GIGALIGHT Launches 400G QSFP-DD PSM8 Transceivers to Boost Data Center Parallel Solutions

Shenzhen, China, February 1, 2021 − GIGALIGHT, the advocate of data center parallel optics, today announced the launch of the industry-leading 400G QSFP-DD PSM8 transceivers for the optical interconnection requirements within 2km or 10km of data center 400G Ethernet and OTN, which made up for the distance problem of 400G SR8.
With the advent of the 5G era, more and more hyperscale data centers have emerged around the world, requiring the deployment of a large number of high-speed optical transceiver modules. As the mainstream technology of the previous generation, 100G has entered the mature and stable stage of its life cycle. The reduction of unit bit cost has been greatly restricted, and 400G technology has emerged as the times require. At present, three international standards organizations — IEEE, ITU, and OIF — have all released relevant 400G standards, and some of the top optical module suppliers have launched 400G optical modules for data centers.
GIGALIGHT’s newly launched 400G PSM8 modules are based on a unique parallel optical design. The inside of the module uses a single PCB design, which reduces the difficulty of attaching the board. The process is simple, easy to mass produce, reliable in process, and controllable in thermal design. The performance and power consumption are excellent, which is believed to be the leading level in the industry.
The main features of GIGALIGHT 400G QSFP-DD PSM8 optical modules are shown as following.
  • 8-lane parallel light engine
  • Dual rates of 400G Ethernet and OTN
  • Reach up to 2km or 10km
  • Uncooled 50G PAM4 EML lasers
  • High density design with good reliability
  • Low power consumption < 11W
  • Commercial operating temperature range of 0℃ to 70℃
The optical eye diagram and the key performance indicators of the receiver are shown as following.
The launch of GIGALIGHT 400G QSFP-DD PSM8 enriches GIGALIGHT’s 400G parallel data center interconnection solutions. GIGALIGHT is the main advocate of parallel data center technology and has invested and researched deeply in the field of parallel optical interconnection technology. The chairman of GIGALIGHT said, “We firmly believe that in the long run, parallel data centers are the best solution.” To this end, GIGALIGHT has launched the following series of parallel optical modules with a complete lineup.
GIGALIGHT’s Parallel Optics Family List is shown as following.
  • 40G QSFP+ SR4/AOC/PSM4
  • 100G QSFP28 SR4/AOC/PSM4
  • 200G QSFP56 SR4/AOC/DR4
GIGALIGHT will launch a 400G QSFP-DD DR4 parallel optical module based on silicon photonics technology in 2021 to further improve and enrich the company’s parallel solutions. The newly developed 400G QSFP-DD PSM8 modules have the basis of high reliability, low power consumption and mass manufacturing. We believe they will provide a solid interconnection foundation for data center and telecommunications users’ broadband upgrade.
