  • Apparatus and method for transmitting optical signals through a single fiber optical network
    Patent number: 6839517
    Abstract: An apparatus for wavelength multiplexing optical signals, wherein the apparatus includes at least one optically conductive sleeve, at least one collimating lens positioned to receive a optical signal from the at least one sleeve, and at least one dichroic splitter positioned to receive the optical signal from the at least one collimating lens. A filter may further be positioned to receive the optical signal from the at least one dichroic splitter in order to further filter the optical signal. The apparatus for wavelength multiplexing is configured to provide optical isolation of at least 75 dB via the combination of the at least one dichroic splitter and filter elements.
    Type: Grant
    Filed: February 12, 2001
    Date of Patent: January 4, 2005
    Assignees: Agere Systems Inc., Triquint Technology Holding Co.
