SFP transceiver modul BlueOptics SFP-BXU35-40KM-AR-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-AR-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U Ethernet links with a maximum data rate of 1250 Mbit/s. The module uses an LC simplex connector and implements separate transmitter and receiver wavelengths (transmit 1550 nm / receive 1310 nm) to enable bidirectional transmission over a single fiber. Housed in a metal casing and weighing approximately 20 g, the module provides mechanical durability and compact compatibility with SFP ports that follow MSA specifications.

Advantages

This BlueOptics SFP transceiver offers a standardized SFP interface for broad interoperability with switches, routers and storage systems that accept MSA-compliant modules. Its single-mode design and 40 km reach make it suitable for long-distance links while maintaining a 1.25 Gbit/s nominal data rate. The metal housing improves durability and thermal characteristics, and the module includes digital diagnostics monitoring (DDM/DOM) capability for real-time monitoring of optical parameters when supported by the host device.

Key specifications

How to use

Insert the SFP transceiver into an empty SFP port of an MSA-compatible network device until it clicks into place, taking care to align the module and follow the host vendor's insertion procedure. Connect an LC simplex single-mode patch cable between the module and the remote transceiver, ensuring the correct orientation for bi-directional wavelengths (TX to RX). Verify that the host device recognizes the module and, if available, enable or check digital diagnostics monitoring to view optical parameters such as temperature, supply voltage and optical power.

Recommendations

Install the module in equipment that officially supports MSA-compliant SFPs and verify compatibility with the host vendor. Use single-mode LC simplex patch cables rated for the intended distance and keep fiber connectors clean to maintain signal quality. If DDM/DOM functionality is required for monitoring, confirm that the receiving hardware exposes these diagnostics. Avoid mechanical stress and extreme temperatures to preserve expected MTBF and operational stability.
