DT3515C
Series Digital Transmitters
(5-65 MHz RF input,
transmit at 3.1875 Gbps) |
The DT3515C Digital Transmitter digitizes two RF return paths (with 5–65 MHz
pass band), multiplexes them and transmits them at 3.1875 Gbps on a single return fiber
on a DWDM ITU grid wavelength. By providing two RF returns on an ITU grid wavelength, the
DT3515C 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 DT3515C 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
multiplexer module.
The high density packaging enables network operators to install 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.
