Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Single-fiber Gigabit Ethernet for metro and access networks — professionally tested and backed by a Lifetime Warranty.
This New Cisco ONS-SC-2GE-BX-D is a 1000BASE-BX BiDi SFP transceiver professionally tested and reset to factory defaults before shipment. Operating at 1490 nm transmit and 1310 nm receive, this downstream (BX-D) module delivers full-duplex Gigabit Ethernet over a single strand of single-mode fiber, eliminating the need for a dedicated fiber pair and making it an ideal fit for fiber-constrained environments. Every unit is sourced, inspected, and certified through WhaleyComm's ISO 9001, R2v3, and e-Stewards certified processes.The ONS-SC-2GE-BX-D is engineered for the Cisco ONS multiservice transport family, supporting distances up to 10 km over single-mode fiber. Designed to pair with the ONS-SC-2GE-BX-U upstream module, it enables efficient bidirectional wavelength multiplexing across a single fiber strand — a proven architecture for metro Ethernet service delivery and ONS 15454-based packet-optical networks. The SFP form factor is hot-swappable and fully compliant with Cisco ONS optical specifications, ensuring seamless integration into existing ONS infrastructure.
Purchasing refurbished from WhaleyComm delivers the same Cisco-grade performance at a fraction of the cost of new, with no compromise on reliability. Trusted by 5,000+ enterprise and carrier customers over 25+ years, WhaleyComm backs every unit with a Lifetime Warranty — because confidence in your hardware should never have an expiration date.

Ideal Use Cases
Metro Ethernet Service Delivery
Provides carrier-grade Gigabit Ethernet transport over single-mode fiber in metro access rings and point-to-point service segments, reducing fiber consumption per service.
Fiber-Constrained Access Networks
BiDi operation over a single fiber strand makes this module well suited for access deployments where available fiber count is limited and installing additional plant is not practical.
Cisco ONS 15454 Gigabit Ethernet Transport
Directly supported on the Cisco ONS 15454 MSTP, M6, M12, SDH, and SONET platforms, enabling native GbE client transport within established SONET and SDH transport frameworks.
Single-Fiber Service Turn-Up
Paired with the ONS-SC-2GE-BX-U module, this transceiver enables bidirectional Gigabit Ethernet service turn-up on a single fiber strand, accelerating provisioning in dense service environments.
Packet-Optical Network Integration
Designed for SONET/SDH and packet-optical environments, the ONS-SC-2GE-BX-D supports mixed-transport architectures where Ethernet and legacy transport services share the same optical infrastructure.

Frequently Asked Questions
Product-specific answers about compatibility, testing, warranty, fulfilment, and purchase confidence.
The BX-D is the downstream module, transmitting at 1490 nm and receiving at 1310 nm. The BX-U is the upstream module with the inverse wavelength pair. Both modules must be used together — one at each end of the single-fiber link — to establish a bidirectional Gigabit Ethernet connection.
The ONS-SC-2GE-BX-D is supported on the Cisco ONS 15454 MSTP, ONS 15454 M6, ONS 15454 M12, ONS 15454 SDH, and ONS 15454 SONET platforms. For compatibility verification specific to your environment, contact our engineering team at +1 214 607-4800 or sales@whaleycomm.com.
No. The ONS-SC-2GE-BX-D is designed exclusively for single-mode fiber and is rated for distances up to 10 km. Using it with multi-mode fiber is not supported and will result in unreliable or failed operation.
Yes. Every WhaleyComm unit ships with a Lifetime Warranty. If it fails under normal operating conditions at any point, we replace it at no cost — no time limits, no questions asked.
Every unit goes through our ISO 9001-certified testing process: full power-on diagnostics, port-by-port functionality testing, firmware verification, factory reset, and final inspection. A Certificate of Testing ships with every unit.
