Cisco 1G Multimode SFP Transceiver Modules, GLC-SX-MMD

Cisco 1G Multimode SFP Transceiver Modules 

The Cisco GLC-SX-MMD is a 1G Multimode SFP (Small Form-factor Pluggable) transceiver module designed to provide reliable Gigabit Ethernet connectivity over multimode fiber cables. Operating at a wavelength of 850nm, it delivers high-speed data transfer at up to 1 Gbps over distances of up to 550 meters with OM3 multimode fiber, and up to 220 meters with OM2 fiber. This makes it an ideal solution for enterprise networks requiring reliable, high-performance connections over shorter to medium distances.

The module features LC duplex connectors for easy installation and is powered by a VCSEL (Vertical Cavity Surface Emitting Laser) transmitter and a PIN photodiode receiver, ensuring efficient and stable data transmission. With a low power consumption of <1W, the GLC-SX-MMD is an energy-efficient solution for Gigabit Ethernet applications.

Compliant with the IEEE 802.3z standard for Gigabit Ethernet and SFF-8472 for SFP modules, this transceiver is highly compatible with Cisco switches, routers, and other networking equipment supporting SFP ports. Its hot-swappable design means it can be installed or replaced without disrupting service, ensuring minimal network downtime.
