SLQS-DD-200G-LR4 module is a 200Gb/s transceiver module designed for 10km optical communication applications. The design is compliant to IEEE802.3bs 200GBASE-LR4 standard.

For 200GAUI-8 Electrical interface, the module converts 8 input channels(ch) of 25Gb/s electrical data to 4 channels of LWDM optical signals, and multiplexes them into a single channel for 200Gb/s (PAM4) optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s(PAM4) input into 4 LWDM channels of signals, and converts them to 8 channels output electrical data. For 200GAUI-4 Electrical interface, the module converts 4 input channels(ch) of 50Gb/s electrical data to 4 channels of LWDM optical signals, and multiplexes them into a single channel for 200Gb/s (PAM4) optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 200Gb/s(PAM4) input into 4 LWDM channels of signals, and converts them to 4 channels output electrical data

The central wavelengths of the 4 LWDM channels. It contains a duplex LC connector for the optical interface and a 76-pin connector for the electrical interface. To minimize the optical dispersion in the long-haul system, single-mode fiber (SMF) has to be applied in this module. Host FEC is required to support up to 10km fiber transmission.
