The GLC-FE-100BX-U is a Cisco 100BASE-BX10-U SFP for Fast Ethernet SFP ports. It always links to a 100BASE-BX10-D device, such as the GLC-FE-100BX-D, over a single strand of standard single-mode fiber with an operating transmission range up to 10 km. The two ends must be a matched pair, with a 100BASE-BX10-U module at one end and a 100BASE-BX10-D module at the other.
Two wavelengths share that one strand: the GLC-FE-100BX-U transmits at 1310 nm and receives a 1550-nm signal, and a Wavelength-Division Multiplexing splitter integrated into the SFP separates the two light paths. The connector is a single LC, and the minimum cable distance is 2 meters (6.5 feet).
Cisco specifies transmit power of -14 dBm minimum to -8 dBm maximum and receive power of -28.2 dBm minimum to -3 dBm maximum. The module consumes up to 1 W per port and measures 8.5 x 13.4 x 56.5 mm. Multimode runs at 1300 nm use the GLC-FE-100FX SFP; other Fast Ethernet optics are in Cisco interface cards.
