Note： In the the condition of stipulated link-loss, configurate 59 PAL-D analog television channel signals within 550MHz frequency, in the range of 550MHz ~ 862 MHz frequency transmit digital modulation signals, digital modulation signal level ( in 8MHz bandwidth) is 10dB lower than the analog signal carrier level,when the optical input power is 0dBm, you can measure the carrier combination triple beat ratio (C / CTB), carrier combination of second-order beat ratio (C / CSO) and the carrier to noise ratio

Product Overview

Overview

ZP-OT-1550S 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. The main devices adopt DFB low-noise, narrow linewidth, continuous-wave lasers with thermoelectric cooling device made in AOI, EMCORE,Fujitsu and MITSUBISHI, JDSU CATV high linearity external modulator. Because of the international brand adoption of key components and our company system optimization control technology, SMNP network control technology, the machine’s technical performance indicators fully measure up the standard of similar imported equipment , it can provide high-quality images, digital or compressed digital signal long-distance transmission for cable television and telephone communications.

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, machineequipped 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 plugtype of switching power,which is beneficial to heat dissipation and replacement,and dual power supply cold and hot backup.
