Cisco GLC-FE-100BX-U 100BASE-BX10 SFP Transceiver Module

BRAND NEW WITH FULL CISCO WARRANTY!!!

The Cisco GLC-FE-100BX-U is a Fast Ethernet (100 Mbps) optical SFP transceiver module designed for bidirectional data transmission over single-mode fiber (SMF). It enables cost-effective fiber connectivity by transmitting and receiving data over a single strand of fiber, making it ideal for enterprise and service-provider networks where fiber availability is limited.

This hot-swappable SFP module uses a 1310 nm transmit wavelength and a 1550 nm receive wavelength, allowing it to operate in conjunction with a complementary BX transceiver on the opposite end of the link. Its compact form factor ensures easy installation and high port density in supported Cisco switches and routers.
