An indexing system includes an indexing component; a redundant optical path; and a fiber tap arrangement. Multiple indexing components can be daisy-chained together in the indexing system. The redundant optical path is created between any forward port and any rearward port in the network. Multiple redundant optical paths can be created within the network. One or more tap arrangements can be disposed along each redundant optical path. Accordingly, feed signals in a bidirectional indexing environment can be supplied to each drop line along the redundant optical path from either direction without recabling.

Optical tapping in an indexing architecture

An optical line terminal that includes an activation mechanism.

OLT power management system

An optical network unit may include a light sensitive unit suitable for receiving NRZ and/or PAM signals effectively. The optical network unit may include a laser transmission unit for providing NRZ and/or PAM signals effectively.

Multi-rate and multi-modulation ont and olt

Distributed optical tapping architectures include two or more optical tap terminals daisy-chained together. Each optical tap terminal includes an environmentally sealed enclosure; an optical tapping circuit positioned within an interior of the enclosure, the optical tapping circuit including an tap input, a tap pass-through output, and a tap drop output; and hardened interface locations (e.g., de-mateable fiber optic connection locations, cable-pass through glands, etc.) corresponding to the tap input, the tap pass-through output and the tap drop output.

Distributed tap architecture incorporating hardened connectivity

The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, spare ports can be providing in a forward direction and reverse direction ports can also be provided.

Fiber indexing systems

The present disclosure relates to turn-to-secure connection interface for securing two components together. The turn-to-secure interface includes stop arrangements including a snap-fit feature.

Mechanical connection interface

Holders for wound cables. The holders include retention features to control the rate at which cable windings are unwound during cable deployment. In some examples, the cable holder includes a pair of spaced apart spools and the cable is wound in windings configured as figure-8's. In some examples, the retention features include flexibly resilient fingers positioned to contact the windings at one or more retention points positioned at a deployment end of the holder.

Wound cable holder with improved cable deployment control

A passive optical network includes a central office providing subscriber signals; a fiber distribution hub including an optical power splitter and a termination field; and a drop terminal. Distribution fibers have first ends coupled to output ports of a drop terminal and second ends coupled to the termination field. A remote unit of a DAS is retrofitted to the network by routing a second feeder cable from a base station to the hub and coupling one the distribution fibers to the second feeder cable. The remote unit is plugged into the corresponding drop terminal port, for example, with a cable arrangement having a sealed wave division multiplexer.

Wave division multiplexer arrangement for small cell networks

The present disclosure relates to a fiber optic network including a plurality of fiber distribution components daisy chained together to form a chain of fiber distribution components, the chain of fiber distribution components having a first set of optical fiber paths that are indexed along a length of the chain and a second set of optical fiber paths that are not indexed along a length of the chain.

Fiber optic network architecture with parallel indexed and non-indexed fiber paths

Systems and methods for delivering multiple passive optical network services are disclosed. One system includes a first optical transmission service comprising a common wavelength pair routed from a source to each of a plurality of subscribers and a second optical transmission service comprising a plurality of unique wavelength pairs, each of the unique wavelength pairs assigned to a subscriber among the plurality of subscribers. The system includes a splitter optically connected to first fiber carrying the first optical transmission service, the splitter including a plurality of outputs each delivering the first optical transmission service, and a wavelength division multiplexer connected to a second fiber, the wavelength division multiplexer separating each of the unique wavelength pairs of the second optical transmission service onto separate optical fibers. The system further includes a plurality of second wavelength division multiplexers optically connected to a different output of the plurality of outputs of the splitter and to a different one of the unique wavelength pairs from the wavelength division multiplexer, thereby combining a unique wavelength pair and a common wavelength pair onto a single fiber to be delivered to a subscriber.

Passive optical network distribution systems and components thereof

A passive optical network includes a central office providing subscriber signals; a drop terminal; and a wave division multiplexer. A fiber distribution hub may split or separate out dedicated optical signals from subscriber optical signals between the central office and the drop terminal. The wave division multiplexer separates dedicated optical signals pertaining to a specific dedicated subscriber from other optical signals on the line received at the wave division multiplexer. The wave division multiplexer may be part of a cable or part of an intermediate service terminal.

Cable arrangement with wavelength division multiplexer

A wall box includes an enclosure having a base and a cover connected to the base. The base and the cover enclose an interior region. The wall box further includes a plurality of fiber optic adapters mounted to the enclosure. The fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure. A tray stack is mounted within the interior region. The tray stack includes a tray mount pivotally connected to the enclosure. The tray mount includes a top surface and an oppositely disposed bottom surface. A first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface. A plurality of trays is disposed in the first splice tray mounting area. A tray is disposed in the second splice tray mounting area.
