The 400G QSFP-DD ER4-Lite incorporates EML TOSA and APD ROSA with LWDM grid Mux and De-Mux technology. A DSP gearbox is used to convert 8 channels of 25GBaud PAM4 signals into 4 channels of 50GBaud PAM4 signals. An 8-channel re-timer is integrated in the DSP. The electrical interface is compliant with IEEE 802.3bs and QSFP-DD MSA in the transmitting and receiving directions, and the optical interface is compliant to IEEE 802.3bs with duplex LC connector.
"Our QSFP-DD ER4-Lite optics is designed to support 400G bandwidth over 30~40km transmission distance in a single duplex fiber. It offers the highest faceplate density in QSFP-DD form factor with a low power consumption of 10W or less. This module is an ideal solution to address the ultra-high bandwidth need for connecting data center clusters in a campus or metro environment. An OSFP version of ER4-Lite will also be available upon request," said Osa Mok, Chief Marketing Officer of InnoLight Technology.
