NYSD Series Mini UWB DML Laser Module
- NYSD series module is a mini directly modulated DFB laser that provides exceptional performance for linear fiber optics communications. It can provide wavelengths of 1310nm, 1550nm, and CWCM.
- NYSD series lasers are an excellent alternative to using coaxial cable systems to transmit 12GHz or 18GHz 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 applica tions including antenna remoting, telemetry, timing, reference signal distribution, measurement, and delay lines
- NYSD series laser built in optical isolator, TEC, thermistor, laser diode chip, and monitor photodiode are hermetically sealed in a 7PIN butterfly package.
