Cisco GLC-FE-100BX-D

The Cisco GLC-FE-100BX-D is a small form-factor pluggable (SFP) transceiver module manufactured by Cisco Systems. It is designed for use in Cisco networking devices and provides a Fast Ethernet (FE) interface. The "100BX" in the model name refers to the transmission speed of 100 Mbps, while the "D" indicates that it is a duplex module. The "FE" signifies that it is compatible with Fast Ethernet networks. The GLC-FE-100BX-D operates using a single strand of single-mode fiber optic cable, allowing for long-distance data transmission. It uses a wavelength of 1310 nm for transmitting data and 1550 nm for receiving data. This SFP module is commonly used in Cisco switches, routers, and other networking equipment to provide connectivity and expand the network's capabilities.
