The CT-400G-QDD-FR4 is a hot-pluggable QSFP-DD optical module designed for 400GBASE-FR4 Ethernet applications in data centers and cloud networks. It delivers 400 Gb/s using 8×53. 125 Gb/s PAM4 electrical lanes (400GAUI-8), multiplexed into 4 CWDM optical channels (1271–1331 nm). Each fiber pair link is compliant to 100GBASE-FR1 and thus can support a 400GE to 4x 100GE breakout over 2 km. These signals are then efficiently multiplexed into a single. dule retimed interface (see IEEE 802. 3bs 100GBASE-FR1 specification, with four channels of 100G PAM4 data on parallel single-mode fiber (100G per fiber), with an optical reach of up to 2km. Each optical lane is. On 400G QSFP-DD, PAM4 is enabled by a DSP (digital signal processor) that acts like a gearbox to convert 8 electrical signal channels to 4 optical signal channels. This QSFP-DD transceiver complies with IEEE 802. Always a pleasure working with Christian Quality packaging! Fastest shipments.
