Latest Patents

Fransisco's latest patents include a bi-directional long haul/ultra long haul optical communication link. This invention employs a bi-directional configuration to implement a hybrid ultra long haul (ULH) and long haul (LH) optical transmission system. The link carries ULH channels and LH channels in opposite directions across different bands. Raman amplification is utilized for the ULH band, while Erbium-doped fiber amplification (EDFA) is used for both the LH and ULH bands. Optical circulators are employed for multiplexing and demultiplexing, providing excellent isolation between the ULH and LH channels without incurring the ripple penalty of prior art solutions.

Another significant patent is the low noise figure optical amplifier for DWDM systems with per sub-band power control. This invention provides improved systems and methods for optical amplification of WDM signals. Multiple sub-bands of a WDM signal are amplified in a first common amplification stage and then separated. The separated sub-bands are amplified by independent parallel amplification stages, each equipped with its own optical pump energy source. This architecture allows for low noise figures and independent power regulation for each sub-band while minimizing space requirements and costs.
