Patent number: 10404399Abstract: The differences in the power received from multiple optical network units connected to an optical hub may exceed an allowable dynamic range. The dynamic range may be reduced by determining the power received at the optical hub from each optical network unit and adjusting the power transmitted from one or more optical network units to reduce the overall dynamic range. For each optical network unit, the hub may determine the received optical power in an upstream signal from the optical network unit and receive a digital representation of the transmitted power. The hub may determine to adjust the optical power sent from one or more of the optical network units to reduce the dynamic range. The adjustments to the optical powers at the optical network units may be performed by sending commands from the optical hub to each adjusted optical network unit via a downstream signal.Type: GrantFiled: April 19, 2018Date of Patent: September 3, 2019Assignee: ZTE CorporationInventors: Jun Shan Wey, Junwen Zhang

Patent number: 6810175Abstract: An apparatus and method for generating a mode-scrambled optical signal. A laser beam source directs an optical signal into a free end of a first segment of multimode fiber comprising a graded-index (GI) fiber core at an offset from the centerline of the core, generating an offset-launch condition. The first segment of multimode fiber is operatively coupled into a second segment of multimode fiber comprising a step-index (SI) fiber core.
