There have been several questions involving the compatibility of various Mini GBIC SFP’s, like the glc sx mm 1000base sx, with internal networks. The most effective manner of choosing which SFP or GBIC transceiver you could implement when upgrading your current systems is to chart:
- What are you working with
- The type of switch you’re using
- Software that is currently installed for the routers. An example would be if you have Cisco’s GLC SX MM or GLC LH SM, you’ll probably be dealing with some version of their IOS (Internetwork Operating System), and
- What type of fiberoptic cable you’re using or is installed. There are two types of optic communication between switches, multi-mode and SM you’ll be working with either single-mode or multi-mode fiber. MM networkstypically travel small distances and are mainly used for networks below 550 m apart- although they can communicate further by using the proper SFP or GBIC transceiver. One of the most common MMtransceiver modules is Cisco’s GLC SX MM.
All components must be set up to work together. The software version you’ll need will depend on the type of platform you’re working on. As an example if you’re working on the Catalyst Express 500, you’ll need to at least have the 12.2(25)FY release of Cisco’s IOS. In order to work with this platform you’ll want to have a WS-CE500-24LC. In regards to the SFP or GBIC transceiver is concerned you could integrate a GLC SX MM or a GLC LH SM. These components will only work on multi-mode fiberoptic cable)
You might select to use the same manufacturer for your platform, Switch, transceiver, and software. (Just work with the manufacturers compatibility charts you’ll be fine). Now doing this will get pricey and if you’re working with a limited budget it may restrain your ability to upgrade your network. The other choice that many IT personnel are selecting is to use a well known brand for the platform and switch while selecting to use a OEM equivalent part for the SFP/GBIC. Due to IEEE. the manufacturer of the router and platform is required to preserve any guarantee and support even if an OSI Level 1 component such as the 1000base sx was not produced by them. This can oftencuts down the expense of upgrading your small form factor pluggable and giga-bit interface converter transceiver modules by 50% or more
