Aurora's DT3515 series Digital Transmitters digitize two RF return paths, multiplex them, and transmit them on a single return fiber on a DWDM ITU-grid wavelength. Models supporting 5–42 and 5–50 MHz passbands (DT3515) transmit the signal at 2.125 Gbps, while models supporting a 5–65 MHz passband (DT3515C) transmit the signal at 3.1875 Gbps.
By providing two RF returns on an ITU-grid wavelength, the DT3515 alleviates fiber exhaustion and greatly simplifies the network by enabling the use of DWDM transport from hubs to the headend. The 5 dBm output transmitter power supports link losses up to 23 dB and 200 km dispersion limits.
