SDH Radio


Pardis DRS-1600 SDH (Synchronous Digital Hierarchy) Microwave Radio System is designed to provide high quality SDH radio network. It can operate in frequency bands from 7.7 to 8.2 GHz. This SDH Radio transmits one STM-1/OC 155 Mbit/s signal plus optional wayside signals. This product includes two powerful interface units to convert/mux other data format such as Ethernet (4Mbps), ASI, E3,and Up to 4×E1 to STM1 data format and long as 2×OW, 6×Tel, 2×Service Channels to an E1 signal interface. The most efficient modulation techniques are used in full compliance with standard RF channel spacings as recomended by ITU-R.
