Product Description
LK-NY15T Transmitter is primarily made up of several key components, include high-speed directly modulated Distributed Feedback (DFB) laser, circuit for automatic optical power control, circuit for automatic temperature control, voltage-stabilizing conversion circuit, and monitoring and indication circuit.
This transmitter operates at a wavelength of 1550nm and has a modulation bandwidth that exceeds 18GHz, with an output power capable of reaching up to 10mW, while maintaining a stable output wavelength. It is powered by a single positive power supply, which ensures stable operation across a voltage range from +7V to +36V.
Additionally, LK-NY15T Transmitter is equipped with functions that indicate the normal status of both the power supply and the optical power output, providing users with intuitive operational feedback.
