GLC-BX80-D-I

The GLC-BX80-D-I from Cisco is the downstream counterpart (D = Downstream) of the GLC-BX80-U-I: a ruggedised BiDi 1 Gbps SFP transceiver over single-mode fibre, capable of reaching 80 km on a single strand. It operates in tandem with the upstream module to establish an 80 km full-duplex BiDi link, saving one fibre strand compared to a traditional duplex solution. Industrial temperature: -40 to +85 °C, LC UPC connector, single-strand cable.

The typical use case for the GLC-BX80-D-I is connecting remote sites in rural or peri-urban areas where fibre cable density is low and every available strand is valuable. Telecom operators, ISPs and local authorities deploying FTTx or long-distance backhaul networks favour this BiDi solution. Genuine Cisco hardware, manufacturer warranty.
