GLC-SX-MMD Description
Cisco GLC-SX-MMD is a 1000BASE-SX Gigabit Ethernet SFP transceiver designed for short-range multimode fiber applications. Operating at 850 nm, it supports transmission distances up to 220 m on legacy 62.5 µm FDDI-grade MMF, 550 m on standard OM2 fiber, and up to 1 km on laser-optimized OM3/OM4/OM5 fibers.This hot-swappable module features an LC duplex connector and provides Digital Optical Monitoring (DOM) for real-time link diagnostics. With its extended temperature rating (-5°C to 85°C), the GLC-SX-MMD offers robust performance for enterprise, campus, and data center environments.

This is where the fun begins. Plugging them in now. All lights green.
Fast… very fast. Good parts.
Standard multimode optic. We have thousands in production. Layer23 is a reliable source.
We verify the hologram on every unit. Yours are real.
Replaced a dead module. System back online. Thanks for the rush shipping.
