With a weather-tight seal and all the necessary internal connections and mounting hardware, these ODU’s may be placed directly at the antenna to provide greater flexibility in design.

Further, these power supplies are redundant, hot swappable and monitored with a summary alarm, so if one fails the facil- ity staff can replace it and still maintain 100% signal availability. The individual transmit- ters and receivers also are hot swappable, thus can be replaced or reconfigured without upsetting any of the other RF paths. |
