+9dBm 1-Output EM 1550nm ER Transmitter, Special Discount
The QAMnet EMLT-1550-ER series of laser transmitters are designed for use in HFC, deep fiber, RFOG and FTTH applications.
Overview
The QAMnet EMLT-1550-ER series of laser transmitters are designed for use in HFC, deep fiber, RFOG and FTTH applications. EMLT-1550-ER series are high-performance laser transmitters for head end applications with HFC/RFOG/FTTH networks.
The EMLT-1550-ER transmitters incorporate an external modulator and pre-distortion circuit which allows a standard transmission range of 80 km, while maintaining a high OMI 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 range of transmission, after EDFA amplification. The EMLT-1550-ER 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 QAM modulated data and HDTV channels.
