High Power DAS Remotes Units


DDH Series, Remote Units are high performance wideband amplifiers. An industry leader in DAS solutions, the Bird fiber optic system allows controlling a mixture of remote families (DDH & DDR) from a single Master Unit to reduce the head end footprint and maximize usage of the fiber backbone infrastructure. Multiple frequency bands and amplifiers can be contained in a single chassis.

Key Features
  • Able to mix amplifier types in a single remote housing
  • Radio access technology agnostic
  • Multi-operator
  • WDM, CWDM and non-multiplexed options
  • True receive diversity and MIMO options
  • Completely software monitored and controlled
  • Wide band amplification
  • External DB-9 alarm connection
  • RoHS compliant
