A colorless WDM-PON system using multi-wavelength light sources for optically-injection-locked transmitters (original) (raw)

Optical Fiber Technology, 2010

Abstract

ABSTRACT We propose and demonstrate a bidirectional wavelength-division-multiplexed passive optical network system by using multi-wavelength light sources to lock FP lasers in order to achieve a colorless WDM-PON transmission. In the proposed system, we configured multi-wavelength light sources in C and L bands to, respectively, lock the FP lasers at a subscriber site and a central office. The multi-wavelength light source for upstream FP lasers can improve the pump power budget for locking FP lasers. Compared with the conventional spectral slicing technique, the proposed configuration would save more than a half of optical pump power in achieving a colorless WDM-PON system.
