40CH DWDM protection ring network

Application features: 

Hooosi proposes the unique DWDM ring network protection solution. The OLP dual transmission and selective reception mode in wavelength division end can ensure the protection for every service. It provide higher protection than traditional line end OLP protection. In traditonal case, if one OLP failed to switch, the whole network service will be affected. So the new protection not only protect the optical cable routine, but also protect the service of every channel. Thus it can greatly improve the protection for ring network.
