SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-BXU34-40KM-CN-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-CN-BO is a single-mode fiber SFP transceiver module designed for point-to-point 1000BASE-BX-U links. It supports a maximum data rate of 1250 Mbit/s and implements an asymmetric wavelength pair (transmit 1490 nm, receive 1310 nm) over a single strand using an LC simplex connector. Housed in metal and weighing approximately 20 g, the module is built to industry MSA dimensions and provides long-distance optical transmission up to 40 km with integrated digital diagnostics (DDM/DOM) support.

Advantages

The transceiver offers compatibility with a wide range of network equipment that accepts MSA-compliant SFP modules while maintaining stable throughput at 1.25 Gbit/s. Its metal casing and single-mode optical design reduce sensitivity to electromagnetic interference and provide mechanical durability. Integrated digital diagnostics allow remote monitoring of supply voltage, laser bias current, transmit output power, receive input power and temperature. The module’s rated MTBF supports long service life for deployments where continuous availability is important.

How to use

Before installation, confirm that the host device supports MSA-compliant SFP transceivers and that the DDM/DOM function (if required) is supported by the hardware and monitoring software. Insert the module into an empty SFP slot until it latches; connect an LC simplex single-mode patch cable to the transceiver. Ensure correct orientation for the BX-U link: use the designated transmit and receive ends according to network design. After insertion, verify link status and monitor diagnostic parameters via the host interface to confirm optical power and temperature are within expected ranges.

Recommendations

Use high-quality single-mode LC patch cords and, where possible, an appropriate patch panel or mating transceiver to achieve the specified 40 km range. Keep optical connectors clean and capped when not in use to avoid contamination. When deploying in production environments, test interoperability and DDM readings with the target switch or router before large-scale rollout.
