The QAMnet EMLT-1550-NC series of laser transmitters are designed for multiple wavelength systems for HFC, deep fiber, and FTTH applications. The EMLT-1550-NC series transmitters can be incorporated into a forward path narrowcasting system specifically for targeted digital services (VOD, IP, cable telephony). Digital bandwidth can be incrementally added to existing fiber infrastructure by adding a new wavelength.

The EMLT-1550-NC transmitters can be custom ordered with 41 different wavelengths. Using a DWDM combiner, multiple EMLT-1550-NC transmitters can be combined with a standard laser transmitter into a single fiber. Each transmitter can deliver various digital services to a targeted recipient, via a specific wavelength laser. The EMLT-1550-NC transmitters incorporate an external modulator and pre-distortion circuit which allow the transmission range to be extended up to 80 km, while maintaining a high OMI level and excellent CSO and CTB performance. The launch power level can be adjusted from +13 dBm to +16 dBm.
