Narrowcast DWDM Transmitter

AT3520G and AT3535G


AT3520G and AT3535G series narrowcast DWDM transmitters are designed for QAM-modulated narrowcast digital services. Available in 40 DWDM wavelengths and enabling transmission of up to 80 256-QAM modulated channels per wavelength, these transmitters feature 10 dBm optical output power, programmable dispersion compensation, and user-selectable RF input gain stage on select models.  

These AT3520G and AT3535G transmitters may be used with either a single back plate or ARRIS's innovative four transmitter multiplexer back plates. BP-35M4x series mux back plates each eliminate four patch cords and the need to allocate internal chassis slots for dedicated multiplexer modules, while their pass-through DWDM input and output ports permit their cascading and sequential muxing of multiple individual ITU channels onto a single optical fiber.
