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