Cisco GLC-BX-20U 1.25G BIDI SFP 1310nm 1550nm 20km SMF Simplex LC Transceiver

Description Of Fiber Optic Transceiver

The modern network widely chooses optical fiber for long-distance connection. However, the limited fiber resources and high infrastructure investment restrict the network development of some undeveloped regions.  To save fiber resources, many operators favor the application of bidirectional optical transceivers which only use single-core rather than dual-core fiber for optical transmission. The BIDI transceivers can cut half of the new fiber investment and offer double bandwidth with the existing fiber resources. The BIDI transceivers serve as the cost reduce solution against the traditional duplex transceivers for Metro, Long haul network configuration.

TBD-1.25G-20A/20B is a bidirectional Hot-pluggable SFP Form optical transceiver. TBD-1.25G-20A/20B features the BIDI wavelength of 1310nm and 1550nm to offer the max transmission of 20km via G.652 Singlemode Fiber. TBD-1.25G-20A/B features a Simplex LC connector and is fully compliant with BIDI SFP MSA. TBD-1.25G-20A/B can guarantee compatible with Cisco Catalyst and Nexus switches and Routers to replace Cisco GLC-BX-20U GLC-BX-20D for 1000BASE-LX/LH application.
