GIGALIGHT Launches a Series of 400G Long-Reach 8-lane Transceivers to Provide Metro Telecom and DCI within 40km a Definite Solution

Shenzhen, China, Nov 23, 2022 – As an 8-lane optics advocate, GIGALIGHT launches a series of new products to boost its market application. The company believes that this family of products will inject long-term reliability into metro telecom transport network and metro DCI network with its high performance and low latency.
From 200G to 800G, GIGALIGHT insisted on taking a different approach, focusing on the development of 8-lane optics architecture based on 25G NRZ, 50G PAM4 and 100G PAM4, and formed a rich product line.
The newly launched 400G long-reach 8-lane optical transceivers adopt the optoelectronic integrated design based on 50G PAM4 DSP to ensure excellent signal integrity and performance. These modules support both 400G Ethernet and OTN, suitable for data center and telecommunications networks.
400G xR8 Transceivers Reach Transmitter Receiver OMA RXsen (@ 2.4E-4 Pre-FEC 26.5625GBd) Maximum Power Consumption
400G QSFP-DD LR8 10km LAN-WDM EML DEMUX + PIN -7.1dBm 12.5W
400G QSFP-DD XLR8 20km LAN-WDM EML DEMUX + PIN -9.1dBm 12.5W
400G QSFP-DD ER8 40km LAN-WDM EML DEMUX + APD -16.1dBm 15.4W
In addition, GIGALIGHT can also provide 400G QSFP-DD FR4 transceivers based on 4 lanes of 100G PAM4, which together with GIGALIGHT’s 8-lane long-reach transceivers build the company’s foundation for next-generation metro telecommunications and metro DCI interconnects.
