SFP transceiver modul BlueOptics SFP-BXD43-20KM-LS-BO 1250 Mbit/s

The BlueOptics SFP-BXD43-20KM-LS-BO is a single-mode fiber optic SFP transceiver module designed for 1250 Mbit/s data transmission over distances up to 20,000 m. Housed in a metal casing and finished in silver, the module uses an LC simplex connector and weighs approximately 0.02 kg. It implements the 1000BASE-BX-D signaling scheme with separate transmit and receive wavelengths suitable for point-to-point links in telecom and enterprise networks.

Advantages

The transceiver provides stable single-mode optical links with a compact metal form factor that supports hot-plug installation into compatible SFP ports. Its LC connector and standardized MSA-compatible design ensure interoperability with a wide range of switches, routers and media converters that accept 1000BASE-BX-D SFP modules. The module’s lightweight metal housing contributes to mechanical durability while maintaining thermal stability for continuous operation.

How to use

Insert the BlueOptics SFP-BXD43-20KM-LS-BO into an empty SFP slot of a compatible network device while the device is powered on or off according to the device manual; the module supports hot-plugging in compliant hardware. Connect a single-mode LC patch cable to the LC simplex port and route the fiber to the remote transceiver or patch panel. Configure the host device for the appropriate 1.25 Gbps optical interface and verify link status through the switch or router management interface. If your network equipment supports digital diagnostics (DDM/DOM), enable and monitor parameters such as optical power and temperature where available.

Recommendations

Use single-mode LC patch cords and follow standard fiber handling practices: avoid sharp bends, keep connectors clean using appropriate cleaning tools, and secure fibers to prevent strain. Confirm compatibility with the host device and, if required, enable DDM/DOM support in the equipment to monitor operational parameters. For reliable long-distance performance, use appropriately certified single-mode fiber and maintain connector cleanliness.
