Metro optical networks interconnect a wide range of traffic from central offices and data centers within a metropolitan area. The complex metro networks typically cover ranges from 80km to 1,000km. Long haul networks link major population centers within continents with spanning distances typically from 1,000 km to more than 2,500 km.
ROADM is an innovative way to provide a direct optical routing between the senders and receivers. The traffic does not go into any intermediate core switches. The optical signal can just go through to a ROADM ring. If the node is not the destination, the wavelength will be routed to a pre-set exit port. If the optical signal arrived the desired nodes, the WSS can drop that wavelength and connect to the corresponding transceiver. So, there is no more delay in the transmission path.
The wavelength selective switches are equipped with the
advance Liquid Crystal on Silicon (LCoS) technology. The granular
spectrum can be as low as 6.25GHz and it supports all transmission
data rates from 10Gb/s, 100Gb/s, 400Gb/s or super-channels in
order to improve the spectral efficiency and lower the running cost.
The WSS comes with single or twin within a module supports from 9 ports, 20 ports and up to 35 ports. They are colorless/directionless (CD) to extend their network flexibility, meet route-and-select configurations which allow drop-path filtering and improve port isolation.
