Abstract:
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.

Abstract:
Indexing terminals enable rapid deployment of a distributed optical network. Each indexing terminal has a single-fiber port and a multi-fiber port. Distribution cables each have a first optical fiber that is optically coupled to the single-fiber port and other optical fibers that are optically coupled to the multi-fiber port of a respective one of the indexing terminals. Each indexing terminal shifts the fibers of the respective distribution cable over one indexed position between the two ends of the distribution cable. A connectorized end of the distribution cable is configured to be plugged into the multi-fiber port of another indexing terminal to enable daisy- chaining of the indexing terminals. Multi-service terminals may be plugged into the single-fiber ports of the indexing terminals to provide additional splitting of optical signals before providing the optical signals to subscribers.
Abstract:
A fiber optic telecommunications device includes a fiber optic cassette comprising a body defining a front and an opposite rear and an enclosed interior. A fiber optic signal entry location is defined on the body for a fiber optic signal to enter the interior via a fiber optic cable. An adapter block defines a plurality of fiber optic adapters and is removably mounted to the body with a snap-fit interlock, each adapter including a front outer end, a rear inner end, and internal structures allowing mating of optical connectors mounted to the front and rear ends, respectively. A removable spacer is mounted to the body, the spacer configured to expand the size of the enclosed interior of the cassette and a removable cover is mounted to the spacer. Connectorized optical fibers extend from the fiber optic signal entry location to the rear inner ends of at least some of the fiber optic adapters for relaying the fiber optic signal to fiber optic connectors to be coupled to the front outer ends of the adapters.

Abstract:
An optical system architecture includes indexed optical lines that are indexed between first and second multi-fiber connectors; a first of the optical line having a first end terminated at the first multi-fiber connector; and a second optical line having a first end terminated at the second multi-fiber. An input of an optical splitter is optically coupled to second ends of the first and second optical lines. The optical splitter splits optical signals carried over the first and second optical lines onto output lines so that each output line carries signals split from the first optical line and signals split from the second optical line.
