We are offering fiber optic transmitter power 6 dbm 14 dbm transmitters use directly modulated dfb technology for transmission of optical signal at 1310nm wavelength. A power-doubler amplifier with built-in agc circuit and dfb technology along with rf pre-distortion circuit have been incorporated to achieve excellent c/n, cso & ctb performance providing a stable rf signal power optic transmitters incorporate a thermo-electric cooler and auto control for laser power & bias current to ensure stable optic output power and longer life of laser module. features: agc/mgc for stable rf levellinear frequency responseexcellent c/n, cso & ctbhigh quality dfb fresh laserunique rf pre-distortion circuitstandard 19 inch rack mount typeoptic output power: 6dbm14dbm (4mw25mw)an intelligent microcontroller to control all parameterslcd display for displaying all transmitter parameters
