English to German Tech/Engineering Patents METHOD AND DEVICE FOR PROCESSING FAILURE OF MULTI-SPAN WORKING CHANNEL IN RING OPTICAL TRANSMISSION NETWORK

The OTN is a transport network which is on the
basis of the wavelength division multiplexing technology
and in the optical layer organization network, and is the
next generation backbone transport network. For the
OTN, since the rate of the transmitted signals is higher,
the amount of carried information is larger, and the wavelength/
sub-wavelength service scheduling capability is
provided, thus network protection of the OTN becomes
more important for traditional network protection, and the
protection capability is also stronger
