## Summary description

The BlueOptics SFP-BXU35-20KM-QL-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a durable metal housing and has a mean time between failures (MTBF) of 1,000,000 hours. Weighing only 20 g, it is designed for reliable performance in network applications.

## Long description

The BlueOptics SFP-BXU35-20KM-QL-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications. It supports a maximum data transfer rate of 1250 Mbit/s and uses an LC simplex connector with separate transmit and receive wavelengths (transmit 1550 nm, receive 1310 nm) to enable bidirectional transmission over a single fibre. Encased in a durable metal housing, the module weighs approximately 20 g and is intended for long-reach links up to 20 kilometres with support for digital diagnostics (DDM/DOM) when the host hardware provides the interface.
Advantages
The module follows MSA-compliant SFP form-factor standards to ensure mechanical and electrical interoperability with a wide range of network hardware. A metal enclosure provides mechanical robustness and thermal stability while a high MTBF value supports continuous operation in critical network environments. Integrated digital diagnostics monitor parameters such as supply voltage, laser bias current, optical output and input power, and temperature to simplify maintenance and troubleshooting when supported by the system.
Suitable for
Gigabit Ethernet links over single-mode fiber
Long-reach point-to-point connections up to 20 km
Interconnects between switches, routers, and storage systems
Environments that require DDM/DOM monitoring for link diagnostics
Key specifications
Form factor: SFP (MSA compliant)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single-mode
Connector: LC simplex
Wavelengths: TX 1550 nm / RX 1310 nm (1000BASE-BX-U)
Maximum link distance: up to 20 km
Digital diagnostics: DDM/DOM support (requires host support)
Housing: metal
Weight: approx. 0.02 kg
Color: silver
How to use
Insert the SFP transceiver into a compatible SFP slot on the switch, router or storage device until it latches in place, then connect an LC simplex single-mode patch cable to the transceiver. Ensure that the fibre polarity and the device at the other end are configured for 1000BASE-BX-U operation (opposite wavelengths for transmit and receive). Verify that the host device recognizes the module and, if required, enable or check DDM/DOM readings via the management interface to monitor link parameters.
Usage recommendations
Handle the transceiver and fibre connectors carefully to avoid contamination; use dust caps when ports are unused. Confirm compatibility with the host device firmware and enable digital diagnostics only if supported by the hardware. For best performance, use single-mode patch cords and maintain proper fibre management to minimise bend loss and physical stress on the connectors.
