SFP transceiver module BlueOptics ISFP-GIG-BX-D-BO 1250 Mbit/s

The BlueOptics ISFP-GIG-BX-D-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-D links with a maximum data rate of 1250 Mbit/s and an operating range up to 20 km. The module comes in a metal (silver) housing, uses an LC simplex connector and has a compact, lightweight form factor of 20 g. It supports separate transmit and receive wavelengths (1310 nm TX / 1490 nm RX) for single-fiber bidirectional operation and follows MSA-compliant mechanical and optical specifications for broad compatibility with supported networking hardware.

Advantages

The module provides 1.25 Gbit/s optical bandwidth over single-mode fiber with a simplex LC interface, enabling duplex communication on a single fiber. Its metal housing offers mechanical durability while keeping weight low, and the design follows industry MSA standards to ensure interoperability with compatible switches, routers and storage systems. The transceiver supports Digital Diagnostics Monitoring (DDM/DOM) when the host platform exposes that interface, allowing real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature.

How to use

Install the BlueOptics ISFP-GIG-BX-D-BO into an SFP slot of a compatible device according to the device manufacturer's insertion and removal procedures. Connect a single-mode LC patch cable to the module and to the corresponding remote transceiver or patch panel; ensure TX/RX orientation corresponds to the remote end. Verify link status on the host device and, if available, enable or read DDM/DOM parameters from the management interface to monitor optical and electrical parameters. Follow ESD handling guidelines during installation and avoid excessive bending of the fiber to maintain signal quality.

Recommendations

Use high-quality single-mode LC patch cords and, where possible, patch panels to achieve optimal range and signal performance. Confirm that the host hardware firmware or driver supports third-party SFP modules and DDM/DOM access if monitoring is required. For long-term reliability, operate the module within the device temperature range and perform periodic checks of DDM metrics to detect degradation early.
