Cisco ONS-SC-2GE-BX-D 1Gbps 1000BASE‑BX 2‑Channel BiDi SFP (1490 nm TX / 1310 nm RX, 10 km)

The Cisco ONS‑SC‑2GE‑BX‑D is a bidirectional 1000BASE‑BX SFP transceiver designed for the Cisco ONS multiservice transport family. It provides single‑fiber Gigabit Ethernet connectivity using 1490 nm downstream transmit and 1310 nm upstream receive, enabling efficient service delivery in fiber‑constrained metro and access networks.

Engineered for carrier‑grade reliability, this module supports distances up to 10 km over single‑mode fiber and is fully compliant with Cisco’s ONS optical specifications. The BX‑D model is designed to operate as a wavelength pair with the ONS‑SC‑2GE‑BX‑U (upstream) module.
