Hi Cisco community,

I would like to ask if the Transceiver GLC-SX-MMD class1 21cfr is compatible for both fiber optic OS1 & OS2?

i can't find the compatibility in the internet. 

Cheers!,

OS = Optical, SINGLE MODE.
GLC-SX-MM is not compatible to OS1/OS2.

GLC-SX-MM is compatible with Multimode fiber cable,
if you want the model that is compatible with Single mode OS1/OS2 use GLC-LH-SMD
