Publication number: 20170269313Abstract: A coaxial transmitter optical subassembly (TOSA) including a ball lens may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. The coaxial TOSA includes a laser package with a ball lens holder section defining a lens holder cavity that receives the ball lens. The lens holder cavity is dimensioned such that the ball lens is positioned in substantial alignment with the laser diode for optically coupling a laser output from the laser diode into an optical waveguide at an optical coupling end of the TOSA. The coaxial TOSA is thus configured to allow the less expensive ball lens to be used in a relatively small package when a lower coupling efficiency and power is desired and without substantial redesign of the TOSA.Type: ApplicationFiled: March 17, 2016Publication date: September 21, 2017Inventors: Jianhong LUO, Che-Shou YEH, I-Lung HO, Peng NIE

Publication number: 20170269319Abstract: A novel panel-mountable fiber optic cable feedthrough is described that has two main body parts that can be brought together around single or multiple fiber optic cables and secured in place to prevent slippage of the cable(s). Use of two such main body parts that split along a plane that passes through the axis of the fiber optic cable(s) allows joining the two main parts at any position along the cable(s) without the need to thread the cable(s) through a one or more pre-formed cylindrical cavities in the body of the feedthrough. The main parts for this fiber optic feedthrough can be made by plastic injection molding suitably shaped to relieve bending strain in the glass optical fiber(s) within the cable(s). The foot-print for mounting such a feedthrough can be made compatible with that of a number of popular fiber optic connector mounts, including the SC-connector.Type: ApplicationFiled: April 29, 2017Publication date: September 21, 2017Inventor: Gary Evan Miller
