The invention relates to an optical fiber sensing device (9), comprising a base (1), an actuator (3) having an actuator axis (X), an elastic hinge (2) connecting the actuator to the base, allowing the actuator to move or deflect in a movement plane (D) with respect to the base, a pair of optical fiber portions (4) extending in the movement plane, contacting the actuator in a pair of contacting positions (11), wherein the actuator (3) comprises a symmetry plane (S), wherein the pair of optical fiber portions (4) are symmetrically arranged with respect to the symmetry plane, such that the movement of the actuator causes a proportional or equal change in strain in the optical fiber portions (4).

A floating quad connector assembly is designed to hold two pairs of simplex connecters in a quad formation and to permit the two pairs of connectors to float within the assembly, thereby rendering the quad connector assembly compatible with different quad adapters having different spacings between the two middle simplex ports. Also, a segmental switch module is configured to aggregate multiple category-rated connectors in an array formation while permitting the spacings between the connectors to float, thereby rendering the switch module compatible with port arrays of different port-to-port spacings.

Disclosed is an optical interconnection device that includes an alignment ferrule assembly formed from an alignment substrate and optical fibers. The optical interconnection device also has an alignment assembly formed by a planar support member with guide features. A receiving region resides between the guide features in which the alignment substrate is secured.

A light guide receptacle for mounting a plurality of light guides in the interior of a housing part, with a plurality of light bulkheads, is configured to arrange the plurality of light guides, which are mechanically coupled to one another by means of a web, in each case in intermediate spaces between two light bulkheads of the plurality of light bulkheads and to optically decouple spatially adjacent light guides from one another by means of the respective light bulkhead, wherein the plurality of light bulkheads are integrated components of the housing part.

An adapter configured to permit a heat shrink splice holder portion of a fiber splice cassette to hold a mechanical crimp splice protector includes a base portion and a holding portion configured to extend from the base portion The holding portion may be configured to hold a first splice protector, and the base portion may be configured to include a receiving feature that may be configured to couple the adapter with a fiber splice cassette. The receiving feature may be configured to couple the adapter with a splice protector holder portion of a fiber splice cassette that is unable to hold the first splice protector so as to convert the splice protector holder portion to a splice protector holder portion that may be configured to hold the first splice protector.

A optoelectronic assembly is provided including a photonic integrated circuit (PIC) including at least one electronic connection element and plurality of waveguides disposed on a PIC face, a printed circuit board (PCB) including at least one PCB electronic connection element, which is complementary to the at least one electronic connection element of the PIC and the PIC is configured to be flip chip mounted to the PCB, a lidless fiber array unit including a support substrate having a substantially flat first surface and a signal fiber array including a plurality of optical fibers supported on the first surface, and an alignment substrate disposed on the PIC face and configured to align the plurality of optical fibers of the signal fiber array with the plurality of waveguides.

The clip for securing two fiber optic connectors may include a first engagement member having a top surface and a length; a second engagement member spaced apart from the first engagement member; and a linkage member extending between the first and second engagement members and connecting the first engagement member and the second engagement member. A space is defined between the first and second engagement members to house the connectors. The linkage member is configured to separate the two fiber optic connectors when they are sandwiched between the first and second engagement members.

Optical fiber mass splice methods and assemblies are provided. A method may include securing a fiber clamp to a fiber setting fixture, the fiber setting fixture including a fiber alignment block and a backstop. A plurality of fiber grooves may be defined in the fiber alignment block. The method may further include inserting a plurality of optical fibers into the fiber setting fixture such that each of the plurality of optical fibers is disposed in one of the plurality of fiber grooves and contacts the backstop. The method may further include loading, after the inserting step, each of the plurality of optical fibers into the fiber clamp. The method may further include clamping the plurality of optical fibers in the fiber clamp.

A light-emitting device includes a board, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover having a plate shaped main cover body covering the light-emitting element and a tubular portion which receives a light guide body that guides light emitted from the light-emitting element. The main cover body includes a base, a protrusion protruding from the base toward the board, and a ridge disposed on a protruded end of the protrusion. A step is formed by the protrusion and the ridge, and the protrusion and the ridge extend in a same direction along the base.
