QSFP-transceivermodule BlueOptics QSFP-40G-LR4-20-PS-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-PS-BO is a QSFP form-factor fiber optic transceiver module designed for 40 Gbit/s links. It supports a maximum data transfer rate of 40000 Mbit/s and is intended for single-mode fiber connections using LC connectors. With a compact QSFP interface and a lightweight 40 g housing, this module is suitable for high-speed data communication in data centers and enterprise network environments where long-reach links are required.

Advantages

This transceiver provides a standardized QSFP interface for easy integration into switches and routers that accept QSFP modules. It supports long-distance transmission up to 20,000 m on single-mode fiber, enabling inter-rack and long-reach uplink connections. The fixed LC connector type ensures compatibility with common duplex single-mode patch cords. The small, lightweight design reduces space and weight in dense optical racks while delivering a stable 40 Gbit/s physical link.

Key specifications

How to use

Install the module into a compatible QSFP port on a switch or router while the host device is powered according to the equipment manufacturer's instructions. Connect duplex single-mode LC patch cords to the module's LC receptacles, observing correct polarity. After physical installation, verify link status and speed on the host device; the module is designed for 40 Gbit/s operation. Follow proper ESD handling procedures when handling the transceiver and keep dust caps on the fiber interfaces until cables are connected.

Recommendations

Use certified single-mode LC patch cords and verify that the host device supports QSFP 40G-LR4 modules. For reliable long-reach performance, ensure fiber path quality and connector cleanliness. Avoid bending the fiber beyond recommended radii and store spare modules with protective dust caps in a dry environment.
