  • Buffer layer promotion of decrease of one or more strain gradients in optical fiber winding
    Patent number: 6898364
    Abstract: An apparatus in one example comprises a buffer layer located on a face that serves as a primary support for an optical fiber winding along a first general direction. The face is coupled with a body that serves as a primary support for the optical fiber winding along a second general direction. The optical fiber winding comprises an optical fiber wound about the body. The buffer layer serves to promote a decrease of one or more strain gradients among a plurality of portions of the optical fiber winding.
    Type: Grant

  • Bifilar fog coil winding pattern with improved shupe bias canceling properties
    Patent number: 6215933
    Abstract: A bifilar FOG coil winding method employs two identical parallel fibers, each one-half the length of the final FOG coil wound between first and second payout spools so that the respective midpoint of each fiber is located between the two spools. Both parallel fibers are then wound to form a FOG coil using Frigo's quadrupole or dipole winding technique. Prior to winding, one of the payout spools is rotated 180° (degrees) about its fiber pair.
