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

The BlueOptics QSFP-40G-LR4-20-RW-BO is a fiber optic QSFP transceiver module designed for 40 Gbit/s Ethernet links. It supports a maximum data transfer rate of 40000 Mbit/s and is intended for long-reach single-mode fiber connections with a maximum transfer distance of up to 20,000 m. The module uses LC fiber connectors and has a compact form factor suitable for QSFP ports on switches, routers and media converters, with a lightweight construction of approximately 40 g.

Advantages

This transceiver provides a QSFP interface for aggregated 40 Gbit/s throughput while maintaining compatibility with standard LC connectors used in long-reach single-mode deployments. Its long maximum transfer distance allows linking equipment across campus or metropolitan networks without intermediate conversion. The compact QSFP form factor frees module slots and supports high-density port configurations, and the low weight helps with secure insertion and handling.

Key specifications

How to use

Install the module into a compatible QSFP slot on a network switch, router or media converter following the host device manufacturer’s instructions. Use single-mode fiber cables terminated with LC connectors to establish the optical link. Ensure proper alignment and secure latching of the module in the port. Verify link status and configuration via the network device management interface; configure interface speeds and protocols according to the network design.

Recommendations

For reliable operation, use single-mode fibers rated for long-reach transmission and maintain clean connector endfaces to avoid signal loss. Confirm optical budget and link attenuation for distances approaching the maximum 20,000 m and adhere to the host device compatibility list for QSFP modules. Handle the transceiver by its housing and use protective caps when not installed.
