## Summary description

The BlueOptics SFP-BXU34-40KM-CN-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing, weighs 20 g, and has an MTBF of 1,000,000 hours, making it reliable for long-distance data transmission.

## Long description

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.
Suitable for
Long-distance point-to-point fiber links up to 40 km
1000BASE-BX-U Ethernet connections over single-mode fiber
Interconnection of switches, routers and storage systems with LC simplex ports
Environments requiring DDM/DOM monitoring for remote diagnostics
Key specifications

Fiber type: Single-mode fiber
Wavelengths: TX 1490 nm / RX 1310 nm (BX-U asymmetric operation)
Connector: LC simplex
Maximum link distance: up to 40 km
Housing: metal
Digital diagnostics: DDM/DOM (SFF-8472 compatible)
Colour: silver
Weight: approx. 0.02 kg
MTBF: approx. 1,000,000 hours
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.
Usage 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.
