BlueOptics SFP-1G-BX40-D-BO network transceiver module Fiber optic 1250 Mbit/s

The BlueOptics SFP-1G-BX40-D-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE-BX-D applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a compact metal casing and weighing approximately 3 g, the module operates from a 3.3 V supply and provides LC simplex connectivity for single-fiber bidirectional transmission. It implements a 1310 nm transmitter and a 1490 nm receiver and follows MSA SFP form-factor standards to ensure physical compatibility with a wide range of network devices.

Advantages

The transceiver supports high-speed optical links up to 1.25 Gbit/s over single-mode fiber and is compatible with common networking platforms that accept 1000BASE-BX-D SFP modules. Its metal housing provides durability and thermal stability while the compact SFP form factor keeps space requirements minimal. Built to MSA standards, the module facilitates straightforward installation and replacement in switches, routers and storage systems. Where supported by the host hardware, Digital Diagnostics Monitoring (DDM/DOM) provides real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature.

Suitable for

• Point-to-point single-mode fiber links up to 40 km
• Gigabit Ethernet connections (1000BASE-BX-D)
• Interconnects between switches, routers and storage systems
• Environments requiring compact, hot‑pluggable SFP modules

• Digital Diagnostics Monitoring (DDM/DOM): supported when host hardware allows

How to use

Install the BlueOptics SFP-1G-BX40-D-BO by inserting the module into an available SFP port on a compatible switch, router or media converter while the device is powered down or hot-plugging if the host supports it. Connect an LC simplex single-mode fiber patch cord with correct polarity to establish the bidirectional link—one fiber carries transmit and receive signals on different wavelengths. Configure the host interface for 1000BASE-BX-D or the appropriate Gigabit Ethernet mode if necessary, and verify link status via the host device management interface. If DDM/DOM is required, confirm the host platform exposes diagnostic registers to read real-time parameters.

Recommendations

Use high-quality single-mode LC patch cords and, where applicable, patch panels to achieve optimal range and signal quality. Ensure the host device firmware supports third-party SFP modules and DDM/DOM if remote diagnostics are needed. Avoid exposing the module to excessive mechanical stress or contamination of the optical connector; keep dust caps on when not in use and follow standard fiber‑handling procedures.
