NY15D Series – 1550nm Microwave DFB Laser Diode
- NY15D series DFB laser diode is a directly modulated DFB laser that provides exceptional performance for linear fiber optics communications in very wide bandwidth applications. NY15D’s linear fiber optic lasers are an excellent alternative to using coaxial cable systems to transmit 12 GHz or 18 GHz signals. They offer significant improvements in the reliability of microwave communications networks by transmitting the RF signal in its original format. As a result of these properties, laser products provide significant improvements in signal quality for a wide variety of applications including antenna remoting, telemetry, timing, reference signal distribution, measurement, and delay lines.
- The 1550nm laser diode built-in optical isolator, TEC, thermistor, laser diode chip, and monitor photodiode are hermetically sealed in a 7PIN butterfly package.
