Our CWDM ring network solution consists of two core room and eight node rooms. It adopts the sixteen-channel CWDM system to build up the network. Every node has two CWDM systems that link to the two core switches respectively. Every node is adopted with a switch that has a main GE port and a standby GE port linking the two CWDM systems respectively. In case of the aging of optical cable, we still add an OEO repeater to a node to ensure the signals undistorted.

We also take the transmission capacity expanding into consideration. We preset a wavelength division channel in each node, so the user just need to add the various interface cards to achieve the goal.
