normal voice from 100 feet away ... then having someone scream the same words into the hearing aid from 6 inches away ... the sound would be distorted and you would have difficulty understanding them ... after a while, you'd begein to go deaf and eventually, it would sound normal (until you became completely deaf).
So, what you need to do is look at the transmitter power, and the envelope/range of acceptable power the receiver can hear.
Normally that difference is the optical budget ... given the loss numbers of the media between the two, you can determine if you have enough power to make the trip.
In a Lab environment, you still have to hit the receiver's budget number, but from the other end (the "too high" side).
If you know the transmitter puts out X, and the receiver can accept from Y to (X-50), then you need to add enough attenuation to get X down to (X-50)or lower (but still more than Y).
When you have a transmitter powerful enough to drive tens of kilometers, putting one two meters away from the receiver will pretty much guarantee a burnout (unless you install optical attenuation).
Good Luck

10Gb fiber cable with 1Gb SFP

Hello,
I have 10Gb fiber cable that we do not need, I was curious to know if I could use a 1Gb SFP module instead of 10GB module?
We do not want to have to pull new fiber, or pay for an additional 10Gb module if we do not have to.
Thanks,
Chad

Cables (or other layer 1 media) don't have a speed. Cables have physical properties (singlemode, multimode, length, termination type etc.) that make them generally suitable for certain applications (1 Gbps Ethernet, 10 Gbps Ethernet etc.).
Both 1 Gbps Ethernet and 10 Gbps Ethernet can operate over multimode and singlemode cabling, given the right transceivers and optical properties.
Tell us what kind of cable and transceiver and we can answer your original question better.

How to make my computer send all the audio through optical audio cable instead of headphone jack?

Howdy,
To listen to online radios or CD's played from my computer, I used to connect the computer to my home entertainment system from the computer's headphone jack to the AUX port on my home entertainment system.
I now wanted to get better sound and purchased the optical audio cable. However, I don't know how to tell my computer to send the audio signal to the home entertainmeny system through the optical digital cable rather than through the headphone jack. If I just unplug the cable connecting the headphone jack and the AUX port and only have the PC and the system connected with the optical audio cable, I don't hear any sounds. I suspect the computer isn't sending any data through the optical audio port. I'm not able to find how I can adjust the settings on my computer so that from now all sounds are output through the optical audio.
1) I'd like to do that mainly for my HP desktop (configuration below) and any advice on how to do that would be appreciated.
2) I also have a HP laptop (configuration below) and was wondering if that would be doable too (even though it doesn't appear to have a audio out, but it has HDMI out - can one convert it to optical audio?
Thanks in advance!

Hello @_goma,
Welcome to the HP Forums, I hope you enjoy your experience!
I have read your post on how you are looking to make your computer send all the audio through an optical audio cable instead of the headphone jack, and I would be happy to assist you in this matter!
To configure your desktop to enable the optical audio cable, I recommend following the steps below:
Step 1. Click the Windows Key Button on your desktop
Step 2. Type "Control Panel"
Step 3. Select "Control Panel" in the top right-hand corner
Step 4. Select Sound
Step 5. Under the Playback tab, right-click the white area below the devices available
Step 6. Select "Show Disabled" and "Show Disconnected Devices"
Step 7. Connect your Optical Audio Cable
Step 8. Select your Optical Audio Cable as the default device and click "Enable"
Since it is not possible to convert the HDMI out to audio out on your notebook computer, it is unfortunate that the notebook is not able to connect with an optical audio cord.
Please re-post with the results of your troubleshooting, and I look forward to your reply!

Ethernet Patch Cable from One iMac to AirPort Extreme Please help!

Hi, I have an iMac on one side of my home office, and a cable modem connected to my AirPort Extreme. I just bought a 25 ft. patch cable to run and connect to the router for faster speeds, but it is not working. I tried connecting it to the AirPort and the modem, and I did not get a light on the AirPort extreme or on the modem (I have disabled the wireless functionality on the gateway so it is just a modem now). I noticed that the cable has metal on the sides of the plug. Does that mean anything? How can I connect this and get it working properly?
Please help me!

your post is a little confusing
your imac is on one side of your home, and both your cable modem and extreme are on the other side of the house?
temporarily move the imac to the same side and try a different cable, seems like a cable issue

Cannot get 5.1 Surround Sound with optic fiber cable (Mini Toslink)

I have a Macbook Pro (Early 2011 Model) and after spending lot of time I figured out that the best way to get 5.1 surround sound output is to connect the MBP to the AV Receiver with the optic fiber cable (Via Mini Toslink Adapter). So after reading all the articles and forums on it, I went and purchased the cable and adapter and hooked up my MBP to my AVR 142 Harman / Kardon receiver.
But now I’m still not able to not get Digital 5.1 surround sound!! Additionally, in Audio MIDI Setup (under Utilities), I can only select Stereo from the drop down menu, as "5.1 Surround" and every other option, such as 7.1 surround are grayed out.
Is there anything that I have missed out in the setup? or do I have to try some other method to get the surround sound??
Please Help!!

ATV definitely supports AC3 DD 5.1... etc, but definately not through AirPlay, only streamed through the inet.
I also found, in the case of Netflix, that the AC3 is preserved in the highest bandwidth mode but not available in the lowest. (frankly i did not test the intermediate bandwidth)
I was quite pleased with the sound and picture from Netflix.
I am not so patiently waiting for AirPlay to support AC3 DD or DDPlus because I record my home video in %.1 surround (AVCHD) and can preserve it through Final Cut Pro and DVD or Red Laser, but cannot use the intended cable replacement (AirPlay) to play them.
Bummer..
I think/hope if more people request surround sound via AirPlay Apple may then follow through on this otherwise good idea.
FWIW

What optical audio cable to use with Mac Mini (late 2009) to receiver?

I want to do the following (removing TiVo for something else is NOT an option, EVER):
1) I want to watch TV through my HD TiVo (better than sex, better than chocolate, better than sex, chocolate, and anything else you can combine together).
2) I want to watch DVDs plus iTunes videos plus listen to iTunes audio through my Mac Mini.
3) I want to have digital optical audio (TOS?) 5.1 dolby for both
On the Mac Mini it says it has digital audio out. Isn't that the same thing as digital Optical audio out?

You need a regular optical digital cable, often called a Toslink, with a 3.5 mm miniplug adapter on the Mac mini end. The port is a combo port. When you insert the optical cable's miniplug into the port, because it is a tiny bit longer than a regular 3.5 mm miniplug, it activates the digital audio. Usually the port's output is analog by default.

Optical audio cable for iMac?

I need to find an optical audio cable for my 20" intel iMac.
I have not been able to determine what kind of cable that it is that I need to be able to hook up my iMac to my logitech z-5500's. I know that the z-5500's have an optical input on them, but it is a standard size optical input.
Does anyone know what exactly it is that I am looking for?
Any help is appreciated.

I wish Apple would sell a nice white Toslink ->Mini-tos adapter, as all of their products seem to be using the connector. (Or better yet, include it with the computers.)
The cable mentioned above will work fine and is not viciously overpriced like the Monster stuff. Another good quality solution, especially if you already have a regular optical cable, is this adaptor: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=180-968
I use two of those (both with Dayton Audio optical cables from the same seller, though any optical cable will do as there's no real difference between any of them) with my iMac and AirPort Express, and have not had any problems.

Optical Audio Cable Troubles

I recently purchased the the Panasonic G20 50" HDTV and the Panasonic blu-ray/reciever combo with surrond sound. I have the TV connected to the blu-ray player via the HDMI AV, I was told that I needed an optical audio cable to get surround sound from cable (Charter). When i try to connect the optical cable, I can't get a connection as in the cable can literally fall out and there is not a "snap" when I try to insert the cable. Can anyone tell me what I am doing wrong?
oh by the way its not the $10 cable, they are monster cables.

My two thoughts are:
1) You're inserting the cable in the wrong orientation and it's not going all the way in
2) The optical connector on the device in question is damaged/defective/loose. Which device is the cable falling out of? The surround receiver, the cable box, or both?
Personally, I'd recommend not wasting your money on Monster ever again by the way. I've seen $4 TOSLINK cables that do just as well as the Monsters.
