Transmitter

OPT-1550E-S Series External modulation optical transmitter is a Standard type of high- performance 1550nm external modulation optical transmitter. It is especially designed for small or middle-size TV stations, CNR ≥51.50dB when tested in 59CH PALD, SBS set at 18dBm, point to point 50km fiber.
Mounted in standard 1U, 19’’ chassis, the output signal spectral lines is narrow, more advantages in the long- distance transmission. Key components adopt DFB low-noise, narrow line-width, continuous-wave lasers with thermoelectric cooling device made in JDSU, Fujitsu, MITSUBISHI and AVANEX 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.
