Example
MODULE FOR OPTICAL INTERCONNECT
This module is a new ultra-thin pluggable active optical cable with a Silicon-Photonics chip for optical interconnects that are used in places like data centers. It has achieved 100 Gbps of data transmission over distances of up to 300 m and thus enables long-distance transmissions at exceptionally high-speeds. The module can solve the bottleneck problem of data transfer loss in electrical wiring and handle the strong demands of high bitrate datalinks.
Benefits of quantum dot lasers
- Stable operation at
high temperatures and
optical feedback tolerance - The superior high-temperature stability and optical feedback tolerance of quantum dot lasers make them ideal light sources for silicon photonics.
