NYDMT Series UWB Directly Modulated Transmitter
NYDMT transmitters are mainly composed of high-speed directly modulated DFB laser, automatic optical power control circuit, automatic temperature control circuit, voltage-stabilizing conversion circuit, monitoring and indicating circuit.
The wavelength of NYDMT is optional (DWDM ITU standard). Its modulation bandwidth is better than 18GHz, output power can reach 10mW. A single positive power supply can make NYCMT work stably in the voltage range of +7V ~+36V. NYDMT takes many advantages, such as low relative intensity noise, good stability of output wavelength, high output power, etc.
Besides, the NYDMT Transmitter has the indicating function, which shows whether the power supply and optical power output are normal or not.
