SFP transceiver module BlueOptics SFP-GLSD-50A-A-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-GLSD-50A-A-BO is a single-port SFP fiber optic transceiver module designed for single-mode links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 1550 nm. The module has a metal housing, a compact form factor and a weight of approximately 3 g, and is powered from a 3.3 V input supply. It uses an LC duplex optical interface and is intended for reliable long-distance optical connectivity in networking equipment that accepts SFP modules.

Advantages

The transceiver offers compatibility with standard SFP slots and follows MSA-compliant form factors, enabling plug-and-play replacement or upgrade of compatible network ports. Its 1550 nm wavelength and single-mode operation make it suitable for extended reach links. The metal housing provides mechanical protection and thermal stability while the 3.3 V supply and lightweight design simplify integration into switches, routers and other communication devices.

Suitable for

• Single-mode fiber links requiring up to 1250 Mbit/s throughput
• Long-reach optical connections where 1550 nm transmission is required
• Replacement or spare SFP modules in network switches, routers and storage systems

How to use

Install the SFP module into an available SFP slot on compatible networking equipment following the host device manufacturer’s hot‑swap guidelines. Connect single‑mode fiber using an LC duplex patch cable, ensuring correct transmit/receive alignment. Verify link status and required configuration (speed/auto‑negotiation) on the host device. If the host supports digital diagnostics (DDM/DOM), enable or query the diagnostic interface to monitor parameters such as supply voltage, optical power and temperature where supported.

Recommendations

Use single‑mode fiber and LC duplex patch cords matched to the 1550 nm wavelength for optimal reach and performance. Confirm compatibility with the host device firmware for SFP modules and, if remote monitoring is needed, ensure the equipment supports DDM/DOM functionality. Handle the module carefully to avoid contamination of the optical interfaces and follow ESD precautions during installation.
