+9dBm 1-Output EM 1550nm Transmitter, +16.5dBm SBS
The QAMnet EMLT-1550-ER series of laser transmitters are designed for use in HFC, deep fiber, RFOG and FTTH applications with a standard range of 65 km.
Overview
The QAMnet EMLT-1550-SR series laser transmitters are designed for use in HFC, RFoG and FTTH applications. The EMLT-1550-SR series transmitters are a cost-effective and versatile transmission solution for HFC/RFoG/FTTH networks regardless of architecture.
The EMLT-1550-SR transmitters incorporate a zero-chirp external modulator and pre-distortion circuit which allow 65 km of transmission range, while maintaining a high OMI level and excellent CSO and CTB performance. The launch power level can be adjusted from +13.5 dBm to +16.5 dBm. The EMLT-1550-SR 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 data or HDTV channels.
