Abstract

A connector includes a housing (12, 12', 12', 222), a channel extending through the housing (12, 12', 12', 222) and at least one collet assembly (14, 14', 156, 156', 267) mounted in the housing (12, 12', 12', 222). The at least one collet assembly (14, 14', 156, 156', 267) includes a collet (78, 78', 78', 184, 268) configured to move from a closed position in which an optical fiber (F, F') is held in the connector to an open position in which the optical fiber (F, F') is removable from the connector. The collet assembly (14, 14', 156, 156', 267) further includes a bias element (42, 42', 194, 290) configured to bias the collet (78, 78', 78', 184, 268) to the closed position. A method includes the steps of applying a pressure to a collet assembly (14, 14', 156, 156', 267) against a biasing force of a bias element (42, 42', 194, 290) to slidably move a collet (78, 78', 78', 184, 268) of the collet assembly (14, 14', 156, 156', 267) from a closed position to an open position, inserting an optical fiber cable (F, F') into the collet assembly (14, 14', 156, 156', 267) and releasing the pressure on the collet assembly (14, 14', 156, 156', 267) such that the collet (78, 78', 78', 184, 268) moves to the closed position under the force of the bias element (42, 42', 194, 290) to hold the optical fiber (F, F') cable in a connector.
