International Classification:

G02B 600

US Classification:

385 59

Abstract:

An improved assembly for housing actively aligned VCSELs or detectors to a light transport terminal, such as a ferrule, and a method and technique for actively aligning VCSELs and laser detectors to a light transport terminal, such as a ferrule, are provided. The method actively aligns an array of VCSELs or laser detectors to a light transport terminal, such as a first ferrule. The aligned components can then be secured to a retainer housing which can receive a plug. Then a plug, having a second ferrule with V-groove alignment portions and a substantially rectangular housing encasing the second ferrule, can be inserted into the retainer housing, thereby passively aligning the array of optical fibers carried by the second ferrule of the plug to the array of optical fibers of the first ferrule by way of posts extending from the first ferrule into the V-grooves of the second ferrule. A VCSEL or detector to optical fiber plug assembly is thus provided.

Berg Technology, Inc. - Reno NV

International Classification:

G02B 636

US Classification:

385 83

Abstract:

An optical connector comprising a ferrule, optical conductors, and epoxy. The ferrule has an optical conductor receiving area and guide pin receiving areas. The ferrule comprises at least two ferrule members having shaped surfaces on outer lateral sides which form the guide pin receiving areas. The ferrule members comprise mating projections and recesses proximate the outer lateral sides and between the optical conductor receiving area and the guide pin receiving areas which form epoxy seals. The optical conductors having portions located in the optical conductor receiving area. The epoxy is located in the optical conductor receiving area to connect the portions of the optical conductors to -the ferrule. The epoxy seals prevent the epoxy from flowing into the guide pin receiving areas.

International Classification:

G02B 636

US Classification:

385 78, 385147

Abstract:

An optical fiber connector subassembly comprising a first housing member and a first optical fiber locator. The first optical fiber locator is connected to the housing member. The locator is comprised of silicon and has channels for positioning optical fibers therein. The housing member comprises a recess. At least a portion of the locator is located in the recess to interlock the locator with the housing member.

Assignee:

Berg Technology, Inc. - Reno NV

International Classification:

G02B 642

US Classification:

385 88, 385 60

Abstract:

An optical connector assembly comprising a base, an optical fiber connector, and a spring. The base is adapted to be fixedly attached to a printed circuit board. The optical fiber connector has an outer housing movably mounted to the base. The spring biases the optical fiber connector in a predetermined direction relative to the base.

F16L 33/00

US Classification:

24279

Abstract:

A T-bolt pipe clamp of the quick-attach type in which a head portion of the T-bolt can be inserted into or removed from one of the connecting ends of the clamp. The clamp has first and second loop ends that are drawn together during tightening by a T-bolt fastener. The first loop end has a latch insert that accepts the head portion of the T-bolt and provides additional strength to the loop end. The latch insert can include a tab to help guide the T-bolt into the loop end and thereafter prevent it from too easily disengaging the loop end.

Inventors:

Drew Demangone - Latrobe PA, US

International Classification:

G02B006/36

US Classification:

385/078000

Abstract:

An optical connector ferrule comprising a main section comprising optical fiber receiving areas, and side sections on opposite lateral sides of the main section. The optical fiber receiving areas comprise a single slot which is sized and shaped to receive a plurality of spaced optical fibers and is adapted to keep the optical fibers spaced from each other in the slot.
