Super miniature TFF and TFP active modular optoelectronic components are based on an optical interface that is three times less than the size of SFF/SFP components and about six times smaller than an SC based component and thus provides a density that is three times higher than LC interfaces. The invention provides substantially smaller photonic devices that can be used with substantially smaller optoelectronic components and combines the new optoelectronic components with the new smaller miniature interconnect systems such as the Push-Release type using the same interface. The new interface can be used with sub-millimeter or larger diameter ferrules. Photonic devices are mounted in a close proximity of the active end of a fiber stub thereby avoiding the need for lenses and active alignment and enabling use in active hermetic or non-hermetic subassemblies.

High density active modular optoelectronic device for use with push-release mechanism and method for using same

An optical fiber interconnect system wherein the adapter employs a push-push interconnect mechanism wherein the adapter employs a spring loaded slider that moves in a single plane in response to a first pushing force to engage the connector with the adapter and a second pushing force to disengage the connector from the adapter so that the connector can be withdrawn from the adapter. The adapter includes an automatic shutter that is opened upon contact by the inserted connector housing with a cam on the lower portion of the shutter, but avoids contact with the ferrule polished end face. Angled latches are provided on the modular contact so as to enable disengagement and removal of the contact from the remainder of the connector assembly from the front thereof.

An optical fiber interconnect system wherein the adapter is connected to and released from the holder and the connector is connected to and released from adapter through two push-release connection and release mechanisms. The connector is engaged with the adapter by applying an insertion force to the connector. The connector is released by applying a releasing force to the connection mechanism on the adapter. The system of the invention includes a holder for attachment of the adapter to a front panel. A release opening is provided on the holder for the release of the adapter from the holder from the front of the panel so as to provide access to the back connector.

An optical liquid measuring system for measuring the amount of flammable liquid in a storage tank consisting of a pair of encoder disks that are operatively connected to a pair of floats through a pair of pulley systems. The floats are designed so that the first float will float on top of flammable liquid such as gasoline, and the second float will float on top of water. Optical encoder reader heads or optical connectors are located proximate to the respective encoder disks to receive light that is reflected by or transmitted through the encoder disks. The optical connectors include a plurality of optical fibers that receive the light from the encoder disks and transmits signals to a CPU. The CPU then takes the information derived from the received signals and uses an algorithm to accurately calculate the amount of gasoline and water in the storage tank.

An alignment system is provided between a pair of connectors mateable in a given mating direction. A first connector includes a housing having an alignment projection on one side thereof. A second connector includes a housing having an alignment flange projecting forwardly thereof generally in said mating direction. The alignment flange is flared outwardly for engaging the housing of the first connector during mating and allowing a degree of misalignment between the connectors in an &ldquo;X&rdquo; direction generally perpendicular to the mating direction. The alignment flange includes a slot for receiving the alignment projection of the first connector. The slot has a flared mouth allowing a degree of misaligned between the connectors in a &ldquo;Y&rdquo; direction generally perpendicular to the mating direction and generally perpendicular to the &ldquo;X&rdquo; direction.

A method is disclosed for fabricating a connector ferrule for a fiber optic cable which includes at least one optical fiber. A pair of ferrule clamping members are provided and define a fiber passage therebetween for receiving the optical fiber and which define at least one pin passage therebetween of a given diameter. A ferrule body is formed about the clamping members. A spreader pin of a larger diameter than the given diameter is inserted into the pin passage to spread the clamping members and open the fiber passage. The optical fiber is inserted into the opened fiber passage, and the spreader pin is removed to allow the clamping members to close onto the optical fiber.

An alignment system is disclosed in a connector ferrule for a fiber optic cable which includes at least one optical fiber. A ferrule body receives the cable and includes a fiber passage for receiving the optical fiber. A pin passage in the ferrule body is spaced from the fiber passage for receiving an alignment pin projecting from the ferrule body to align the body with an appropriate complementary connecting device. An alignment bushing is disposed in the pin passage for directly receiving the alignment pin. The outside dimensions of the bushing are smaller than the inside dimensions of the pin passage to define a space therebetween. A filler adhesive is applied in the space between the outside of the alignment bushing and the inside of the pin passage. Therefore, the bushing can be precisely aligned in the pin passage from exteriorly of the passage, and the filler adhesive can fix the bushing in that precise alignment interiorly of the passage.

A method is disclosed for fabricating a connector ferrule for a fiber optic ribbon cable which includes a plurality of generally parallel optical fibers in a line. A ferrule body is provided with a fiber passage which is elongated in cross-section to receive the line of optical fibers. A jacket is removed from an end portion of the fiber optic ribbon cable to expose the line of optical fibers. The ferrule body is placed in a fixture. The cable is placed in the ferrule body with the exposed line of optical fibers located in the fiber passage, and with distal ends of the exposed fibers projecting outwardly of the ferrule body. The exposed distal ends of the fibers are located on the fixture to precisely align the fibers relative to each other in the fiber passage. A filler adhesive is applied in the fiber passage about the exposed fibers to fix the fibers in the fiber passage while the fibers are held by the fixture in their precise alignment.
