Overview

  MIC-OT-1550 externally modulated optical transmitter product is a new type of high-performance 1550nm external modulation CATV optical transmitter.Transmitter is the 1U height,and can be easily installed in 19"rack.transmitter is the 1550 wavelength 7dBm or 9dBm optical output,the output signal spectral lines is narrow,more advantages in the long-distance transmission.

Features

  ●High quality:original system optimization control technology and RF pre-distortion technology ensure that the system can acquire the maximum CTB,CSO,and SBS targets in the case of excellent performance CNR.

  ●Flexibility:In ensuring the high performance system CSO,the phase modulation technology of external modulator maximize the optical power into the fiber in order to obtain long-distance transmission,and the field adjustable SBS threshold,16,17,18,may apply a different network transmission

  ●Reliability:The 19"1U standard rack,built-in high-performance dual switching power supply,it can work in the backup at 90~265Vac City Network Voltage,MS-level automatic switching;chassis cooling automatic temperature control.

  ●Intuitive:The laser is the most expensive machine components,machine equipped with microprocessor monitors the working state of the laser,the panel LCD window displays the operating parameters.

  ●Network type:Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard,it enable network management monitoring capabilities.

  ●Plug type of power:Use the aluminum structure plug type of switching power,which is beneficial to heat dissipation and replacement,and dual power supply cold and hot backup.
