Quadwire is a family of 4-channel parallel active optical cables that facilitates high-speed data connectivity for storage, networking, and high-performance computing (HPC) applications. It supports up to 4x28Gb/s bi-directional connectivity using parallel multimode fiber (MMF) cables. Based on Finisar’s vertically integrated VCSEL array technology, these cables are compact, lightweight, and low power. Quadwire is ideally suited for data center reaches up to 100 meters for InfiniBand QDR/FDR/EDR, 40/100G Ethernet, SAS, PCIe, and other datacom and HPC applications. Quadwire is available in a point-to-point configuration using QSFP modules on each end, as well as a fanout configuration with a QSFP module on one end and four separate SFP modules at the other ends.
