zenith R H
 zenith r

ZENITH R / R H is compact, easy to deploy and low cost microwave radio relay link especially designed for lastmiles. It is suitable for building LAN, MAN and WAN networks. ZENITH R use channel bandwidth up to 56 MHz, modulation scheme up to 256 QAM and transmission capacity is up to 360 Mpbs full duplex. ZENITH R H use channel bandwidth up to 112 MHz, modulation scheme up to 4096 QAM and transmission capacity is up to 1Gbps with possibility of asymmetric channels

The link operates in freebands 17 or 24 GHz with TX power range from -30 to +10 dBm. It has to be operated according to local regulations in each country.

The whole equipment is built in outdoor unit (ODU). The ODU is integrated with antenna to one compact system. The ODU has automatic polarization detection and several methods for service access including USB or WiFi connection.

The ZENITH ODU contains Gigabit Ethernet interface for user data and SFP port for optical fiber connection. The ODU and protected terminal box/PoE are interconnected via S-STP Cat.7 cable which is used both for power feeding and user interfaces. Also separated power feeding is possible via DC input.

The link supports Automatic transmit power control (ATPC) and Adaptive coding and modulation (ACM). Together with great sensitivity, high output power and antennas with high gain it makes the link determinated for high quality connections under all weather conditions.

Fast and responsive web interface and possibility to set up the link by SSH or Telnet makes the deployment extremely fast. Also the other integrated features like a automatic polarization detection, spectrum analyzer, console, USB/WiFi connection makes the maintenance much easier.
