Deskripsyon ng Produkto*
LK-NYSD laser is a compact, directly modulated DFB laser designed for superior performance in linear fiber optic communication systems. It is capable of emitting wavelengths at 1310nm, 1550nm, and CWCM. These lasers serve as a superior substitute to coaxial cable systems for transmitting signals at 12 GHz or 18 GHz frequencies.
It enhance the reliability of microwave communication networks by preserving the integrity of the RF signal during transmission. Due to these characteristics, this laser products significantly boost signal quality across a broad spectrum of applications, such as antenna remoting, telemetry, timing and reference signal distribution, and measurement and delay lines.
LK-NYSD laser features an integrated optical isolator, thermoelectric cooler (TEC), thermistor, laser diode chip, and monitor photodiode, all of which are sealed within a 7-pin butterfly package to ensure hermetic protection.
