SFP transceiver modul BlueOptics SFP-GLS-W5320-A-BO 1250 Mbit/s

The BlueOptics SFP-GLS-W5320-A-BO is a single‑mode fiber SFP transceiver module designed for 1000BASE-BX-D applications with a maximum data transfer rate of 1250 Mbit/s. Housed in a metal enclosure and operating at 3.3 V input, this compact silver module weighs approximately 3 g and uses an LC simplex connector to support unidirectional transmit and receive on separate wavelengths (transmit 1310 nm, receive 1550 nm). It complies with MSA SFP form-factor standards and is suitable for integration into network switches, routers and other devices that accept compatible 1000BASE-BX-D SFP modules.

Advantages

The module provides stable gigabit optical transmission with a small form factor and low weight, enabling flexible deployment in dense network environments. Its metal housing supports thermal stability and mechanical protection while the 3.3 V interface ensures compatibility with standard SFP ports. Built to the MSA profile and tested for interoperability, the transceiver supports long-distance single‑mode connectivity and digital diagnostics when the host hardware supports DDM/DOM.

How to use

Before installation, verify that the target switch or router explicitly supports 1000BASE-BX-D SFP modules or compatible third‑party SFPs. Insert the BlueOptics SFP-GLS-W5320-A-BO into an empty SFP port until it clicks into place, then connect an LC simplex single‑mode patch cable with the correct polarity to the transceiver. Configure the host device for the required Ethernet interface and check link status. If the host supports DDM/DOM, monitor supply voltage, laser bias, output power, input power and temperature through the management interface to ensure proper operation.

Recommendations

Use certified single‑mode LC simplex patch cords and, where possible, route fiber through patch panels to maintain optimal signal quality. Confirm DDM/DOM support on your hardware to enable remote diagnostics, and avoid mechanical stress or excessive bending of fiber cables. For long‑term reliability, operate the module within the host’s specified temperature and voltage ranges and follow manufacturer guidelines for hot‑plugging SFP modules.
