Cisco GLC-ZX-SM 1000Base-ZX 1550nm Single-Mode SFP (mini-GBIC) Transceiver

CISCO GENUINE. BRAND NEW. FACTORY SEALED. FULL CISCO WARRANTY. FROM CHICAGO COMPUTER SUPPLY

Overview

When your network needs true long-distance Gigabit Ethernet, standard optics will not reach far enough. The Cisco GLC-ZX-SM supports extended fiber spans, delivering reliable 1G 1000Base-ZX connectivity over single-mode fiber (SMF).

This SFP (mini-GBIC) transceiver operates at 1550nm and supports link distances up to 70 km, making it ideal for metro networks, long campus interconnects, and extended backbone links. It also remains flexible across Cisco platforms, as SFP modules can be mixed per port, letting you scale your network without redesigning the entire setup.

If you need a Cisco 1G ZX optic that delivers long-distance performance with stability, this module fits perfectly.
