The present disclosure describes, among other things, a method for attaching a fiber optic terminus of a fiber optic connector to a fiber optic cable. The method may include determining a type of epoxy to be mixed from a first material in a first barrel of the dual-barrel cartridge and a second material in a second barrel of the dual-barrel cartridge. The method may include determining a first rate at which to advance a first plunger against the first barrel based at least in part on the type of epoxy to be mixed. The method may include determining a second rate at which to advance a second plunger against the second barrel based at least in part on the type of epoxy to be mixed. The first rate and the second rate may be associated with a proportion between an amount of the first material and an amount of the second material to mix for the epoxy.

Epoxy dispensing system and dispensing tip used therewith

An apparatus includes: a cleaver configured to automatically cleave a bare fiber extending from an end face of a terminus or connector of a fiber optic cable, the cleaver including a bending element configured to bend the bare fiber and a defect-formation device configured to create a surface defect in surface of the bare fiber under tension when the bare fiber is bent by the bending element; and an abrader configured to automatically finish the end face of the terminus or connector after the bare fiber is cleaved.

Devices and methods for automatically cleaving and abrading cables

The present application is directed towards systems and methods for efficient installation of optical and electrical cable in watercraft. A manufacturer may terminate one end of a cable in a location removed from the watercraft, allowing use of automated cable termination machines for efficiency and consistency of terminations. The single-terminated cable may then be brought to the watercraft and installed by pulling or routing the unterminated end through ductwork and pipes, watertight bulkhead throughways, and cable trays and ladders as necessary, prior to termination. Accordingly, more difficult and expensive on-site labor is reduced, and reliability is greatly increased. Furthermore, many cable tests that require termination but cannot be executed post-installation can be performed prior to installation, to ensure that at least the first termination, performed off-site, is error-free, reducing later troubleshooting and further increasing installation efficiency.

An apparatus is provided for shaping an end of an optical fiber. The apparatus may include a frame and a clamp constructed to hold the optical fiber in a fixed location relative to the frame. The apparatus may further include a tip shaper supported by the frame and movable in a first direction toward and away from the clamp, and moveable in a second direction that lies in a plane transverse to the first direction to shape the end of the optical fiber when the tip shaper is placed in contact with the optical fiber. The apparatus may include an abrasive substrate which abrades the end of the fiber.

Apparatus for shaping the end of an optical fiber

An apparatus and method for cleaning an optical fiber supported by a fiber optic connector. The cleaning apparatus may include a housing, a cleaning tip supported by the housing and a cleaning wipe advanceable along at least a portion of the cleaning tip to clean an optical fiber when the cleaning wipe engages the optical fiber. The apparatus may include one or more automated features which may enhance the effectiveness of the apparatus. The apparatus may include a fluid dispenser to wet at least a portion of the cleaning wipe with a cleaning fluid. The apparatus may be configured to automatically control the force exerted by the cleaning tip against the optical fiber and/or to automatically control tension in the cleaning wipe. Aspects of the invention are directed to a method of cleaning an end face of an optical fiber by advancing a wet portion of a cleaning wipe across the end face, and thereafter advancing a dry portion of the cleaning wipe across the end face. A cleaning wipe may also be provided with at least one fluid barrier to prevent fluid flow between two adjacent portions of the cleaning wipe.

Apparatus and method for cleaning an optical fiber

An automated fiber preparation system and method for automatically fabricating an optical fiber. One or more fabrication processes associated with fiber preparation may be performed on an optical fiber without requiring active user input. The fiber preparation system may be configured to automatically carry out each of the process steps for fabricating an optical fiber pigtail. The fiber preparation system may include a fiber preparation module that is configured to automatically prepare one or both ends of an optical fiber in anticipation of one or more subsequent manufacturing processes involving the fiber.

Apparatus and method for automated preparation of an optical fiber

There is provided a method and apparatus for automatically cleaning a portion of an optical fiber. One embodiment of the apparatus comprises a fluid tank assembly that holds cleaning fluid and comprises an aperture sized and arranged to receive the portion of the optical fiber, an ultrasonic generator, a clamping assembly, and a controller. The clamping assembly, in one position, holds the portion of the optical fiber in a position that is axially aligned with the aperture of the fluid tank assembly and disposed through the aperture of the fluid tank assembly. The clamping assembly further comprises a sealing assembly that forms a fluid seal about the portion of the optical fiber and a fluid seal of the aperture of the fluid tank assembly. The controller controls the ultrasonic generator to provide an ultrasonic signal to the fluid within the fluid tank assembly to clean the portion of the optical fiber.

Method and apparatus for cleaning an optical fiber

A batch thermal cycler for large numbers of biological or chemical samples uses n modules each in good thermal contact with the samples, but substantially isolated from one another, thermally and functionally. Each module carries samples on an upper sample plate. The module has a temperature sensor adjacent the samples, an electrical resistance heating element, and a circulating fluid heat exchanger for step cooling. Heating occurs at a point generally between the samples and the source of the cooling. The modules are individually replaceable. O-rings automatically seal fluid and electrical interfaces. An electrical controller has n simultaneous channels that provide closed loop control of the electrical power to each module. As a method, the invention includes at least one modular temperature zone where the temperature is sensed at a point adjacent the samples in that zone. The samples are heated adjacent the sample plate. Cooling is by a step change. The cooling overshoots a set lower temperature. A small, well-controlled heating corrects the overshoot.

High throughput thermal cycler

An actuator operates an upper plate assembly which holds a plurality of metal rods, such that all the rods are moved together along parallel longitudinal axes into respective tubes. The plurality of tubes is held by a lower plate assembly, a different tube for each rod. Liquid (sample fluid) is drawn into the individual tubes by the actuator raising the upper plate assembly with respect to the lower plate assembly and hence causing the rods to simultaneously traverse the length of the respective tubes from the distal ends of the tubes to the proximal ends of the tubes. The collected liquid is dispensed by the actuator lowering the upper plate assembly such that the metal rods are simultaneously lowered into the corresponding tubes. The rods are lowered very rapidly and stopped abruptly. This imparts sufficient velocity to the collected sample fluid within the tubes such that the samples under inertia separate from and cleanly exit the distal ends of the tubes. As such, low volume (microvolume) dispenses are enabled in a manner free of sample contact with the target (receiving) tray.
