ROF-DML analog broadband direct light transmission module direct modulated laser Modulator

Short Description:

ROF-DML series analog wideband direct-modulated optical emission module, using high linear microwave direct-modulated DFB laser (DML), fully transparent working mode, no RF driver amplifier, and integrated automatic power control (APC) and automatic temperature control circuit(ATC), This ensures that the laser can transmit microwave RF signals up to 18GHz over long distances, with high bandwidth and flat response, providing superior linear fiber communication for a variety of analog broadband microwave applications. By avoiding the use of expensive coaxial cables or waveguides, the transmission distance limit is eliminated, greatly improving the signal quality and reliability of microwave communication, and can be widely used in remote wireless, timing and reference signal distribution, telemetry and delay lines and other microwave communication fields.
