EMLT-1550-ER series are high-performance laser transmitters for Head End applications with HFC/RFOG/FTTH networks. EMLT-1550-ER transmitters incorporate an high quality external modulator, narrow linewidth DFB laser and pre-distortion circuit which allows a transmission range of 80 km, while maintaining a high CNR level and excellent CSO and CTB performance. With an internal phase modulator that broadens the laser linewidth, the launch power level can be adjusted up to +18.5 dBm for extended distance of transmission of 80km in single mode fiber. The EMLT-1550-ER transmitters can support 77 NTSC analog channels. Designed to be digitally ready, the transmitters can also be loaded with QAM modulated data and HDTV channels. They are available in output power level of: +6 dBm, +8 dBm and +9 dBm. Features:
- Designed for Head End applications
- Transmission range to 80km
- DFB laser & external modulator
- SBS level can be set to +18.5dBm
- Single output port
- Excellent CSO, CTB, CNR
- Automatic Gain Control (AGC) and Manual Gain Control
