SFP transceiver module BlueOptics SFP-BXU34-20KM-MA-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-MA-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal casing and weighing approximately 20 g, this compact transceiver supports long-reach links up to 20 km using an LC simplex connector and provides digital diagnostics for real-time monitoring where supported by host hardware.

Advantages

The module follows MSA SFP form-factor standards to ensure interoperability with compatible switches, routers and other networking equipment. It provides separate transmit and receive wavelengths for upstream/downstream operation (transmit ~1490 nm, receive ~1310 nm) and is suitable for deployments requiring stable single-fiber bi-directional links. With an MTBF around 1,000,000 hours and a metal housing, the transceiver is built for continuous operation and reduced maintenance cycles.

How to use

Install the SFP transceiver into an SFP port on compatible networking equipment according to the host vendor’s instructions. Ensure the device firmware or driver supports 1000BASE-BX-U modules and DDM if monitoring is required. Connect an LC simplex single-mode patch cable to the module and to the remote transceiver, taking care to match the transmit and receive ends for bidirectional operation on a single fiber. Verify link status and perform any required configuration on the switch or router to enable the 1.25 Gbit/s interface.

Recommendations

To obtain reliable long-distance performance, use high-quality single-mode fiber and LC simplex patch cords, avoid tight bends in the fiber, and confirm that the host hardware supports DDM to monitor optical parameters such as supply voltage, laser bias current, output power and temperature. Follow ESD handling procedures when installing or removing the module.
