Whether the ETMXS board is a 2.5G board

3

The ETMXS board is an OTU. The four STM-16/OC-48/OTU1 optical signals received on the client side are multiplexed into one OTU2 signal. The board can concurrently receive two types of services and convert the received optical signals into optical signals carried over a standard wavelength compliant with ITU-T G.694.1.
