                   Dear sir/ma,

what is the significant different between GLC-SX-MM and GLC-SX-MMD

i know these are transceivers and the first is EoL and the second is digital optical monitoring (DOM).

i need the significant difference between them.

Please provide white paper/documentation.

Hi Kuku,

As you said, both are transceivers but the MMD has some extended feature compared to MM. The below are the differences between these two types of transceivers.

GLC-SX-MM

1000BASE-SX SFP transceiver module for MMF, 850-nm wavelength, dual LC/PC connector

GLC-SX-MMD

1000BASE-SX SFP transceiver module for MMF, 850-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector

The MMD supports DOM whereas the MM doesn't suppor the same.

This URL will be useful for you. It contains the compatibility matrix and the IOS it supports.
