TNZ6UNQ1 is a 4-port 2.5G universal line service processing board applied to Huawei OSN 1800 II Enhanced, OSN 1800V. The UNQ1 board is a universal line board that supports hybrid transmission of OTN (ODU0, ODU1), SDH (STM-16) , and packet services with a total bandwidth not exceeding 10 Gbit/s. It can also receive and transmit only one or two types of services. The UNQ1 board processes and converts the received service signals into four OTU1 signals, which are carried over four ITU-T G.694.1-compliant DWDM wavelengths.

Tech Specs
