The QAMnet EMLT-1550-FH series of digital laser transmitters are designed for carrying analog and QAM modulated digital channels for the SCTE next generation Fiber To The Home (FTTH) requirements. The EMLT-1550-FH series transmitters are a cost-effective and versatile transmission solution for RFoG/FTTH networks regardless of architecture.

The EMLT-1550-FH transmitters incorporate a zero-chirp external modulator and pre-distortion circuit which allow a 65 km transmission range, while maintaining a high OMI level and excellent CSO and CTB performance. The SBS launch power level is set to +13 dBm. EMLT-1550-FH transmitters can support up to 77 NTSC analog channels and since it is designed to be digitally ready, the transmitters can also be loaded with additional QAM modulated QAM and HDTV channels.
