Emerging technologies such as Artificial intelligence, autonomous vehicles etc. creates unprecedented bandwidth demand in a communication network. The 400g transceivers are already rolled out while there has been discussions around 800g and 1.6T. Underneath this, there is a revolution of pluggable coherent optics which continues to advance till date.
The coherent optical communication, at its most basic is a method that uses modulation of amplitude and phase of the light and transmission across two polarizations so that more information can be carried through same fibre optic cables. The main technology involves coherent modulation and heterodyne detections and coherent optics are the product based on this.
The primary use-cases are
- 5G fronthaul – midhaul – backhaul
- Datacentre interconnects
- Metro core – aggregation
- Longhaul – Subsea
The key benefits includes
- reduction of power usage
- reduction in DC rack space utilization
- maximize the fibre capacity
- reduction in overall capex/opex
