Cisco GLC SX MM is a commonly used SFP transceiver that works with 850nm multimode fiber. Cisco GLC SX MM is designed to use in 1000Base-SX applications, it is with duplex LC interface and hot swappable, we supply the GLC SX MM Cisco equivalent SFP transceivers.

The GLC SX MM transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.The GLC SX MM transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.


The GLC SX MM SFP transceivers are high performance, cost effective modules supporting data-rate of 1.25Gbps and 550m transmission distance with MMF.
