SUZHOU, China, March 10, 2020 /PRNewswire=KYODO JBN --

Hengtong Rockley Technology Co., Ltd. announces the release of a 400G QSFP-DD DR4

optical module based on Silicon Photonics technology for the next-generation data centenetwork. Hengtong Rockley will have a live demo from March 10th to March 12th, 2020

at the OFC exhibition in San Diego, CA, USA. The new 400G QSFP-DD module is the

first  400G Silicon Photonics optical module product revealed by Hengtong Rockley.

The DR4 optical module will be used in next generation Cloud-scale datacenter networks

for the connection between switches as a low-cost, low-power consumption optical

connection solution. The deployment of 400G transceivers enables datacenter networks to

deliver a 4x increase in network speed compared to existing deployments using 100G.

Hengtong Rockley's 400G QSFP-DD DR4 module uses the industry's most advanced

7nm DSP chip. The optical chipsets, that form the key building blocks of the transceiver,

are from Rockley Photonics, Ltd., which will also live-demo their Silicon Photonics TX and

RX PIC chipsets used in the Hengtong Rockley 400G DR4 transceiver in their booth at OFC.

Rockley's Silicon Photonics technology not only integrates the passive and active optical components, to greatly reduce the need for optical sub-assembly, but also introduces

a special design to ease fiber coupling. As a result of the automated passive alignment process

for light sources and fiber arrays, the manufacturing process for the optical module has been

simplified and made suitable for mass production.

Hengtong Rockley Technology Co., Ltd. is a joint venture established by

Hengtong Optic-Electric Co., Ltd., China and Rockley Photonics Limited, UK.

Hengtong Rockley designs and manufactures high-end optical modules. It is also

committed to the design of Silicon Photonic chips and their integration, packaging,

and testing, for improved competitiveness of optical module design and manufacturing.
