The first multifiber port is associated with a first fiber count and each of the plurality of fiber ports has an associated fiber count less than the first fiber count. A first of the waveguides has an associated first tap waveguide to tap a portion of an optical signal propagating along the first waveguide as a first tap signal. The first tap signal is directed to an out-of-plane reflector in the substrate that reflects the first tap signal received from the first tap waveguide out of the plane of the substrate to a detector.
G02B 6/42 - Coupling light guides with opto-electronic elements
G02B 6/28 - Optical coupling means having data bus means, i.e. plural waveguides interconnected and providing an inherently bidirectional system by mixing and splitting signals
A fiber alignment device including a plurality of fiber alignment components that are assembled with one another. At least some of the fiber alignment components include a molded alignment substrate defining fiber alignment grooves. The fiber alignment device includes elastomeric material for biasing optical fibers into the alignment grooves.
Optical fiber management trays with adjustable retention arrangements for improved installing and removing of fiber management components on the trays without the need for adhesive or fasteners. The adjustable retention arrangements can include nesting features for minimizing a profile of a stack of the trays.
Optical fiber management trays with label mounting arrangements for improved installing and removing of labels on the trays without the need for adhesive and without the need for fasteners. The arrangements can include stems with bulbous portions that receive openings defined by the label.
Fiber management organizer assemblies of telecommunications closures. The assemblies include a basket for holding portions of optical fibers and a fiber management tray support structure that pivotally supports fiber management trays. A fiber retainer can be selectively mounted at any of a plurality of mounting locations defined by the tray support structure or another structure based on specific fiber management requirements for a given organizer.
The presence of a plug connector with a port is detected through a detection circuit activated by a port shutter. Transitioning the port shutter between the closed (i.e., blocking the port) position and the open position actuates and deactuates the detection circuit.
A cable mounting tray includes a plurality of cable mounting locations for mounting cables to a management tray. The management tray is used within an enclosure. Each mounting location includes a bracket for receiving a cable and a cable clamp or tie. The cable mounting tray can snap to the management tray in a quick fit arrangement. The cable mounting tray includes two cable mounting locations on opposite sides of the cable mounting tray. A middle mounting location can be provided for mounting additional elements to the cable mounting tray, including an additional cable, such as a branch, a closure pressurization valve, or a closure grounding rod. A combined splitter and splice holder module is used on management tray. An enclosure latching arrangement is also disclosed. The latching arrangement enables the effective and reliable tool-assisted opening and closing of the latch arrangement.
Antennas are provided herein that include a parasitic element that is coupled to an active element and a ground plane. In some embodiments, the active element is inside an outline provided by a combination of the parasitic element and the ground plane. Moreover, the active element and the parasitic element are, in some embodiments, on opposite surfaces, respectively, of a printed circuit board.
A distributed radio access network (RAN) includes a new radio unit (RU) being connected to a front-haul network. The new RU determines its own Internet Protocol (IP) address based on its MAC address; and send a discovery message to all radio controllers in the front-haul network via a multicast address. The distributed RAN also includes a plurality of radio controllers communicatively coupled to the new RU via the front-haul network. Each of the plurality of radio controllers are configured to receive the discovery message and determine whether the new RU is assigned to the respective radio controller. Each of at least one radio controller, to which the new RU is assigned, establishes at least one configuration session with the new RU.
H04W 84/02 - Hierarchically pre-organised networks, e.g. paging networks, cellular networks, WLAN [Wireless Local Area Network] or WLL [Wireless Local Loop]
The present disclosure relates generally to fiber management trays that have features such as cable management structures positioned on the tray in such a way that its bend radius does not fall below a minimum bend radius of fiber. A bend radius limiter is positioned adjacent a cable entry region, where the bend radius limiter includes a raised support member elevated with respect to a base such that the bend radius limiter is offset upwardly from the base to define a cable routing pathway beneath the raised support member from the cable entry region to a fiber loop-storage region. The base can include adapters in a group that is asymmetrically positioned relative to a longitudinal axis of the tray.
Fiber management organizer assemblies of telecommunications closures. The assemblies include a base, a main body, a basket for holding portions of optical fibers and a fiber management tray support structure that pivotally supports fiber management trays. The basket mounts to the main body with a snap feature. The basket is mountable in two positions, a forward position, and an oppositely facing reverse position. The main body mounts to the base with a snap feature, including a spring loaded plunger, and a slidable engagement feature including a surrounding lip. The trays and the main body include a slidable locking feature for holding one or more trays in a rotated position away from lower structure of the organizer.
