400G QSFP112 DR4 is designed for use in 400 Gigabit Ethernet links on up to 500m of single mode fiber.

400G QSFP112 DR4 Product Overview

400G QSFP112 DR4 is an optical transceiver module designed for 400G Ethernet data center interconnect in QSFP-DD (Quad Small Form Factor Pluggable-double density ) form factor. On the transmitter end, this DR4 module converts 8 channels of 50Gb/s (PAM4) electrical signal into 4 channels of parallel optical output data, each capable of 100Gb/s data rate for an aggregated bandwidth of 400Gbls. On the receiver side, the optic transceiver converts 4 lanes of parallel optical data of 100Gbp/s each lane for an aggregated of 400Gbp/s to support 8 lanes of 50Gb/s PAM4 electrical output signal.

The 400G QSFP-DD DR4 fiber module achieves the transmission over SMF(single-mode fiber) with an MPO-12 connector. Normally, the 400G transceiver of QSFP-DD DR4 form-factor supports a max transmission distance of 500 meters on 1310nm center wavelength. The product is designed with digital diagnostic functions according to the 400G QSFP-DD Multi-Source Agreement (MSA).
