Cisco GLC-SX-MM 1000BASE-SX SFP Transceiver Module

I have purchased several of these SFP modules, some Cisco branded and some off brand. These (Cisco GLC-SX-MM) have been the most reliable and well worth the few extra $$. The work as expected with 62.5micron and 50micro MM Fiber.

We have several of these mini-GBICs in use on various Cisco 2960, 2960S, and 2970 models. They work just fine connecting to 62.5micron and 50micron multimode fiber. They're a little pricey (typical for Cisco parts), but I prefer to use the Cisco branded parts rather than risk incompatibility with a 3rd party device. I've had several of these SFPs running continuously for many years and have not detected any problems with any of them.
