## Summary description

The BlueOptics SFP-BXU35-40KM-SS-BO is a fiber optic network 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, ensuring reliability and durability for network applications.

## Long description

The BlueOptics SFP-BXU35-40KM-SS-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U applications with a maximum data rate of 1250 Mbit/s. The module has a metal housing, LC simplex interface and a compact SFP form factor. It supports long‑distance links up to 40 km over single‑mode fiber and includes Digital Diagnostic Monitoring (DDM) capabilities where supported by the host device.
Advantages
The transceiver offers an industry‑standard SFP interface for easy hot‑plug installation and interoperability with MSA‑compliant equipment. Its metal housing and a rated MTBF of 1,000,000 hours provide mechanical robustness and long operational life. With support for 1000BASE‑BX‑U signalling and LC simplex connectors, the module enables simultaneous transmit and receive on separate wavelengths optimized for long‑reach single‑mode transmission.
Suitable for
 Fiber backbone connections between buildings or sites up to 40 km
 Gigabit Ethernet links in switches, routers and media converters
 Long‑reach fiber uplinks in data centers and campus networks
 Environments requiring DDM/DOM monitoring for link diagnostics
Key specifications
 Form factor: SFP (Small Form‑Factor Pluggable)
 Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
 Optical mode: Single‑mode fiber
 Connector type: LC simplex
 Wavelength: Bi‑directional (separate TX/RX wavelengths: 1550 nm / 1310 nm)
 Maximum reach: up to 40 km
 Housing material: metal (silver colour)
 Weight: 0.02 kg
 Digital Diagnostics: DDM/DOM support (if supported by host hardware)
How to use
Insert the BlueOptics SFP‑BXU35‑40KM‑SS‑BO into an empty SFP cage on a compatible switch, router or media converter while the host device is powered according to the vendor’s instructions. Use an appropriate single‑mode LC patch cable to connect to the remote transceiver, ensuring correct orientation for LC simplex connections and matching the required bi‑directional wavelengths on each end. Verify link status through the host device interface and enable DDM/DOM monitoring if the platform supports it.
Usage recommendations
Confirm host compatibility with 1000BASE‑BX‑U SFP modules and ensure fiber patch cords and splices meet single‑mode specifications. For reliable long‑reach performance, use low‑loss connectors and maintain proper cleaning procedures for fiber endfaces. If link diagnostics are required, enable DDM/DOM in the host and monitor real‑time parameters such as optical power and temperature.
