BlueOptics SFP-1000BASE-BX20-D1550LC-BO network transceiver module Fiber optic SFP interface LC connector

The BlueOptics SFP-1000BASE-BX20-D1550LC-BO is a fiber optic network transceiver module for SFP interfaces with an LC simplex connector. Constructed in aluminium and weighing approximately 20 g, this module implements a bidirectional single‑mode link with separate transmit and receive wavelengths (TX 1310 nm / RX 1550 nm) suitable for 1.25 Gbps optical Ethernet and compatible high‑speed applications over distances up to 20 km when used with appropriate single‑mode fiber.

Advantages

This SFP module follows MSA form‑factor standards for broad compatibility with SFP ports and is designed for reliable single‑mode fiber links. Its compact aluminium housing offers mechanical durability and thermal stability while keeping weight low. The module supports common use cases such as Ethernet and Fibre Channel over Ethernet up to 1.25 Gbps and can provide digital diagnostic monitoring (DDM/DOM) when the host equipment supports that feature. Designed and tested for interoperability, it is suitable as a replacement or spare module in networks that require optical links with LC connectorization.

Key specifications

How to use

Insert the SFP module into a compatible SFP slot according to the host device instructions until it latches. Connect a single‑mode LC patch cable between this module and the remote transceiver or patch panel; ensure correct alignment for simplex LC connections and observe fiber polarity for bidirectional BX links. Verify link status and speed in the host device management interface. If available, enable DDM/DOM in the host to monitor diagnostic parameters such as supply voltage, laser bias, output and receive power, and temperature.

Recommendations

Use single‑mode fiber and LC simplex patch cords rated for the intended distance. Ensure the host device supports 1000BASE‑BX D operation and DDM/DOM if remote diagnostics are required. Handle the transceiver with antistatic precautions and keep dust caps on unused ports to protect optical surfaces.
