The Huawei 34060917 (OSX040B08) is a high-performance 10G SFP+ BiDi (Bidirectional) optical transceiver designed for long-haul single-fiber transmission. Operating at a bidirectional wavelength pair of 1330nm for transmission and 1270nm for reception, this module enables full-duplex communication over a single strand of single-mode fiber (SMF), effectively doubling fiber utilization and reducing infrastructure costs compared to traditional dual-fiber designs. With a transmission distance of up to 40 kilometers, it is an ideal solution for metropolitan area networks, data center interconnects, and long-haul telecommunications where fiber resources are limited.

• Single‑Fiber Bidirectional Technology: The 34060917 utilizes a BiDi architecture, allowing simultaneous transmission and reception over a single fiber strand. This design effectively doubles the capacity of existing fiber infrastructure while reducing cabling complexity and installation costs.

• 40km Long‑Distance Transmission: With a transmit optical power range of 0 dBm to 5 dBm and a receiver sensitivity of -18 dBm, this module maintains reliable signal integrity over distances up to 40 kilometers on standard single‑mode fiber (G.652), making it ideal for metropolitan area networks and long‑haul connectivity.

• Hot‑Swappable SFP+ Form Factor: The compact SFP+ footprint supports hot-swapping, enabling module replacement or installation without rebooting network equipment, minimizing downtime during maintenance or network upgrades.

• Digital Optical Monitoring (DOM) Support: Integrated DOM provides real‑time access to critical operating parameters including temperature, supply voltage, bias current, transmit optical power, and receive optical power, enabling proactive fault detection and simplified network diagnostics.

• Complementary Pairing Requirement: As a bidirectional module, the 34060917 (1330nm Tx / 1270nm Rx) must be used with a complementary BiDi module at the opposite end of the link – specifically, the Huawei 34060918 (1270nm Tx / 1330nm Rx). Using identical wavelength modules at both ends will cause link failure.

• Full Duplex Communication: The module operates in full‑duplex mode with separate transmit and receive wavelengths, preventing signal interference while allowing simultaneous bidirectional data flow.
