The MO-E is a 1.2 GHz optical node built-up using the Comtech shell system. The device provides 2 splittable high-level outputs as well as the possibility for using 2 upstream transmitters. Thanks to the fully electronic alignment based on the display and keyboard integrated in each node, installation is very quick and easy. The reverse path RF signal ways are selected automatically depending on whether 1 or 2 transmitter modules are installed. Cost efficiency and felixibility were important aspects of the design, so the options are implemented as independent modules, accordingly the ingress control switches don't require the presence of a monitoring transponder
