Cisco GLC-SX-MMD 1000Base-SX SFP MMF Transceiver 850Nm/W DOM – New

The Cisco GLC-SX-MMD is a Gigabit Ethernet SFP (Small Form-factor Pluggable) transceiver designed for short-range multimode fibre (MMF) connectivity in enterprise and data centre environments. Operating at an 850nm wavelength, it supports reliable 1Gbps data transmission over distances of up to 550 metres, making it suitable for switch uplinks, access-layer interconnects, and core networking deployments.

This unit is new but supplied without original manufacturer packaging. It supports Digital Optical Monitoring (DOM), allowing real-time visibility into optical performance such as temperature, voltage, and transmit/receive power levels. The LC duplex interface and hot-swappable SFP form factor enable easy installation and maintenance in compatible Cisco networking equipment.
