Product Description
LK-NY30E Series Ka-Band Optical Transmitter is primarily made up of several key components, include high-power laser light source, ultra-wideband LiNbO3 intensity modulator, voltage stabilization conversion circuit, driving circuit, monitoring and indication circuit.
This transmitter operates within the ITU-standard dense wavelength division multiplexing (DWDM) spectrum for its modulated optical signal output. It boasts a modulation bandwidth that exceeds 35GHz and is capable of producing an output optical power of up to 10mW, with a stable output light wavelength.
LK-NY30E Series operates on a single positive power supply voltage, maintaining robust performance within a voltage range from +12V to +36V. Additionally, the transmitter is equipped with an integrated indication function that provides real-time feedback on the status of the power supply and optical power output, ensuring reliable operation and ease of monitoring.
