## Summary description

The BlueOptics SFP-BXU35-40KM-MA-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 a reliable choice for network applications.

## Long description

The BlueOptics SFP-BXU35-40KM-MA-BO is a single-mode fiber optic SFP transceiver designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal case and weighing approximately 20 g, this module supports long-distance optical links up to 40 km using LC simplex connectors and separate transmit/receive wavelengths (transmit 1550 nm / receive 1310 nm). It follows MSA SFP form-factor standards and includes Digital Diagnostics Monitoring (DDM/DOM) capability when supported by host hardware.
Advantages
The module provides stable 1.25 Gbit/s data transmission over single-mode fiber with a compact SFP form factor and metal housing for mechanical robustness and EMI protection. With an MTBF around 1,000,000 hours and compliance with industry standards, it delivers predictable long-term availability for network links. The LC simplex interface and support for 40 km reach make it suitable for access and metro connections where single-fiber bidirectional operation (BX-U) is required.
Suitable for
 Gigabit Ethernet links over single-mode fiber using 1000BASE-BX-U
 Long-distance point-to-point connections up to 40 km
 Integration into switches, routers, and storage systems with SFP ports
 Networks requiring DDM/DOM monitoring for link diagnostics (if supported by host)
Key specifications
 Form factor: SFP (Small Form-factor Pluggable)
 Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
 Fiber type: single-mode fiber
 Connector: LC simplex
 Wavelengths: TX 1550 nm / RX 1310 nm (BX-U single-fiber bidirectional)
 Maximum link length: up to 40 km (typical, depends on fiber and loss budget)
 Housing: metal
 Color: silver
 Weight: approx. 0.02 kg
 Digital diagnostics: DDM/DOM supported (requires host support)
How to use
Insert the SFP transceiver into a compatible SFP slot on the switch, router or other network device while the device is powered according to the vendor's hot-plug guidelines. Connect an LC simplex single-mode patch cable between this transceiver and the corresponding remote SFP transceiver; ensure the remote side uses the complementary BX direction (one side TX 1550/RX 1310 and the other side TX 1310/RX 1550). Verify link status via the host device interface and, if available, read DDM/DOM parameters for optical power, temperature and supply voltage to confirm proper operation.
Usage recommendations
Use high-quality single-mode fiber and LC simplex patch cords to achieve the specified 40 km reach. Confirm that the host hardware supports 1000BASE-BX-U and DDM/DOM if remote diagnostics are needed. Follow ESD precautions during insertion or removal and avoid bending the fiber beyond recommended radii to maintain link performance.
