QSFP transceiver module BlueOptics QSFP-40G-LR4-20-SP-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-SP-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s links. Designed for use in high-speed networks, this module supports long-reach optical transmission and fits QSFP ports in switches, routers and media converters. Weighing 40 g and fitted with LC connectors, it provides a compact interface for reliable 40 Gb/s connectivity over single-mode fiber.

Advantages

This transceiver offers 40 Gbit/s line rate performance with LR4 long-reach capability, enabling optical links up to 20,000 m over appropriate single-mode fiber. The QSFP form factor provides high port density while LC duplex connectivity ensures broad compatibility with existing fiber infrastructure. The module’s lightweight construction and standardized QSFP interface simplify installation and replacement in active network equipment.

How to use

Install the QSFP transceiver into an available QSFP socket on compatible network equipment until it latches. Connect LC-terminated single-mode fiber cables to the module’s LC ports, observing correct transmit/receive orientation. Ensure the connected switch, router or media converter port is configured for 40 Gb/s operation and that link settings (speed, duplex, auto-negotiation) are compatible. Monitor link indicators and management interfaces for status and diagnostics after installation.

Recommendations

Use single-mode fiber rated for LR4 distances and maintain proper fiber cleanliness when connecting LC connectors. Verify compatibility with the host device’s QSFP specifications and firmware. For long-span links, plan for optical budget margins and consider using external amplification or dispersion management only if supported by system design.
