DT3515
Series Digital Transmitters
(5-42 or 5-50 MHz RF input,
transmit at 2.125 Gbps) |
The DT3515 Digital Transmitter digitizes two RF return paths (with models
supporting 5–42 and 5–50 MHz pass bands), multiplexes them and transmits them on a single
return fiber on a DWDM ITU grid wavelength. 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.
The unique mid-plane packaging of the DT3515 features two back plate options:
a compact one-module width design for single wavelength applications (using optional back
plate model BP-A6) or an integrated ''Back Plate'' multiplexer for DWDM applications
(using optional back plate model BP-35M4x-1-02-AS) which eliminates the need for a separate
platform or shelf for a typically packaged multiplexer.
The high density packaging enables network operators to intall up to 12
transmitters per 3RU chassis, all of which can be monitored remotely or locally from the
power supply module. The compact design minimizes rack space requirements in hubs.
