400G QSFP-DD SR4 PAM4 850nm 100m MPO-12/APC MMF Transceiver Module
QSFP-DD 400GBASE-SR4 PAM4 850nm 100m MPO-12/APC MMF Transceiver Module
QSFPDD-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 QSFP-DD 400G SR4 transceiver 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.
