Patent number: 8931961Abstract: A fiber-optic connector for connecting an optical fiber to other optical assemblies is disclosed. The fiber-optic connector includes a top plate having a window of similar refractive index and transmission index as the material of an optic fiber to be contained within the fiber-optic connector. The fiber-optic connector also includes a ferrule connected to the top plate via multiple spring-loaded screws. The ferrule includes an interface and an insert. The insert is capable of firmly gripping an optical fiber. In order to reduce Fresnel reflection losses of the fiber-optic connector, the window is pre-coated with an anti-reflective surface on the side opposite an optic fiber to be contained within the fiber-optic connector.Type: GrantFiled: September 26, 2013Date of Patent: January 13, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Joseph M.

Patent number: 8894298Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.Type: GrantFiled: July 15, 2013Date of Patent: November 25, 2014Assignee: US Conec, LtdInventors: Jillcha Fekadu Wakjira, Darrell R.
