The invention relates to a cable assembly for communication purposes. The cable assembly includes a communication cable having a free, front end and a communication connector. The communication cable can be passed through a cable guide from a starting position to an end position with its free, front end. The communication cable includes at least one optical fiber that is coaxially surrounded by at least one cable sheath, within which at least one strain-relieving element is present. The communication connector can be mounted to the free end of the communication cable in communicative contact with the optical fiber.To make it possible to pass the communication cable through the cable guide, the optical fiber is exposed at the communication cable's free, front end, which is fixedly surrounded by a connecting element. The connecting element can be mechanically connected to the communication connector after the communication cable has passed through the cable guide.Thus, the communication connector can be connected in communicative contact to the optical fiber by way of a simple mechanical operation after the cable assembly has been led to the end position. Complex and costly finishing operations need not be carried out at the end user's location.
