SFP transceiver module BlueOptics SFPGLX20B13D-BO 1250 Mbit/s

The BlueOptics SFPGLX20B13D-BO is an SFP fiber-optic transceiver module designed for single-mode applications with a maximum data transfer rate of 1250 Mbit/s. The module has an SFP interface and an LC simplex connector, is finished in silver and weighs approximately 20 g. It supports 1000BASE-BX-U style single-fiber operation with distinct transmit and receive wavelengths suitable for point-to-point links over long distances.

Advantages

The module follows MSA SFP form-factor standards for electrical, mechanical and functional interoperability with compatible networking hardware. It supports simultaneous transmit and receive over a single fiber using different wavelengths and is compatible with devices that accept equivalent 1000BASE-BX-U SFP transceivers. The transceiver is suitable for Ethernet and related high-speed optical protocols up to 1.25 Gbit/s and is intended for use where EMI immunity and long-distance optical links are required.

Suitable for

• Point-to-point single-mode fiber links
• Switches, routers and storage systems that accept SFP modules
• Ethernet and Fibre Channel over Ethernet up to 1.25 Gbit/s
• Environments requiring EMI-immune optical connections

Key specifications

• Interface type: SFP (MSA-compliant form factor)
• Maximum data transfer rate: 1250 Mbit/s
• Connector: LC simplex
• Fiber type: Single-mode fiber
• Operating wavelengths: separate transmit and receive wavelengths for BX operation (single-fiber)
• Typical operating range: links designed for long-distance single-mode transmission (up to tens of kilometres depending on link budget)
• Product colour: Silver
• Weight: approx. 0.02 kg

How to use

Install the BlueOptics SFPGLX20B13D-BO into an SFP slot of a compatible switch, router or storage device while the host is powered down or following the vendor’s hot‑swap procedure. Connect an LC simplex single-mode patch cable between this transceiver and the remote BX transceiver, observing correct polarity and the required pairing of transmit/receive wavelengths. Configure the host device for the desired interface speed and protocol; many devices auto-negotiate 1.25 Gbit/s operation. If supported by the host, enable and monitor the Digital Diagnostics Monitoring (DDM/DOM) functions for real‑time status of supply voltage, temperature, transmit and receive power levels.

Recommendations

Use high-quality single-mode LC simplex patch cords and ensure link budget and wavelength pairing are appropriate for 1000BASE-BX-U operation. Verify that the host hardware supports third‑party or equivalent SFP modules and, if available, enable DDM/DOM monitoring for proactive maintenance. Follow ESD handling precautions when installing or removing the module.
