Connectors Connectors make temporary connections among equipment that may need to be rearranged. Offset of fiber cores by 10% of their diameter can cause a 0.6 db loss. Losses arise when cores are elleptical or off center. ngular misalignment of fiber ends can causes LT/CTS-04A/1009 6 of 28 Angular misalignment of fiber ends can causes significant losses. Different NA can contribute to connection losses. Misaligned fiber axes cause losses.
