An IO connector that includes an optical communication component, for example an optical transceiver, mounted to a ferrule body of the IO connector. An uncoated fibrous mat is affixed to at least one of the faces. The instrument further includes an inner component disposed within an inner lumen of the outer component and configured to translate longitudinally relative to the outer component such that the inner component can apply a distal force to a compression member of the polyaxial screw disposed within a distal portion of the receiving member to thereby convert the polyaxial screw to a monoaxial screw. The central actuator is located inside the RV, and controlling input to the central actuator may be from a remote transmitter, or by direct manipulation of the central actuator. 5 eV or less in an atmosphere including oxygen. The coated article is heat treated sufficiently to cause the Zn-doped zirconium based layer to transform into a Zn-doped zirconium oxide based layer that is scratch resistant andor chemically durable.
