Colorchip’s 400G QSFP112 VR4 transceiver is designed for use in 400G Ethernet links up to 50m over OM4/OM5 and 30m over OM3 multi-mode fiber. The module converts 4 channels of 100Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s.
On the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 4 channels of 100Gb/s (PAM4) electrical output data.An optical fiber cable with an MTP/MPO-12 connector can be plugged into the QSFP112 VR4 module receptacle. Host FEC is required to support up to OM4/OM5 50m fiber transmission.
