QSFP112, an advanced iteration of the current QSFP technology, is a new network module and connection system designed to achieve 112Gb/s transmission speed per lane in a four-lane QSFP system, ultimately enabling a QSFP 400G interconnect ecosystem. This innovation offers a significant advantage to users of legacy QSFP systems, allowing them to upgrade their port link bandwidth to 400G with notable benefits.
Optech offers the 400G QSFP112 Transceiver including 400G QSFP112 SR4 and 400G QSFP112 DR4. These can support two interconnect technologies, InfiniBand (IB) and Ethernet (ETH), and are fully compatible with Nvidia devices. Paired with high-speed computing AI devices, they enhance the overall performance of AI networks.
These are used in Nvidia ConnectX-7/OSFP or BlueField-3 adapters connected to twin-port transceivers in dual 400G InfiniBand/Ethernet switches.
