GIGALIGHT 40G QSFP+ SR BiDi optical transceiver is designed for short-distance interconnection between devices within data centers. It complies with the 40G Ethernet transmission protocol. When upgrading the network architecture from 10G to 40G, it can directly utilize the existing LC duplex cabling infrastructure without the need for additional MPO cabling. This product converts XLPPI 4x10G signals into two 20G signals and achieves 40G total bandwidth transmission over two single-fiber bidirectional channels. Each channel uses a different operating wavelength (850nm or 900nm), and the maximum transmission distance is up to 100m (OM3 MMF) or 150m (OM4 MMF).
