SFP transceiver module BlueOptics SFP-GLS-20-A-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-GLS-20-A-BO is a single‑mode fiber SFP transceiver module designed for 1.25 Gbit/s optical links at 1310 nm. Housed in a metal enclosure and powered from a 3.3 V input, this compact module provides reliable point‑to‑point optical connectivity over long distances up to 20 km while weighing approximately 40 g. It uses an SFP form factor and a duplex LC optical interface (compatible with standard single‑mode fibre deployments) for integration into switches, routers and other networking equipment that accept SFP transceivers.

Advantages

The module offers a standardized SFP form factor and metal housing for mechanical stability and thermal conduction. With a maximum data rate of 1250 Mbit/s and a maximum reach of up to 20,000 m on single‑mode fiber, it supports long‑distance Ethernet and related high‑speed optical protocols. Low operating voltage (3.3 V) and compact weight make it suitable for dense installations and hot‑swappable deployment in compatible ports.

How to use

Insert the BlueOptics SFP‑GLS‑20‑A‑BO module into an available SFP slot on compatible network hardware until it clicks into place. Connect a single‑mode LC duplex fiber patch cable to the module’s optical interface, ensuring correct transmit/receive orientation. Power up the host device and verify link status through the device management interface or LEDs. Remove the module by depressing the latch mechanism and pulling it out while the host port is disabled if hot‑swap procedures are required.

Recommendations

For optimum performance, use single‑mode LC duplex patch cords and ensure both ends of the link use transceivers with matching wavelength and specifications. Verify that the host device supports SFP transceivers and, if needed, enable Digital Diagnostics Monitoring (DDM/DOM) in hardware that supports SFF‑8472 to monitor real‑time parameters such as supply voltage, optical power and temperature.
