Fiber optic transceiver module BlueOptics GLC-LH-SM-LEG 1250 Mbit/s SFP 1310 nm

The BlueOptics GLC-LH-SM-LEG 1250 Mbit/s SFP 1310 nm is a single-mode fiber optic transceiver module designed for point-to-point and long-reach network links. Operating at 1310 nm with a data rate of 1250 Mbit/s, this SFP form-factor module provides optical connectivity for switches, routers and media converters that accept standard SFP interfaces. It is intended for environments that require single-mode fiber compatibility and reliable optical transmission over extended distances.

Advantages

This transceiver offers a compact SFP form factor that simplifies hot-swapping and modular installation in network equipment. With a fixed 1310 nm wavelength and support for 1250 Mbit/s, it provides predictable performance for standard optical links. The single-mode design reduces signal loss on long-distance connections and helps maintain consistent throughput in point-to-point deployments.

Suitable for

• Long-reach single-mode fiber links between network switches and routers
• Optical uplinks in enterprise and carrier networks
• Integration with media converters and SFP-capable network devices
• Replacement or spare module for SFP slots requiring 1310 nm operation

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Optical wavelength: 1310 nm
• Supported data rate: 1250 Mbit/s
• Fiber type: single-mode fiber (SMF)
• Application: point-to-point and long-reach optical links

How to use

Install the module into an SFP-compatible slot on a switch, router or media converter while the host device is powered according to the equipment manufacturer's guidance for hot-pluggable modules. Connect single-mode fiber patch cords with appropriate connectors to the module's optical port, taking care to observe correct transmit/receive orientation. Verify link status via the host device interface and monitor optical levels and error statistics through the device management tools.

Recommendations

Use matched single-mode fiber and connectors rated for 1310 nm operation and keep connectors clean to minimize signal loss. Confirm compatibility with the host device's SFP support list and consult its documentation for any necessary configuration. For extended-distance links, check optical power budget and, if needed, select appropriate fiber types or amplification to ensure reliable performance.
