HDS-26series
SAT-IF Direct Modulated Satellite Optical Transmitter Series
HDS-26S
Product description
AITC HDS-26S (original model: HDBS-3000TX) satellite L-Band optical transmitter can transmit 950~2600MHz L-Band analogue by receiving satellite aerial radio frequency head or SAT-IF. It reaches transmission of total transparency and high quality and long distance by optical fiber. Satellite L-Band up/down link.
Product feature:
1. Laser type: A type (cooling), B type (non-cooling) high linearity, optical isolated DFB laser optional.
2. TG optical transmitter (standard type), build-in AGC linearity amplifier.
3. TO optical transmitter (type optional), build-in no IF amplifier, VOH input allowed, suitable for VOH output 4. L-Band externally optical transmitter.
5. Perfect laser APC, ATC control electric, prove long lifetime and high reliable work.
Main application
1. Satellite L-Band building fiber distribution system
2. Ocean steamer satellite fiber distribution system
3. Satellite L-Band uo/down fiber link
HDS-26D
