QSFP+ optical transceivers provide high-bandwidth parallel fiber connectivity for modern data-center switching, routing, and aggregation equipment. These modules use MTP/MPO multimode interfaces to support short-range 40G Ethernet transport over OM3 or OM4 fiber. Their compact QSFP+ form factor reduces port density requirements while enabling scalable high-speed infrastructure designs. These transceivers are commonly deployed in cloud environments, high-performance computing networks, and rack-to-rack optical interconnect applications.
