100G QSFP28 LR4 10KM EN network transceiver module BlueOptics

The BlueOptics 100G QSFP28 LR4 10KM EN network transceiver module is a compact fiber optic device designed for 100 Gbit/s data links over single-mode fiber. It uses a QSFP28 electrical interface and LR4 optical specification to support long-distance connections up to 10 kilometers, making it suitable for data center uplinks, aggregation links and carrier networks. The module is lightweight and compact, intended for hot-pluggable installation in compatible QSFP28 ports.

Advantages

This transceiver delivers a high maximum data transfer rate of 100000 Mbit/s while keeping physical size and weight minimal. The LR4 optical design provides consistent performance for single-mode fiber over distances to 10 km, and the QSFP28 interface ensures compatibility with modern 100G switches and network equipment. Its neutral colour and industry-standard form factor allow easy integration into existing racks and systems.

How to use

Install the module into a compatible QSFP28 port on a switch, router or transceiver cage while observing ESD precautions. Ensure the host device supports LR4 optics and 100G operation; after insertion the device and link status can be verified through the host system interface and link LEDs. Terminate single-mode fiber with appropriate LC duplex or MPO/MTP connectors as required by the equipment, and verify link integrity and optical power levels with suitable test equipment.

Recommendations

Use the module with certified single-mode fiber and ensure connectors and patch cords meet LR4 requirements. Maintain a clean fiber environment and follow manufacturer guidelines for optical power budgets and temperature ranges to ensure reliable 100G performance over distances up to 10 km.
