Description

FIELD OF THE INVENTION id="p-1" id="p-1" id="p-1" id="p-1" id="p-1" id="p-1" id="p-1"
[001] The present invention relates generally to optical fiber connectors. More specifically, the present invention relates to optical fibers connector having dual purpose connectable end.
BACKGROUND OF THE INVENTION id="p-2" id="p-2" id="p-2" id="p-2" id="p-2" id="p-2" id="p-2"
[002] Optical fiber connectors are small devices located at the end of an optical fiber, for enabling quicker connection and disconnection to and from external devices. The connectors mechanically couple and align the cores of fibers so light can pass. Optimal connectors will lose very little light due to reflection or misalignment of the fibers. There are about 100 different types of fiber optic connectors in the market. id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3" id="p-3"
[003] As optical fibers replace metallic fibers as the main communication line in both general and domestic applications, it became necessary to insert (e.g., thread) optical fibers inside communication conduits such as tubes inserted into walls. Threading delicate items such as optical fibers in communication conduits is challenging. In order to maintain as little loses as possible, the end of the optical fiber is polished to a very high degree (e.g., ADS 0.05 microns). If threaded into a communication conduit having any one of the known type of connectors, the end will lose it’s optical properties and will require a new polishing, on site. High degree of optical polishing in sites, such as, construction sites, is difficult to achieve and very expensive. id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4" id="p-4"
[004] Accordingly, there is a need for a simple solution that will enable threading optical fibers in communication conduits while maintaining and securing the highly polished surface at the fiber’s end.

[0013] Some aspects of the invention are directed to a connector for optical fibers having dual purpose. In some embodiments, the connector may include an end connector configured to connect the optical fiber to any known device or additional fiber. The end connector can be any end connector known in the art, such as, LC connector, FC connector, E-2000 connector, etc.). In some embodiments, the end connector may be replaced with an end pulling cap configured to be inserted and pulled inside a conduit, while maintaining and securing the highly polished surface at the fiber’s end. id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14"
[0014] Reference is now made to Fig. 1 which is an illustration of an exploded view of an optical fiber connector according to some embodiments of the invention. A connector 20 may include a hollow gripping element 12 (illustrated also in Figs. 2A and 2B), configured to grip an optical fiber 15 threaded in hollow gripping element 12, and at least one of: an end connector 9 configured to connect the optical fiber to an external device; and an end pulling cap 7 configured to be inserted and pulled inside a communication conduit.
