NHNXT50U-B Series External Modulated Optical Transmitter
1550nm external modulation laser transmitter product is a new type of high-performance 1550nm external modulation optical transmitter. 1550nm transmitter is the 1550 dual-wavelength XXdBm optical output, the output signal spectral lines is narrow, more advantages in the long-distance transmission.
2.1 Both the external modulator and laser are imported from the United States or Japan.
2.2 Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
2.3 Perfect SBS suppress circuit and adjustable SBS in 13～19dBm，suitable for different types of CATV net.
2.4 AGC control.
2.5 Internal double power which can be changed automatically.
2.6 Automatically shell temperature control.
2.7 Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
2.8 The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
