Cisco GLC-ZX-SM 1000BASE-ZX SFP Module 1550nm 80km SMF LC DOM GLCZXSM

Description:

The Cisco GLC-ZX-SM 1000BASE-ZX SFP Module is a Gigabit Ethernet small form-factor pluggable transceiver designed to provide long-distance fiber optic connectivity for enterprise and service provider network infrastructures. It operates at a wavelength of 1550 nm and supports data transmission over single-mode fiber up to 80 kilometers using LC connectors with Digital Optical Monitoring (DOM) capability for performance monitoring. Commonly installed in Cisco switches, routers, and network devices deployed in campus networks, data centers, and telecom infrastructures, this module enables high-speed long-distance network connectivity. Network administrators, IT engineers, and system integrators use this transceiver for fiber uplink deployment, network expansion, and replacement of existing SFP optical modules.

Applications:

The Cisco GLC-ZX-SM SFP module is used in enterprise and telecommunications networking environments requiring long-range Gigabit Ethernet connectivity over single-mode fiber. It supports high-speed data transmission between switches, routers, and network infrastructure devices across large campuses, metropolitan networks, and service provider backbones. Typical deployments include data center interconnections, campus backbone links, telecom infrastructure networks, and long-distance fiber communication systems where reliable optical network connectivity is required.
