Hi all,
If you were asking which is the main role of the optical layer, here is your answer :)
The optical layer is the agile photonic layer which has multi-degree wavelength cross-connect capacity and therefore provides the ability to reroute wavelengths to speed up service delivery and reduce the cost of O-E-O conversion.
That's all, I welcome everyone to leave a message and exchange in the comment area!
Thank you！
