Performance Highlights

EMCORE’s Model 3091A Outdoor Enclosure (ODU) provides power

and environmental protection for up to four 2991 transmitters or

receivers. 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.

Board

Two AC to DC power supplies drive the four transmitters or receivers and

provide enough additional current for four LNB’s. 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.
