External Optical Transmitter

ET1550 external modulation optical transmitter products are new high-performance 1550nm external modulation CATV optical transmitter.

Product Details

Overview

ET1550 external modulation optical transmitter products are new high-performance 1550nm external modulation CATV optical transmitter. The transmitter is 1U height, can be easily installed in the 19 "rack. ET1550 transmitter for the 1550 wavelength dual 7dBm light output, the output signal spectral line narrow, in the long-distance transmission, even more advantages. The main device using JDUS, Fujitsu, MITSUBISHI DFB low noise, narrow linewidth, continuous wave laser and JDUS, AVANEX CATV high linearity external modulator with thermoelectric cooler. As the key components adopt the international brand and our company system optimization control technology, so that the machine's technical performance indicators fully meet the standards of similar imported equipment for cable television and telephone communications, it can provide high-quality images, digital or compressed digital signal long-distance transmission.


Features

 ◆ High quality: original system optimization control technology, RF predistortion technology to ensure excellent performance in the case of CNR system to obtain the largest CTB, CSO and SBS indicators.

 ◆ Flexibility: Phase modulation technology of the external regulator to maximize the performance of the system CSO, to maximize the fiber into the optical power to obtain long-distance transmission, and SBS threshold 13,16,18 field adjustable , Can be applied to different network transmission.

 ◆ Reliability: 19 "1U standard rack, built-in high-performance dual switching power supply, can be 85 ∽ 2665ac city network voltage in the hot backup work, MS-level automatic switch; chassis cooling can be automatic temperature control.

 ◆ Intuitive: external modulator and laser is the most expensive device, the machine set up a microprocessor outside the tune and the working state of the laser is monitored, and the operating parameters are displayed by the panel LCD window.

 ◆ Network management: option status monitoring transponder to ensure compliance with the national standard and compatible with the SCTE HMS standard, can achieve network management monitoring.
