Teko Telecom Digital Donor Front End Module (TDFE) provides the single-band/single-operator RF interface towards the signal source: it is connected to a Donor Antenna picking-up the signal from distant macro cell towers.

Modular Off-air Repeaters can be set-up by proper combination of Digital Donor Front Ends and Service Front Ends (our RF interfaces towards Service Antennas).

Digital Donor Front End Modules can also be used to drive Optical Systems: a Donor Antenna picks-up the signal and the Optical System acts as a repeater with distributed Service antennas connected to the Remote Units.
