SFP Transceiver Module BlueOptics SFP-GLSD-30A-A-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-GLSD-30A-A-BO is an SFP fiber-optic transceiver module designed for 1000BASE-LH single-mode links. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 1310 nm. Housed in a metal enclosure and powered by a standard 3.3 V supply, the module is compact and lightweight (approx. 3 g) for straightforward installation in SFP-capable switches, routers and network devices that accept MSA-compliant SFP modules.

Advantages

The transceiver provides a stable 1.25 Gbit/s optical interface using LC duplex connections appropriate for long-reach single-mode fiber links. Its metal housing offers mechanical robustness and thermal conduction while the low weight and SFP form factor enable easy hot-plug replacement. The module conforms to common MSA SFP physical and optical standards and is intended for direct compatibility with devices that support the original 1000BASE-LH SFP form factor.

Suitable for

• Single-mode fiber backbone links up to long-reach distances (1000BASE-LH applications)
• Media conversion and uplink connections between switches and routers
• Enterprise and service provider network equipment supporting SFP modules
• Storage and data centre interconnects requiring 1.25 Gbit/s optical ports

Key specifications

• Interface type: SFP (small form-factor pluggable)
• Nominal data rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 1310 nm
• Connector type: LC duplex optical connector
• Power supply: 3.3 V input
• Housing material: metal enclosure
• Weight: approx. 0.003 kg
• Colour: silver

How to use

Install the module into an SFP port on compatible network equipment while the host device is powered on or off according to the device manual; the SFP form factor supports hot-pluggability in most systems. Connect an LC duplex single-mode fiber patch cable with correct polarity between transceivers at both ends of the link. Verify that the host device recognizes the module and that link LEDs indicate a successful optical connection. Ensure the host device is configured for the intended network protocol and data rate.

Recommendations

Use single-mode fiber rated for long-reach (1000BASE-LH) applications and LC duplex patch cords to achieve optimal link distance and signal quality. Confirm that the network equipment firmware supports third-party SFP modules and, if available, enable digital diagnostics (DDM/DOM) in the host to monitor supply voltage, laser bias current, output power, received power and temperature for proactive maintenance.
