Probe assembly includes a modular device configured to detect external signals or emit energy. The modular device has a device array that includes at least one of electrical contacts or optical fiber ends. The probe assembly also includes a cable assembly that is configured to communicatively couple the modular device to a computing system and transmit data signals therethrough. The cable assembly includes an array connector having a connector body that includes a mating side and channels extending through the mating side and the connector body. The cable assembly includes a plurality of communication lines that are disposed within corresponding channels of the connector body. The communication lines have respective end faces that are positioned proximate to the mating side to form a terminal array. The terminal array is aligned with and coupled to the device array of the modular device.
