A connector assembly includes a flexible cable that includes a casing, a plurality of electrical wires each having a first portion encapsulated by the casing and a second portion extending beyond the casing, and a fiber having a first portion encapsulated by the casing and a second portion extending beyond the casing. The connector assembly further includes a housing having a first end to receive the flexible cable and a second end with a connector to connect with another connector, and a circuit board disposed in the housing. The circuit board includes first terminals to connect with the plurality of electrical wires, second terminals to connect with the connector, a plurality of traces coupling respective first terminals with respective second terminals, and a cleat. The second portion of the fiber extends beyond the casing to the cleat and winds around the cleat.
