The solution provides a perfect interconnect between QSFP-DD switches and OSFP NICs, solving the problem of adapting between different port packages of the devices.
Cisco Compatible 400G QSFP-DD SR4 PAM4 850nm MTP/MPO-12 OM4 100m Optical Transceiver Module
Cisco compatible QDD-400G-SR4 is a multi-mode 4-channel (SR4) QSFP-DD optical transceiver, designed for 400 Gigabit Ethernet (GbE) links on up to 100m of OM4 multimode fiber. The QDD-400G-SR4 converts 8 input channels of 50Gb/s PAM4 electrical data to 4 channels of 100Gb/s PAM4 optical signals, using a nominal wavelength of 850nm, for 400Gb/s optical transmission. This module reduces the number of fiber channels and can interconnect with 400G SR4 modules on OSFP or QSFP112 adapter cards to meet diverse application scenarios for interconnection between different devices.
