Connting gbic and sfp

Hi,
I have two switches, 3750 (12 SFP ports) and 2950 (with 2 GBIC ports) and I want to connect the GBIC from 2950 and SFP from 3750 interfaces at gigabit speed. Are there special fiber patches for doing this (with one end for SFP and the other for GBIC)?
Thanks in advance

HI Gabriel,
Depending on the type of SFP you are using, you will need one of the following types of cables:
Single Mode LX LC-to-SC Connectors
Fiber Multimode SX LC-to-SC Connectors
The SFP uses an LC-terminated cable ....
Hope that helps - pls rate the post if it does.

Difference between GBIC and SFP module

when its best to use GBIC and When to use SFP ?
what i know is basically SFP is a smaller version of GBIC but I am not clear when to use what any special recommendation ?

GBIC - Datasheet definition:
The industry-standard Cisco Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. Cisco GBICs can be interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-CWDM interfaces on a port-by-port basis.

SFP - Datasheet definition:
The industry-standard CiscoÂ® Small Form-Factor Pluggable (SFP) Gigabit Interface Converter is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network (Figure 1). SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

Ok, now if you have a look at the above datasheets for GBIC's & SFP's, you would find that GBIC & SFP are different in there sizes, hence it is more of a question as to which gigabit solution your device supports. If your device supports GBIC, like 4500's, you will have to go for a GBIC, & if your device supports SFP, like 3750's, you will have to go for a SFP. These days all the latest devices would have SFP's normally.
Also, here is a very good document which lists almost all the GBIC's & SFP's & the devices on which they are supported, you may check your device on this list & decide which one can you use accordingly.
Hope that helps !!

GBIC AND SFP

Am a little bit confuse as to the differencen sfp and GBIC.
I have also come across gigabit Stack gbic. Any contribution to make this clear
will be appreciated.
Cheers
Jitez

SFP and GBIC are just interface units that makes the users having a better choice of what to be able to connect to an switch, instead of having a switch model for single mode fiber(LH,ZX) , multi mode fiber, copper, CWDM and so on... The make an switch that have the logical interface and then just make the physical interface connectible and interchangeable in the switch.. Thus only needed to make fewer models.
The difference between SFP and GBIC are primarily just an big size difference, it's really impossible to connect an GBIC to an SFP port and vice versa, so there is no worries about connecting the "wrong" interface unit.
The gigastack gbic are for making an connection that you could stack switches with and only use one GBIC port instead of two if you use ordinary Ethernet GBICs for it.
Hope this was to some help/assistance?

GBIC and SFP Module

HI , Welcome for All
I am putting two series widely in my new network , which are 500 and 3500 series , but here I am getting confused to select the Interface Module , Should I opt GLC-SX-MM or WS-G5484
Thanks
Praveen 9212 506 503

500 supports only GLC-SX-MM and GLC-LH-SM
GLC-SX-MM is SFP while WS-G5484 is GBIC they both operate in ordinary multimode fibre
You may opt to GLC-SX-MM for 500 and WS-G5484 for 3500. But you should tell us the exact model of you 3500.

GBIC to SFP

Can I connect a GBIC port to a SFP port ?are there suitable fiber cords for the same?

There are also some GBICs/SFPs that are designed to work on different frequencies than the standards.
CWDM does this and occasionally I find that people end up with one of one type, and the other side is another type.
Just take a look at their names and you can usually figure out what they are.
This page seems to be a good quick list of common GBICs and SFPs.

LMS 4.0 Inventory Collection GBICs and serial nos.

Hi All,
I have larger numbers of WS-C3560X-24/24P/48 Cisco switches with1000BaseSX SFP GIBCs installed per switch in my network and they are all added to my DCR just fine. However, when i generate an inventory hadrware report GBICs and GBICs serial number is not showing up. Is there any special settings i need to make?
Let me know if you need additional information to help to identify the problem, i'll provide it.
Any help will be very much appreciated. Thank you in advance!
Rob

GBICs and SFPs and such will show up in a detailed device report.
If you create a custom report ("Reports, Report Designer, Syslog and Inventory, Create"), you can extract that information into a useful form for your purposes. You will want to use the report designer and pull out "port serial number" plus something like device name. I just did this myself and verified it will pull the SFP serial number from a device. They key fields are "Inventory Group: port" and "Attribute: port serial number"
Here is a screen shot from the report I created showing the serial number you are asking about:

Cisco 4900M integrated X2 ports, CVR-X2-SFP10G and SFP-10G-SR

Hi,
We are going to order two(2) cisco 4900M switches for core and twelve (12) 2960S switches for access (4 stacks with 3 switches each), connected to the core with 10G MM optical paths (up to 300M each). In addition I have one gigabit half-card but it is not related to my questions here. Please see my attached diagram.
So my questions are:
1. Point 1.Can we use integrated eight X2 ports of every of the both 4900M switches as plugging into four of them four convertors CVR-X2-SFP10G and to plug on every of the convertors sfp tranceivers SFP-10G-SR - as it is described on the diagram, or I need for something more in addition to described? I found only some minimum soft releases to use as requirement to use these convertors and sfp tranceivers, but is there something additional I need?
Note:I'm asking that because Dynamic Conf Tool doesn't give me to do such configuration, actually these convertors and SFPs are missing there at all, but it sometimes happens with some products... In documentation it is described this should work (if I didn't pass something which is my main consern and why I'm asking here).
2.Point 3.If this shouldn't work, the other alternative (not described in my diagram) is to use X2-10GB-SR modules without any SFPs - just ot use SC connectors for the optical cables instead of LC. So my question in that case is will 10G links work between X2-10GB-SR at one side and SFP-10G-SR at the other side where I have 2960S switches and this is the only option? Is is expected to have some problems in that scenario?
Note:Actually if Point 1 is workable I prefer to use it instead of Point 2 because of minor price optimization when using SFPs with convertors in comparisson to X2-10GB-SR.
3. If the both variants are possible, which one is preffered and why, what advantages does it have (for example low latency of something else)?
Thank You in Advance
Asen

Just for your information, a fiber link does not care if one end of the fiber has an GBIC (SC-type connector) and the other end has a SFP (LC-type of connector); or any other transceiver footprint (X2, CFP, etc.).. The thing that is important is that each module is the same specification, and matches the fiber type and link length of the network (10GBASE-SX in this example).
Good luck.

GBIC or SFP Information

Can anyone please let me know that how will I find the availability of GBIC or SFP card in its slot provided.
I am trying to find this for following device types
6509, 7200, 7500, 7600 & 29-00 devices.
I tried
"show diag" it gives information only up to port adapter level, no information is provided about the availability of the pluggable factors.
"show interface GigabitEthernet" I see some response even if the hardware is not plugged in.
Please help

Hi,
For the 6500 and 7600 one command might give you the information needed:
show idprom interface gigx/y
or for the entire module:
show idprom module x
For the 7200/7500 platform I am not aware of any command.

How to show module and SFP information include hardware serial number on Nexus switch?

How to show module and SFP information include hardware serial number on Nexus switch? Thanks.

Hi,
The show inventory command will give you details of the Nexus chassis, power supplies, Supervisor, Fabric, I/O modules (including FEX if you have them) etc. To get the details of the installed SFP/SFP+ then you'll need to use the show interface transceiver command.

GBIC and Mini-GBIC?

Are they comparable?
If I have a switch that uses GBIC and I buy a new switch that uses mini-GBIC would they communicate with no ploblems?

EtherChannel Between Catalyst 3550/3560/3750 Series Switches and Catalyst Switches Running Cisco IOS System Software Configuration Example is a document that would show how they work together.
http://www.cisco.com/en/US/customer/tech/tk389/tk213/technologies_configuration_example09186a0080094647.shtml
Also, I can tell you that I have connected 3750 switches and 3560 switches with SFF to 6509 and 4507R that have GBICs with no problems.

Fiber Patch cord bewteen X2-10GB-SR and SFP-10G-SR

I would like to know which patch cord should I be using between X2-10GB-SR and SFP-10G-SR. The mention of part no would be very helpful.
Thank You

CSCO11584685 wrote:dude, double check before you answer.according to http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6974.htmlX2-10GB-SR has SC connector, and the SFP-10G-SR has LC connector. so that would require SC-LC connecitor with MMF, 850-nm wavelength.
Thanks Sulaiman for the correction. I should not have relied purely on memory as it has potential of failing :-).

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

Connect GBIC to SFP

Hello everybody.
Ok. here is the question. Is it possible to make an uplink between a Cisco Catalyst 3550 switch (via 1000BASE-T GBIC model WS-G5483) and a Catalyst 2960 switch (via 1000BASE-T model GLC-T SFP module or it's gigabit Etherner ports)?
Best Regards
Luis Alvarez

Hi , just tested it for you , yes it works , WS-C2960-24TT-L & ws-g5483 & WS-C3550-48-EMI connected together with the rj45 10/100/1000 port ,see logs attached :

I have to replace this router for a Cisco7206VXR (NPE-G2), the fiber will be connected to an SFP module.
The fiber size is approximately 15 meters and the specification is: 50/125
I will just rebuild the connectors on the fiber (replacing only my side), changing SC to LC.
(see the figure)
Thanks for help!

- Is there anything else I should observe?
