SFP Transceiver Module BlueOptics SFP-BXU35-20KM-MR-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-MR-BO is a single-mode fiber optic SFP transceiver module designed for point-to-point optical links up to 20 km. It supports a maximum data rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex interface following MSA form-factor specifications. The module has a metal housing, a compact SFP footprint, and a stated mean time between failures (MTBF) of 1,000,000 hours, providing a reliable compact solution for network devices that accept standard SFP transceivers.

Advantages

The module implements a 1000BASE-BX-U transmit/receive scheme with a 1550 nm transmitter and a 1310 nm receiver optimized for single-mode fiber, allowing bidirectional communication over a single fiber. Compliance with MSA mechanical and electrical standards ensures interoperability with a wide range of switches, routers and optical equipment that support SFP optics. The metal housing and small form factor contribute to mechanical durability and efficient port density. Integrated digital diagnostics (DDM/DOM) support enables real-time monitoring of supply voltage, laser bias current, optical output power, received power and temperature when supported by the host device.

How to use

Install the SFP transceiver into a compatible SFP slot on the network device until it latches, following the device manufacturer’s guidelines for hot-pluggable optics. Connect an LC simplex single-mode patch cable between this transceiver and the remote transceiver, ensuring correct polarity for bidirectional single-fiber operation (transmit to receive). Verify link status and, if available, read DDM/DOM parameters through the host device to confirm optical levels and module health. Follow electrostatic discharge (ESD) precautions when handling the module and protect unused ports with dust caps.

Recommendations

Confirm host compatibility with 1000BASE-BX-U (bi-directional single-fiber) optics and ensure the network device supports DDM if diagnostics are needed. Use quality single-mode fiber and LC simplex patch cords matched to the module’s wavelengths, and keep transceiver firmware and device drivers up to date for reliable operation.
