## Summary description

The BlueOptics SFP-BXU35-20KM-SO-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 networking applications.

## Long description

The BlueOptics SFP-BXU35-20KM-SO-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications. It supports a maximum data transfer rate of 1250 Mbit/s, uses an LC simplex connector and transmits and receives on separate wavelengths (transmit 1550 nm / receive 1310 nm) over a single fiber. The module is housed in a durable metal casing, weighs approximately 20 g and is built to meet MSA interoperability standards for use in compatible switches, routers and storage systems.
Advantages
The transceiver offers a compact SFP form factor with broad vendor compatibility and an MTBF of approximately 1,000,000 hours for long-term operation. Its metal housing provides mechanical robustness and electromagnetic shielding. The module supports digital diagnostics (DDM/DOM) for real-time monitoring of parameters such as temperature, supply voltage, laser bias current and optical power, simplifying maintenance and fault analysis.
Suitable for
Point-to-point single-mode fiber links up to 20 km
Gigabit Ethernet (1000BASE-BX-U) connections
Interconnects between switches, routers, storage systems and media converters
Environments requiring remote link monitoring via DDM/DOM
Key specifications
Interface type: SFP (small form-factor pluggable)
Protocol support: 1000BASE-BX-U (Gigabit Ethernet)
Maximum data rate: 1250 Mbit/s
Fiber type: Single-mode fiber (SMF)
Wavelengths: Tx 1550 nm / Rx 1310 nm (BX-U configuration)
Connector: LC simplex
Maximum transmission distance: up to 20 km
Housing: metal
Weight: approx. 0.02 kg
Digital diagnostics: DDM/DOM (MSA SFF-8472 compliant)
How to use
Insert the SFP transceiver into a compatible SFP slot according to the host device documentation until it latches securely. Connect an LC simplex single-mode patch cord between this transceiver and the corresponding remote transceiver, ensuring correct orientation for BX-U (transmit on 1550 nm to the remote receiver at 1310 nm). Verify link status on the host device and, if available, enable or query DDM/DOM telemetry to monitor optical power, temperature and other operating parameters. Always follow electrostatic discharge (ESD) precautions when handling the module and keep protective caps on the optical ports when not in use.
Usage recommendations
Use high-quality single-mode LC patch cords and, where possible, test interoperability with the target hardware. Confirm that the host system supports the BX-U wavelength plan and DDM/DOM if you require diagnostic telemetry. Store and handle the module in a dry, dust-free environment and avoid excessive bending of fiber cabling to maintain optimal optical performance.
