3091A
Outdoor Enclosure for 2991 L–Band Links
SATCOM
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.
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.
