A connector assembly includes a housing having housing cavities extending between a mating end and a loading end. The housing having module latches associated with corresponding housing cavities. Contact modules are received in corresponding housing cavities. Each contact module having first and second module cavities extending between a front end and a rear end of the contact modules. The contact modules being held within the housing cavity by the corresponding module latch. Each contact module having an unshielded twisted pair (UTP) circuit, the UTP circuit includes first and second signal wires and first and second terminals terminated to the first and second signal wires. The signal wires being twisted along a length of the first and second signal wires.
