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 |
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.
