Iris(tm) is a channelizer and non-blocking reversible switch that uses optoelectronic processing technology to provide a small, low power package at a reasonable cost. It can operate on 10 to 50 signals, each composed of 100 to 500 FDM or CDMA voice grade channels and route these signals to the appropriate buffers for transmission.
In the receive mode, each incoming signal is channelized into voice grade channels. Those channels that are to be switched are extracted and routed. In the transmission mode, the storage buffers are routed back into the switch and the system produces multiple output signals in FDM or CDMA format at an intermediate frequency.
For FDM signals, a variety of filter shapes can be implemented including the raised cosine. For CDMA signals, the system can readily use Gold codes and codes of related families to reduce interference.
Iris(tm) has been under development for more than a year. Essex is actively seeking strategic partners to bring IRIS to market.
Call 800-53ESSEX and ask for the Iris(tm) Program Manager to discuss your application or special needs.
