FAQ
The 40G QSFP+ IR4 PSM4 Optical Transceiver is a long-reach parallel single-mode fiber solution designed for high-performance data center and telecom interconnects. Operating in the 1310nm wavelength band, it uses a 4-channel PSM4 architecture over a 12-fiber MPO interface to deliver stable 40Gbps transmission over distances up to 10 km.
Built for QSFP+ MSA compliance, this module enables high-density, low-latency communication in modern leaf-spine architectures and backbone networks. The hot-pluggable QSFP+ form factor simplifies deployment, while the MPO interface ensures efficient parallel optical connectivity across multiple lanes.
