## Summary description

The BlueOptics SFP-BXU35-40KM-NG-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, ensuring reliability for network applications.

## Long description

The BlueOptics SFP-BXU35-40KM-NG-BO is a single-mode fiber optic SFP transceiver designed for 1000BASE-BX-U applications. It supports a maximum data transfer rate of 1250 Mbit/s and uses an LC simplex connector to send and receive optical signals on separate wavelengths (transmit 1550 nm / receive 1310 nm). The module features a metal housing, a compact SFP form factor, a weight of 20 g and an MTBF of 1,000,000 hours, providing a reliable option for long-reach links up to 40 km when used with appropriate single-mode fiber.
Advantages
The transceiver is compliant with MSA SFP specifications for plug-and-play interoperability with compatible hardware platforms that support 1000BASE-BX-U modules. Built with a metal enclosure and tested components, it offers long-term availability and stable optical performance for Ethernet and other 1.25 Gbit/s protocols. The module supports Digital Diagnostics Monitoring (DDM/DOM) where the host device allows it, enabling real-time monitoring of optical parameters to simplify maintenance and troubleshooting.
Suitable for
Long-reach single-mode Ethernet connections up to 40 km
Interconnecting switches, routers and storage systems with LC simplex fiber
Networks requiring 1000BASE-BX-U optical links and DDM support
Upgrading or replacing SFP ports in MSA-compliant hardware platforms
Key specifications
Interface type: SFP (small form-factor pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single-mode
Connector: LC simplex
Wavelengths: transmit 1550 nm / receive 1310 nm (BX-U, bi-directional over one fiber pair)
Maximum link distance: up to 40 km (with appropriate fiber and link budget)
Housing: metal
Weight: 0.02 kg
MTBF: 1,000,000 hours
How to use
Install the BlueOptics SFP-BXU35-40KM-NG-BO into an SFP slot of a compatible switch, router or transceiver-capable device while the host is powered according to the device manufacturer's instructions. Connect an appropriate single-mode LC simplex patch cable between the transceiver and the remote transceiver or patch panel. Ensure transmit and receive fibers are correctly routed for BX-U operation (pairing the 1310 nm and 1550 nm directions). Verify link status on the host device and, if available, use the DDM/DOM interface to check supply voltage, laser bias, output/receive power and temperature for diagnostics.
Usage recommendations
Use certified single-mode fiber and quality LC simplex patch cords to achieve the specified 40 km reach. Confirm that the target hardware supports 1000BASE-BX-U and DDM if diagnostics are required. Observe ESD precautions when handling the module and avoid bending or contaminating fiber connectors; clean connectors before mating. For precise link planning, check the optical budget and attenuation of the deployed fiber plant to ensure reliable performance.
