SFP transceiver modul BlueOptics SFP-BXU34-40KM-BC-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-BC-BO is a single-mode SFP transceiver module designed for long-distance optical links with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, the module follows MSA mechanical form-factor and is intended for use in network platforms that accept SFP modules. It supports point-to-point single-fiber operation using LC simplex connections and is rated for high availability with a mean time between failures (MTBF) of 1,000,000 hours.

Advantages

The module combines a compact SFP form factor with a metal housing for mechanical durability and thermal stability. With a 1250 Mbit/s line rate and support for single-mode fiber over long distances, it provides a standardized optical interface for switches, routers and other SFP-capable equipment. The verified MTBF indicates suitability for installations requiring long continuous operation. Its light weight and standardized connector type simplify installation and replacement in existing fiber infrastructures.

How to use

Install the SFP transceiver into an available SFP slot on a compatible switch, router or storage device while the device is powered down or following the equipment manufacturer's hot‑swap guidance. Connect a single-mode LC simplex patch cable between transceivers or to a patch panel to complete the optical link. Ensure the host device recognizes the module and, if required, enable or verify digital diagnostics (DDM/DOM) in the host management interface. Observe standard electrostatic discharge (ESD) precautions and keep dust caps in place on unused ports.

Recommendations

Use quality single-mode LC simplex fiber patch cords and ensure both ends of a single-fiber BX link use compatible transmit/receive wavelengths. Verify that the host hardware supports 1000BASE-BX-U optics and DDM/DOM if you require real-time diagnostics. For best results, follow the equipment vendor's compatibility list and perform a link test after installation.
