Cisco QDD-SR4-400G Compatible LINK-PP 400GBASE-SR4 QSFP-DD 8 x 50G PAM4 Transceiver Module (MMF, 850nm, 50m, MTP/MPO-12, DOM)

The Cisco QDD-SR4-400G Compatible LINK-PP module is a four-Channel, Parallel, Pluggable, Fiber-Optic QSFP-DD Module for 400Gigabit Ethernet applications. This product converts 8 channels of 26.5625GBd electrical input data to 4 channels of 53.125GBd parallel optical signals. Reversely, on the receiver side, 4 channels of parallel optical signals of 53.125GBd converts to 8 channels of 26.5625GBd electrical output data. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm, up to 30 meters over OM3 MMF or 500 meters over OM4 MMF.
