Glasvezel transceiver module BlueOptics GSLC30-LXH-BO 40000 m

The BlueOptics GSLC30-LXH-BO is an SFP fiber optic transceiver module designed for single-mode optical links up to 40,000 m. Housed in an aluminium casing and weighing approximately 20 g, the module implements 1000BASE-LH signalling with LC duplex connectivity and 1310 nm transmit and receive wavelengths. It supports standard MSA form-factor compatibility for straightforward integration into switches, routers, storage systems and other network devices that accept SFP modules.

Advantages

This SFP module provides long-reach optical transmission with immunity to electromagnetic interference and low latency characteristics common to fiber links. Manufactured to MSA standards and populated with high-quality optical and electronic components, it offers reliable operation and extended service life. The module supports Digital Diagnostics Monitoring (DDM/DOM) where host devices provide that support, enabling real-time reporting of operational parameters.

Suitable for

• Long-distance Ethernet connections (up to 40 km) over single-mode fiber
• Inter-switch and switch-to-router uplinks in campus and metropolitan networks
• Storage network links and SAN interconnects supporting 1.25 Gbit/s
• Industrial or EMI-sensitive environments requiring fiber connections

Key specifications

• Form factor: SFP (MSA compliant)
• Data rate: up to 1.25 Gbit/s (1000BASE-LH)
• Wavelength: 1310 nm (Tx and Rx)
• Fiber type: single-mode fiber
• Maximum reach: up to 40,000 m (40 km)
• Connector: LC duplex
• Housing material and colour: aluminium
• Weight: approx. 0.02 kg
• Digital diagnostics: DDM/DOM support (requires host support)

How to use

Install the BlueOptics GSLC30-LXH-BO by inserting it into an SFP slot on a compatible network device until it latches. Connect LC duplex single-mode fiber patch cords to the module’s LC ports, observing correct Tx↔Rx polarity. Ensure the host device supports the intended protocol (1000BASE-LH) and, if needed, enable or verify DDM/DOM monitoring in the host management interface. Verify link status and perform any required configuration on the connected network equipment.

Recommendations

To achieve optimal performance, use single-mode fiber and high-quality LC duplex patch cords, keep connector endfaces clean, and verify polarity and link parameters during installation. Confirm that the target device supports SFP 1000BASE-LH modules and DDM if diagnostics are required. Store and handle the module in accordance with standard ESD precautions to protect internal components.
