Abstract

Se divulgan sistemas, dispositivos y métodos para anti-recorte híbrido en enlaces ópticos en redes de fibra coaxial híbrida (HFC); se puede incluir un circuito anti-recorte híbrido en trayectorias tanto de enlace ascendente como de enlace descendente de la red HFC para evitar que el láser sea impulsado en el enlace óptico por encima de un umbral de recorte; el circuito anti-recorte puede comparar el promedio, o RMS, el nivel de potencia de entrada y la envoltura de potencia de una señal de entrada RF con un umbral de recorte asociado con el módulo láser particular que se esté utilizando; si la potencia promedio está por encima del umbral de recorte, entonces la señal de entrada puede ser atenuada en forma proporcional para evitar el recorte; si los picos en la envoltura de potencia están por encima del umbral de recorte, entonces la corriente de polarización del módulo láser se puede ajustar para evitar el recorte; por consiguiente, los modos de la operación del circuito anti-recorte incluyen la aplicación de atenuación a la señal de entrada y/o el ajuste a la corriente de polarización del módulo láser.
