TNZ5UNS4T51H Is Huawei OSN 1800 UNS4 Universal Line Board
            Huawei OSN 1800 UNS4 Board TNZ5UNS4T51H Overview
TNZ5UNS4T51H: 1 x 100G Universal Line Service Processing Board
Functional version of the UNS4 board: TNZ5
The TNZ5UNS4 board is a universal line board. It supports hybrid transmission of OTN, SDH and packet services with a maximum bandwidth of 100 Gbit/s. The UNS4 board processes and converts the received service signals into one OTU4 signal carried over an ITU-T G.694.1-compliant DWDM wavelength.
The TNZ5UNS4 board supports hybrid transmission of OTN, SDH and packet services, and functions such as Layer 2 switching, OTN ports, and SDH overhead processing.
