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

The BlueOptics QSFP-40G-LR4-20-PT-BO is a QSFP transceiver module engineered for 40 Gbit/s fiber-optic links. It provides long-reach single-mode connectivity over LC interfaces and is intended for use in data centers, core network aggregation and other high-throughput environments. The module is compact and lightweight, supporting transmission distances up to 20,000 m and a maximum data rate of 40,000 Mbit/s while occupying a QSFP form factor compatible with standard QSFP ports.

Advantages

The transceiver delivers high-capacity 40 Gbit/s transmission with LR4 wavelength division multiplexing for extended single-mode reach. Its LC connector interface enables common fiber patching practices and simplifies integration with existing fiber infrastructure. The small, 40 g housing reduces weight and rack-space impact, and the module follows QSFP mechanical and electrical conventions for plug-and-play replacement in compatible network equipment.

Key specifications

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or media converter following vendor instructions for hot-plug handling. Connect LC-terminated single-mode fiber patch cords to the module’s LC ports, ensuring correct polarity and secure connections. After insertion, verify link status and negotiated speed via the host device interface. When removing the module, power down or follow hot-swap guidance from the equipment manufacturer to avoid disrupting traffic.

Recommendations

For reliable long-reach operation use single-mode fiber with appropriate attenuation margins and observe bend-radius limits for patch cords. Confirm compatibility with the host device’s QSFP electrical and firmware requirements before deployment, and monitor link diagnostics where available to detect signal degradation over long distances.
