Description
TNZ8NQ2 overview
TNZ8NQ2 is a 4*port 10G line service processing board applied to Huawei OSN 1800 II Enhanced, OSN 1800V.
The TNZ8NQ2 board is a line board that supports hybrid transmission of OTN services (ODU0/ODU1/ODU2/ODU2e/ODUflex) and packet data packets with a maximum bandwidth of 40 Gbit/s.
It also supports transmission of one or two types of services.
The TNZ8NQ2 board processes and converts the received service signals into four OTU2/OTU2e signals, which are carried over ITU-T G.694.1-compliant DWDM wavelengths.
