Abstract: A polarity checking apparatus for multi-fiber connectors includes a body, a diverging lens attached to the body and a screen attached to the body, wherein the apparatus is configured to determine test and/or determine polarity of the multi-fiber connector. The screen may be translucent or may be opaque in part and rotatable for checking whether a signal is being transmitted on an individual optical fiber position of the multi-fiber connector. The invention is also directed to a method for checking the polarity of an optical assembly.

Abstract: According to certain aspects of the present invention, an optical cable assembly is disclosed having a plurality of optical fibers, each having a first end and a second end. The plurality of optical fibers includes a first group of optical fibers and a second group of optical fibers. A first connector head is attached to the first end of the first group of optical fibers. The first group of optical fibers terminates in an array at a surface disposed on the first connector head. The first connector head includes a first mating structure. A second connector head is attached to the first end of the second group of optical fibers. The second group of optical fibers terminates in an array at a surface disposed on the second connector head.
