Functional description

The QSFP 100G LR4 is a 4x25G single-mode fiber, hot pluggable optical transceiver, which enables the integration of 4 transmitters, 4 receivers and an optical MUX/ DeMUX into a small form factor package that delivers up to 112 Gbps data link in a compact QSFP28 footprint.

The optical connectivity is based on two Singlemode Fiber (SMF) LC connectors, one for Tx and one for Rx. The Tx and Rx each consist of 4 25GB/s LAN-WDM channels, whose wavelengths are in the 1300nm range. The QSFP28 LR4 transceiver is designed for applications with a reach up to 10km.

Q: What laser brands are used in your optical modules?
A: We use globally trusted brands like Broadcom, Coherent, MACOM, and nLIGHT, ensuring high reliability and scenario-specific performance (e.g., short-reach data centers/long-haul telecom). All products comply with international certifications.
