  • Fiber optic loop support
    Patent number: 6439777
    Abstract: A testing device for fiber optic system devices includes a fiber optic loop support that holds a single-mode optical fiber such that an empirically determined loss characteristic associated therewith is unvarying from use to use. In particular, an optical fiber forms a loop, and the loop is supported within a rigid slotted housing. The housing effectively precludes bending losses. Additionally, the housing is small and portable so that field testing may also be performed.
    Type: Grant
