Patent number: 7234875Abstract: The device includes first and second ferrules, first and second housings, and first and second holders. The first and second ferrules have respective first and second mating ends. The first housing has a first cantilever spring, a second cantilever spring, and a first recess for accommodating the first ferrule. The second housing has a third cantilever spring, a fourth cantilever spring, and a second recess for accommodating the second ferrule. The first holder is interposed between the first ferrule and the first and second cantilever springs. The second holder is interposed between the second ferrule and the third and fourth cantilever springs. In a connected state, the first mating end of the first ferrule contacts the second mating end of the second ferrule so that the first ferrule is in optical communication with the second ferrule.Type: GrantFiled: November 2, 2005Date of Patent: June 26, 2007Assignee: Stratos International, Inc.Inventors: Mark Krowiak, Joe Sutton, Mark Waldron

Patent number: 7165728Abstract: The device includes a connector, a transponder, an optical test unit, an antenna, and a transceiver. The transponder is attached to the connector. The antenna is attached to the optical test unit. The transceiver is electrically connected to the antenna. When the connector is attached to the optical test unit and the optical test unit performs diagnostic testing on the connector and its associated optical fiber, the results or data of the diagnostic testing are stored in the optical test unit for later downloading from the optical test unit to the transponder. The test data can include attenuation loss, insertion loss, and back reflection test data. Once the connector is connected to a host device, the data associated with the specific connector can uploaded from the transponder to the host device.Type: GrantFiled: December 15, 2004Date of Patent: January 23, 2007Assignee: Stratos International, Inc.Inventors: Richard C. E. Durrant, Mark Krowiak

Patent number: 6767136Abstract: A device includes two optical fibers bonded to a body. The body has a mating end and a splicing end. Each of two optical fibers has a respective polished end and splicing end. The polished end of two optical fibers is situated adjacent to and flush with the mating end of the body. The length of the two optical fibers is the same, where the length is defined by the distance from the splicing end to the polished end. The length of the two optical fibers is greater than the length of the body as defined by the distance from the mating end to the splicing end of the body. The length of the two optical fibers is less than fifty millimeters. The two optical fibers are parallel to one another.Type: GrantFiled: September 19, 2003Date of Patent: July 27, 2004Assignee: Stratos International, Inc.Inventors: Richard C. E. Durrant, Mark Krowiak
