TNF1LSC is a 1-port 100Gbit/s wavelength conversion board applied to Huawei 1800 I&II Compact, 1800 II Enhanced, OSN 1800V. The LSC board is a wavelength conversion board and applies to coherent systems. In the receive direction, the board receives one 100GE/OTU4 optical signal from the client equipment, maps the optical signal into an OTU4 signal, and converts the OTU4 signal into a standard WDM wavelength. TNF1LSCT75 1-port 100Gbit/s wavelength conversion board Applied to Huawei 1800 I&II Compact, 1800 II Enhanced, OSN 1800V Supports client 1+1 protection, intra-board 1+1 protection (when working with the OLP board) Supports the ALS function on the client side when client services are non-OTN services Supports ESC function Supports Optical-layer ASON when working with Z5UXCMS/Z2UXCL/Z8XCH
