摘要： Optical fiber (12)extending from an optical coupler (11) is routed on a substrate layer (13) by first inserting the optical coupler in a device holder (16) having a slotted member (17). An opening in a substrate layer is made to match a cavity (19) in a support member (20). The device holder is inserted in the cavity (19) of the support member (20) and the substrate layer (13) is supported by the support member (20) such that the opening exposes the device holder (16). The optical fiber extending from the optical coupler is inserted into a slot of the slotted member (17) such that a bridging portion (21) of the fiber bridges a distance between the upper surface of the substrate layer (13) and the slotted member (17). The bridging portion of the optical fiber is engaged with a routing device, and the fiber is then muted on the upper surface of the substrate layer (13).

摘要： Detecting and evaluating optical subcircuits created by optical splitters in an optical circuit. One or more optical wavelengths are utilized for the transmission of data; whereas, other optical wavelengths are utilized to perform optical time domain reflectometry measurements on each optical subcircuit. Following an optical splitter, each optical path from the optical splitter has inserted into it an optical filter which allows the transmission of the optical wavelengths utilized for data transmission and one of the optical wavelengths utilized to perform the optical time domain reflectometry measurements. An optical time domain reflectometry instrument transmits each of the optical wavelengths, utilized for testing, individually into the optical circuit and analyzes the returned optical pulse. Since only one optical subcircuit allows the passage of any given optical wavelength for testing, each optical subcircuit can be fully analyzed.

摘要： An apparatus to determine characteristics of an optical communication path by utilizing electrical devices in an electrical path in parallel with the optical communication path. Each electrical device is physically located with a passive or active optical device and specifies the attenuation and delay of the optical device. A receiver measures the electrical qualities of each electrical device in the electrical path which is parallel to the optical path from the optical transmitter. The electrical measurements allow the receiver to automatically adjust its optical receiver to the attenuation and delay introduced by the optical devices in the optical path.

摘要： Visual indication of an operational condition on a printed circuit board by utilizing a pair of LEDs for each operational indication and by utilizing each LED of a pair to verify that the other LED can emit light greater than a predefined level. In addition, if an error condition is determined to exist in a pair of LEDs, a central processor is notified of this fact to allow the error condition to be remedied. Further, if a failure is detected in the pair, both LEDs are utilized to indicate an operational condition on the printed circuit board. This increases the probability that the LED pair will be able to indicate the operational condition.

摘要： An optical switching unit requiring no optical-to-electrical conversions on optical data paths being switched through the optical switching unit. The optical switching unit receives optical data information from one terminal and switches it to another terminal. The optical switching unit frame synchronizes the data transmission timing of the terminals in accordance with the data transmission timing of the optical switching unit. This frame synchronization eliminates the need to provide data buffering and frame synchronization in the optical switching unit. The optical switching unit comprises an optical network, system clock, optical input interfaces for receiving information from terminals, and optical output interfaces for transmitting information to terminals. The system clock determines the timing of each terminal using information transmitted to an optical input interface by the terminal. If the timing of a terminal does not match that of the system clock, the system clock blocks the transfer of data information by the optical input interface to the optical network and transmits timing information to the terminal via an optical output interface. If the timing matches, the system clock signals the optical input interface to communicate the data information to the optical network which switches the data information to optical output interfaces for transmission to terminals.

摘要： An optical coupler using round optical fibers whose ends have been formed into a predefined shape to allow greater physical packing densities in order to achieve greater uniform illumination efficiency. The interstitial space between optical fibers is greatly reduced by thermoforming the ends of round optical fibers in a mold that makes a gradual transition from a circular shape to the predefined shape to avoid optical loss. Since the change in shape is gradual, the total cross-sectional area of the fibers remains constant; and optical loss is minimal becuase there is no reduction in mode volume. The predefined shape may be substantially square or rectangular. The core and cladding materials of the optical fiber are carefully chosen with respect to the glass transition state temperatures of both materials because the temperature at which the materials are formed by a mold are slightly above the glass transition state of the core or cladding, whichever is higher.

摘要： A cladding portion (15) of an optical fiber (16) is laser machined by focusing a laser beam (13) that is of an appropriate wavelength to ablate the cladding. When the laser beam completely penetrates through the cladding (15) to impinge on the optical fiber core (18) light is transmitted to the two ends of the fiber. A photodetector (31) is placed in close proximity to one of the ends of the optical fiber (16) with the photodetector output being connected to a laser control device (23). When the light detected by the detector exceeds a threshold, it generates a signal that stops the laser. Even if the cladding is of an unpredicted thickness, the laser beam is not terminated until there has been complete penetration through the cladding, and after complete ablation the laser beam is promptly terminated so as to avoid subsequent damage to the optical fiber.

摘要： A relatively inexpensive and relatively efficient coupler is obtained by connecting two fiber collections with a polymer material, provided the numerical aperture of the two collections are relatively well-matched to each other and to the polymer region. This efficiency is achieved despite relatively large mismatches in the refractive index of the resin material relative to the fibers. Couplers for optical backplanes are produced in one embodiment utilizing plastic materials. In this technique, a collection of fibers is inserted on each end of an enclosure such as a tube that is filled with a polymer that is subsequently cured.

摘要： A non-invasive optical fiber coupler for coupling light into an optical fiber bus through the cladding surrounding the optical fiber bus without bending the optical fiber bus. The coupler comprises a tap optical fiber free end adjacent to and facing a region of straight optical fiber bus with the tap fiber free end and optical fiber bus region encapsulated with a junction media having substantially the same index of refraction as the cladding of the optical fiber bus. Since the bus cladding is not removed nor is the optical fiber bus bent, there is no additional light lost due to the coupler from the optical fiber bus.
