High Power, 1550nm Directly Modulated Transmitter, Wide 20km Range, +15dBm
Optilab LT-1-DM-1550-HP series high power laser transmitters are cost effective, space saving solutions designed for HFC, FTTH and deep fiber applications. The LT-1-DM-1550-HP uses a highly linear, low chirp DFB laser module and advanced pre-distortion RF circuit to deliver 50 dB of CNR, while maintaining optimal CSO and CTB distortion specifications. The output power level is amplified by an internal EDFA to up to +23 dBm.
The LT-1-DM-1550-HP has transmission range up to 20 km. LT-1-DM-1550 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 LT-1-DM-1550-HP is available at these output power levels: +15 dBm, +18 dBm, +20 dBm and +23 dBm.
