The QAMnet DMLT-1550-SR series laser transmitters are reliable and cost-effective for use in HFC, RFoG, FTTH and deep fiber applications. DMLT-1550-SR uses a highly linear DFB laser module and an advanced pre-distortion 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.
DMLT-1550-SR transmitters support up to 75 NTSC analog channels. Designed to be digitally ready, they can be loaded with 60 additional QAM modulated signal channels.
The DMLT-1550-SR is available at three output power levels: +6 dBm, +8 dBm and +10 dBm.
Features:
- Highly linear, analog-modulated 1550 nm DFB laser source
- Advanced pre-distortion circuit minimizes CSO and CTB distortion
- Optional Automatic Gain Control (AGC) for optimal RF drive level
- 75 channel NTSC plus 60 digital channels loading plan
- -20 dB front panel RF test port
- LED front panel digital display and status indicators
- 45-870 MHz modulation bandwidth
