QAMnet EMLT-1550-NC series of transmitters are designed for multiple-wavelength HFC, deep fiber, RFOG and FTTH applications. EMLT-1550-NC can be incorporated into forward path NarrowCasting (NC) solution for targeted digital services (VOD, IP, cable telephony). Digital bandwidth can be added to existing fiber infrastructure, by adding a new EMLT-1550-NC. EMLT-1550-NC can be custom ordered with 41 different DWDM wavelengths. Using Add Drop Module, multiple EMLT-1550-NC transmitters can be combined into a single fiber. Each EMLT-1550-NC can deliver various digital services to targeted recipient, via a specific wavelength. EMLT-1550-NC incorporates an external modulator and pre-distortion circuit to enable transmission distance of 65km, while maintaining high CNR and excellent CSO/CTB performance. Designed to be digitally ready, EMLT-1550-NC can be loaded with hundreds of QAM modulated data and video channels. Available in output power of +5 dBm, +6 dBm and +7 dBm. Features:
- Externally modulated technology at directly modulated price
- Laser wavelength can be selected to from 41 DWDM channels
- 65 km standard transmission range, can be extended to 90km
- Adjustable SBS suppression from +13 dBm to +16 dBm
- Fully compatible with QAM256 data and HDTV channels
- AGC (Automatic Gain Control) and Manual Gain control
