Summarize

TFT1550 direct modulation 1550nm optical transmitter is small size and compact, it combines with TNE1000 platform to consist excellent performance indoor transmission equipment.

TFT1550 direct modulation 1550nm optical transmitter adopts  high linearity, low noise DFB with optical isolator imported laser as optical source, using the company’s newly developed full-band predistortion circuit, significantly improved the laser’s  non-linear index. TFT1550 optical transmitter has built-in microprocessor to monitor all the  laser operating status parameters, and transmit to TNE1000 system controller through trunk. System controller’s intelligent function provides TFT1550  module good internal working environment, the VFD display on the platform can monitor its operating status. In this environment, TFT1550  module can play excellent performance, and has a very high reliability and stability.

TFT1550 direct modulation optical transmitter operating range is within 10km,the largest not more than 20km,the main application is cooperating with EDFA, it also supports the sub head-end edge IP QAM and local program insertion. 

Features:

·  Using famous brand and high reliability DFB laser, excellent link performance

·  1550nm Wavelength, standard ITU-T central wavelength

·  Excellent APC,ATC function, adapt wide range RF input, guarantee the laser stabile output power.
