Cisco GLC-SX-MMD-RF SFP transceiver, 1 Gbit/s, 850 nm, LC, multimódový, refurbished

The Cisco GLC-SX-MMD-RF is a high-performance, refurbished SFP (Small Form-Factor Pluggable) transceiver module designed for Gigabit Ethernet applications. It operates at a wavelength of 850 nm over multimode fiber (MMF), providing reliable and cost-effective connectivity for enterprise networks. This module supports data rates up to 1 Gbps and is compliant with IEEE 802.3z and SFP MSA standards, ensuring interoperability with a wide range of Cisco networking equipment.

Advantages

This refurbished transceiver offers the same performance and reliability as new modules at a reduced cost, making it an ideal choice for budget-conscious deployments. With Digital Optical Monitoring (DOM) support, network administrators can monitor real-time parameters such as optical power and temperature, enhancing network management and troubleshooting. The hot-swappable design allows for easy installation and replacement without disrupting network operations.
