Model 3091A Outdoor Enclosure

for L–Band Links using the 2991T/R

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 facility staff can replace it and still

maintain 100% signal availability. The individual transmitters and

receivers also are hot swappable, thus can be replaced or reconfigured

without upsetting any of the other RF paths.
