GIGALIGHT will Share the Latest R&D Results of 400G Silicon Optical Transceivers at CIOE 2021

Shenzhen, China, August 5, 2021 − Invited by the CIOE conference, GIGALIGHT will share the technology exploration fruits of silicon optical transceivers at the Optical Transceivers & Silicon Photonics Forum of CIOE 2021 on September 2 and will demonstrate a 400G QSFP DD DR4 silicon optical transceiver at GIGALIGHT’s booth at CIOE exhibit.
It is almost a definite situation that Silicon Photonics 400G transceivers will enter in the Internet industry. Since 2020, several manufacturers have announced their successful research and development of silicon optical transceivers. GIGALIGHT has tested many silicon optical transceiver products, including its self-developed 400G DR4 and items from the competing brands, the testing results are all good. Meanwhile, GIGALIGHT also compared the results with that of the the 400G DR4 optical transceiver based on EML TOSA synchronously, those study data will be all opened to public on CIOE Optical Transceivers & Silicon Photonics Forum.
As early as 2016, GIGALIGHT cooperated with CFOL to promote the silicon optical business, and also undertook the major project of the Shenzhen Municipal Government focusing on the development of silicon optical chips. However, the project process was affected by the patent issue with US later. GIGALIGHT didn’t stop its step to explore the new technology due to the incident, but grows to a more powerful and mature enterprise under great pressure. Now, the development of Silicon Photonics is just unfolding, and the brighter future needs the joint effort of all industry participants!
GIGALIGHT will release a series of silicon optical products that can be mass-produced after 2022 successively, including:
  • 100G QSFP28 DR1
  • 400G QSFP DD DR4 lite /DR4/DR4+
  • 800G QSFP DD DR8
  • 800G OSFP DR8


As the open optical network device explorer, GIGALIGHT integrates the design, manufacture and sales of active & passive optical devices and subsystems. The main products are optical transceivers, silicon photonics transceivers, liquid cooling transceivers, optical passive components, AOC & DAC, coherent optical modules and open DCI BOX subsystems. GIGALIGHT is a hardware solution provider of innovatively designed high-speed optical interconnection that focuses on data center, 5G carrier network, metro WDM transmission, UHD broadcast video and other application fields.
