Abstract
A fiber optic connector contains a housing on which either a male or a female ferrule is mounted. A cable entering from one end of the fiber optic connector is spliced into multiple optical fibers. The tips of the optical fibers are coated with diamond-like carbon (DLC) thin films which are transparent for signal transmission within a wavelength range from 820 nm to 1625 nm. Two fiber optic connectors can be connected by intermating the male and the female ferrules, in which the two corresponding optical fibers are aligned with or without physical contact.
