QSFP Transceiver-module BlueOptics QSFP-40G-LR4-20-MA-BO 40000 Mbit/s

The BlueOptics QSFP-40G-LR4-20-MA-BO is a QSFP form-factor fiber optic transceiver module designed for 40 Gbit/s Ethernet links. It supports a maximum data transfer rate of 40000 Mbit/s and is intended for single-mode fiber applications with LC connectors. The module is compact and lightweight (approximately 40 g), providing a long reach of up to 20,000 m for backbone and inter-data center connections where QSFP interfaces are required.

Advantages

This QSFP transceiver combines high throughput and long-distance capability in a small, standardized QSFP package. The LC fiber optic connector ensures compatibility with common single-mode cabling, while the 40 Gbit/s capacity supports aggregation and high-bandwidth links. Its lightweight construction simplifies installation and reduces strain on equipment cages that accept QSFP modules.

Key specifications

How to use

Handle the module by its edges and insert it into a compatible QSFP port on a switch, router or media converter chassis following the host equipment manufacturer’s hot-plug instructions. Connect the LC-terminated single-mode fiber patch cords to the module’s LC receptacles, taking care to match transmit and receive fibers. Verify link status and transceiver diagnostics via the host device management interface to confirm proper operation.

Recommendations

Use appropriate ESD precautions when handling the transceiver, keep the optical ports capped when not in use to prevent contamination, and ensure fiber connectors are clean before mating. Select single-mode fiber cabling rated for long-reach transmission and check device compatibility lists if required by the network equipment vendor.
