  IMOT-1550T series 1550nm optical transmitter is a top-class type of CATV optical transmitter. The height of the transmitter is IU, it can be mounted on the 19” frame conveniently. The main devices adopt Ortel, MITSUBISHI DFB low noise which contains thermoelectric refrigerator, continuous wave laser. The whole technical performance indexes reach the similar imported equipment standard, supplying quality long distance transmission of images, figures or compressed digital signal to cable and telephone communications.


  • Dual Power supply and AGC function as standard features.
  • High quality: Original system optimal control technology, RF driving amplifier and controlling circuit to make system getting optimal CTB, CSO and CNR indexes.
  • Reliability: The 19 “1U standard rack, built-in high-performance switching power supply, it can work at 85~265Vac MS level automatic switch, chassis cooling can be automatic control by temperature.
  • Intuition: Laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, and the panel LCD window displays the operating parameters.
  • Network management (Optional): RS232 port for local management and monitoring, RJ45 port for remote control and management.
