What we do

Overview

Aliathon’s OTN solutions support all line rates, ODU containers and mapping schemes. Their fine-grained flexibility allows support for all types of clients from traditional TDM to 8B10B streams and packet interfaces (see ODU0 / ODUflex).  We support single and multi-channel options, spanning client rates from 1Gb -> 100Gbps with OTN line rates from OTU1 -> OTU4.
