Product details
Product Description
The external modulation laser transmitter product is a new type of high-performance 1550nm external modulation optical transmitter. Transmitter is the 1U height, and can be easily installed in 19 "rack. This transmitter is the 1550 dual-wavelength 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 line width, continuous-wave lasers with thermoelectric cooling device made in JDUS, Fujitsu, MITSUBISHI and JDUS, 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.

Model Description
KW1550ET10: (Single fiber) 1*3dBm, 1*5dBm, 1*7dBm, 1*9dBm, 2*7dBm
KW1550ET20: (Double fiber) 2*5dBm, 2*7dBm, 2*9dBm

Product feature
1) 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 .
2) 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, 13,16,19, may apply a different network transmission.
3) Reliability: The 19 "1U standard rack, built-in high-performance dual switching power supply,it can work in the backup at 85 ∽ 265Vac City Network Voltage, MS-level automatic switching; chassis cooling automatic temperature control.
4) 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.
5) 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.
