SFP transceiver modul BlueOptics SFP-GLX-LCI-40E-BO 1250 Mbit/s 1310 nm

The BlueOptics SFP-GLX-LCI-40E-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data rate of 1250 Mbit/s and an operating wavelength of 1310 nm. Housed in a metal casing and powered by a 3.3 V supply, the module uses an LC duplex connector and weighs approximately 3 g. It follows MSA-compatible form factors and is suitable for insertion into SFP ports on switches, routers and other networking equipment that support 1000BASE-LH style optics.

Advantages

The module provides Gigabit-class optical transmission over single-mode fiber with simultaneous transmit and receive channels via LC duplex interface. Metal housing offers mechanical stability and heat dissipation, while the small SFP form factor enables flexible deployment in chassis and compact devices. Compliance with MSA dimensions and common optical specifications ensures interoperability with a wide range of network hardware. Low weight and standard 3.3 V operation simplify installation and integration.

Suitable for

• Single-mode fiber links up to multimode-equivalent distances for 1000BASE-LH applications
• Switch-to-switch and switch-to-router Gigabit uplinks
• Storage and server connectivity in data center or campus networks
• Replacement or spare SFP modules in MSA-compliant equipment

Key specifications

• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Optical wavelength: 1310 nm (TX and RX)
• Connector: LC duplex
• Fiber type: single-mode fiber
• Housing material: metal
• Operational voltage: 3.3 V
• Weight: approx. 3 g

How to use

Insert the BlueOptics SFP-GLX-LCI-40E-BO into a compatible SFP slot on your network device while the device is powered on or according to the host manufacturer’s hot-swap guidance. Connect LC duplex single-mode patch cords to the module’s LC receptacle, ensuring correct TX/RX orientation. Verify link/activity LEDs on the host device and check interface parameters in the device management interface. If the host supports digital diagnostics (DDM/DOM), enable or query the diagnostic registers to monitor real-time parameters such as supply voltage, laser bias, optical output/input power and temperature.

Recommendations

Use single-mode LC duplex patch cords and ensure fiber connectors and ports are clean before insertion to maintain signal quality. Confirm that the host device supports 1000BASE-LH optics and, if remote monitoring is required, that DDM/DOM is supported by both module and host. For long-term reliability, avoid excessive mechanical stress on the transceiver and follow ESD handling precautions during installation and removal.
