The Cisco GLC-T is a 1000BASE-T copper SFP (Small Form-Factor Pluggable) transceiver module designed for high-speed Gigabit Ethernet connectivity over standard Cat5e/Cat6 copper cabling. Engineered to Cisco's exacting standards, this transceiver delivers reliable, wire-speed 1Gbps performance over distances up to 100 meters — making it an ideal choice for enterprise LAN deployments, data center access layers, and network upgrades where copper infrastructure is already in place.
Every unit sold by WhaleyComm is thoroughly inspected and tested to factory specifications before shipment, ensuring you receive a product that performs exactly as intended right out of the box.
