  • Transamplifier, system and method for amplification of optical signals at plural wavelengths
    Patent number: 8265490
    Abstract: Disclosed herein are embodiments of a device, method of use and system for an analog multi-wavelength transamplifier. The transamplifier embodiments described herein allow the use of multiple wavelengths to segment logical service groups, such as for use in a CATV distribution system and a FTTH system having a broadband overlay. Improved optical signal power performance can be achieved by using direct modulating transmitters and maintaining polarization of the optical signals that are modulated by a phase modulator, such as an external waveguide.
    Type: Grant

  • Amplified wavelength broadband video distribution architectures using a phase modulating waveguide
    Patent number: 7903980
    Abstract: Provided herein are embodiments of a device, method of use and system for a low-cost analog multi-wavelength video distribution transamplifier for CATV and FTTH networks having a broadband overlay. The transamplifier embodiments described herein allow the use of multiple wavelengths to segment logical service groups in a CATV distribution system and a FTTH system having a broadband overlay. Improved optical signal power performance can be achieved by using direct modulating transmitters and modulating the optical signal for with an external waveguide, thereby decreasing SBS and reducing non-linearities.
