SDH RRE

RRE "Phlox"

Features and advantages:

• Use of a working range of frequencies in a strip of 2 or 4 GHz enables to provide the high quality of communication(connection) independent from meteo that is extremely important for climatic conditions of Russia.
• The station considers features of domestic conditions of operation: the built in system termo allows to work to the external equipment in conditions of low temperatures (up to-50 °).
• Essential advantage RRE "PHLOX" - work on greater intervals that is important for territories with the carried communication centers: up to 100 km for a stream 2-Mbit/s, up to 80 km for a stream 8-Mbit/s and up to 60 km for a stream 34-Mbit/s. We really maintain such lines.
• RRE "PHLOX" has digital service channel RS-232 which allows to connect to it system of the operative remote control - SOPEK, the NETWORK-SERVICE developed by firm.
