摘要： A fiber transition segment for transitioning an optical fiber from a hydrophone module to the central axis of the module. The segment comprises a conical, elongated element and a cylindrical portion of reduced diameter that protrudes longitudinally from the wide end of the conical element. The cylindrical portion is reciprocally mounted within an interconnect spring at the end of the hydrophone assembly. The fiber transition segment has a helical internal groove for receiving the optical fiber from the interconnect spring. The groove is aligned with and approximately matches the pitch of the groove in the interconnect spring to provide a smooth transition to the fiber transition segment and then to the central axis of the module.

摘要： A termination assembly for use in an optical hydrophone module, comprising a module oil seal and an optical fiber seal. The termination assembly is used at the ends of modules and provides a means for filling individual modules with fill fluid. A module oil seal comprises a cylindrical wall defining a cavity, with one end substantially closed and the other end open. An annular face plate on the open end makes a seal dividing a coupling and a clevis. A check valve is mounted to an orifice that passes through the substantially closed end of the module oil seal. Optical fibers pass through the substantially closed end and the optical fiber seal is provided around the optical fiber that passes therethrough. The fiber seal fits snugly in a module oil seal opening. Both components serve to provide a seal that can withstand high pressures and maintain optical fiber integrity.

摘要： A wavelength tunable optical device comprises a polarization maintaining (PM) optical fiber having a length, a first end, a second end, and an initial birefringence. The PM optical fiber receives polarized light from a first polarizer adjacent to the first end of the PM optical fiber. A second polarizer receives a light output from the second end of the PM optical fiber. A wavelength tunable optical device provides a plurality of spectral peaks leaving the second polarizer with a periodicity determined by the length of the PM optical fiber. Each of the plurality of spectral peaks has a wavelength dependent upon the length and the initial birefringence of the PM optical fiber. The PM optical fiber is a radiation tunable optical fiber adaptable to a tuned birefringence such that the periodicity and each of the wavelengths change to a selectively tuned wavelength and a tuned periodicity.

摘要： A light-emitting module structurally suspended between a pair of spaced apart electrical conducting wires wherein each of the wires has selected portions that are electrically insulated from the module. The light emitting module, in concert with the electrical conducting wires, provides structural support for the light emitter portion of the light emitting module via the connections to the insulated and non-insulated portions of the electrical conducting wires. A plurality of light emitting modules may be ganged together in series, parallel or series-parallel electrical configurations to produce chains of light emitting modules. The chains of light emitting modules produce selected or desired illumination depending on the quantity of light emitting modules being ganged together.

摘要： A fiber management frame and an interconnection closure including the fiber management frame are provided for securely retaining optical fiber connection trays once the closure is placed into service, while also permitting access to any of the trays to reconfigure the connections of the optical fibers without disturbing the remaining trays. The fiber management frame includes a support for holding at least one such tray selected from the group consisting of a splice tray, a coupler tray, and a connector panel. The fiber management frame may also include a bias member, such as one or more tension members, for urging each tray toward the support. As such, the bias member releasably secures each tray to the support. The fiber management frame may also include at least one adjustable member, such as an upstanding bracket, that cooperates with the support to define a space for housing at least one tray.
