Deskripsyon ng Produkto*
LK-NYDMT Transmitter is primarily made up of several key components, include high-speed directly modulated Distributed Feedback (DFB) laser, automatic optical power control circuit, automatic temperature control circuit, voltage-stabilizing conversion circuit, monitoring and indicating circuit. This transmitter provides a variable wavelength in line with the Dense Wavelength Division Multiplexing (DWDM) ITU standards.
It offers a modulation bandwidth that exceeds 18GHz and can achieve an output power of up to 10mW. Operated by a single positive power supply, the LK-NYDMT Transmitter maintains stable performance across a voltage range from +7V to +36V. The transmitter is designed with several advantageous features, such as minimal relative intensity noise, excellent stability of the output wavelength, and a high level of output power.
Furthermore, LK-NYDMT Transmitter is equipped with an advanced indication function that visually confirms the status of both the power supply and the optical power output, ensuring that the system is operating within optimal parameters, this feature is essential for real-time system monitoring and for the swift identification of operational anomalies.
