Glasvezel-SFP-transceiver BlueOptics 551090-BO 20000 m aluminium

The BlueOptics 551090-BO is a single-mode fiber optic SFP transceiver designed for 1000BASE-BX-U applications and long-distance links up to 20,000 m. Housed in an aluminium casing and weighing just 20 g, this module implements LC Simplex connectivity and supports simultaneous transmit and receive operation over a single fiber by using different wavelengths for transmitter and receiver. The transceiver is built to MSA standards and is suitable for use in switches, routers, storage systems and other network devices that accept standard SFP modules.

Advantages

The module provides long-reach performance for Gigabit Ethernet, Fibre Channel over Ethernet or SDH/SONET applications up to 1.25 Gbit/s while maintaining low weight and a durable aluminium housing. Compliance with MSA specifications ensures interoperability with a wide range of hardware. The design uses proven laser and IC components to provide extended product life and stable optical performance, and the transceiver supports digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host device.

Key specifications

• Transmission standard: 1000BASE-BX-U (1.25 Gbit/s)
• Maximum transfer distance: 20,000 m (single-mode fiber)
• Connector type: LC Simplex
• Optical wavelengths: asymmetric transmit/receive pair for single-fiber operation
• Housing material: aluminium
• Weight: 0.02 kg
• Form factor: SFP (Small Form-factor Pluggable), MSA compliant
• Digital Diagnostics Monitoring (DDM/DOM) supported (if host device supports it)

How to use

Install the SFP module into a compatible SFP slot on your network device following the vendor’s hot‑swap guidelines. Use an appropriate single-mode LC simplex patch cord and ensure correct polarity and fibre routing for single-fibre bidirectional links. Configure the connected devices to the matching transmission protocol and verify link parameters. If digital diagnostics are required, enable and read DDM/DOM values from the host system to monitor voltage, laser current, output/input power and temperature.

Recommendations

For optimal performance, pair the transceiver with single-mode fibre and quality LC connectors, verify that the host device supports 1000BASE-BX-U and DDM if diagnostics are needed, and adhere to manufacturer guidelines for ESD protection and installation. Perform optical loss budget calculations for links approaching the 20 km limit and test with a sample module in your environment before large deployments.
