+8dBm DM 1550nm SR Transmitter
The QAMnet DMLT-1550-SR series laser transmitters are reliable and costeffective for use in HFC, RFoG, FTTH and deep fiber applications. It is designed for networks with transmission distance up to 10 km.
Overview
The QAMnet DMLT-1550-SR series laser transmitters are reliable and costeffective for HFC, RFoG, FTTH and deep fiber applications. The DMLT-1550-SR uses a highly linear DFB laser module and an advanced predistortion RF drive circuit to deliver 50 dB of CNR, while maintaining optimal CSO and CTB distortion specifications.
The DMLT-1550-SR has a standard transmission range of 10 km. Since the transmitter operates at 1550 nm wavelength, the output signal can be easily amplified by an EDFA to extend the transmission range. The DMLT-1550-SR transmitters support up to 75 NTSC analog channels and since they are designed to be digitally ready, they can be loaded with 60 additional QAM modulated signal channels.
