Function and Feature Description Basic functions Supports conversion of the following signals: 80 x ODU0/80 x ODUflex/40 x ODU1/10 x ODU2/10 x ODU2e/2 x ODU3/1 x ODU4<,->,1 x OTU4 Supports hybrid transmission of ODU0, ODU1, ODU2, ODU2e, and ODUflex signals. Cross-connect functionality Implements the following service grooming when working with cross-connect boards: 80 x ODU0/ODUflex, 40 x ODU1, 10 x ODU2/ODU2e, 2 x ODU3, 1 x ODU4. OTN function Supports OTU4 interfaces on the WDM side. Adopts the frame formats and overhead processing methods defined in ITU-T G.709. Supports the SM function at the OTU4 layer. Supports the PM and TCM functions at the ODUk (k = 0, 1, 2, 2e, 3, 4, or flex) layer, and non-intrusive monitoring of PM and TCM overheads. WDM specifications Supports ITU-T G.694.1-compliant DWDM specifications. Tunable wavelengths Tunes the optical signals output on the WDM side within the range of 80 wavelengths in C-band at a 50 GHz channel spacing. TNZ5UNS4 is a 1-port 100G universal line service processing board applied to Huawei OSN 1800V. The UNS4 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 UNS4 board supports hybrid transmission of OTN, SDH and packet services, and functions such as Layer 2 switching, OTN ports, and SDH overhead processing. One UNS4 board supports hybrid transmission of OTN, SDH and packet services with a maximum bandwidth of 100 Gbit/s. Functions supported by the UNS4 board vary depending on the signals received.
