1550nm Directly Modulated Transmitter, Standard 10km Range, +6dBm
The Optilab LT-1-DM-1550 series laser transmitters are a reliable and cost-effective solution for HFC, RFoG,
PON, and deep fiber applications. Using a dispersion compensated analog 1550 nm DFB laser module and an
advanced pre-distortion RF drive circuit, LT-1-DM-1550 transmitters deliver 50+ dB of CNR while maintaining
high CSO, CTB performance. Available in a Standard Reach (SR) option with a standard transmission range of
20 km, or an Extended Reach (ER) option with a transmission range of 40 km, the LT-1-DM-1550 is the best cost/
performance ratio in the industry. The LT-1-DM-1550 series is available with output power levels from +6 dBm
to +10 dBm, and the 1550 nm wavelength can be easily amplified by any EDFA. Designed to be digitally ready,
it can be loaded with 77 NTSC analog channels with an additional 60 QAM channels. Contact Optilab for more
information.
