摘要:
A connector module (1) permits termination of cross-connect wires (15) on one a front surface (4) and cable wires (21) on an opposite surface. The module exhibits a configuration, which permits test access and protector mounting from the front surface. The jumper wires (7) are inserted from a side surface through wire guides (22) or channels that bring the wires from the side surface to the front surface where the wires can be terminated without impeding insertion and removal of protection modules (8) from the front of the connector module. There is an intermediate surface below the front surface that is accessible from the front and recessed to allow protection modules to be installed completely below the terminated wires, allowing termination and maintenance of jumper wires after the protection module is installed from the front.

An apparatus for assisting a telephone service subscriber in connecting telephone equipment to a network services terminating point and in testing telephone service to the terminating point. A network services terminating point conductor insertion and test circuit tool allows a subscriber to insert a conductor to a proper depth in a network services terminating point module without damaging the module. The telephone service provider's line can be tested to the point of the network services terminating point by inserting the test circuit into the module.

Fused fiberoptic couplers of the type formed by the processes of providing the fibers, assembling them in a close-packed relationship, and heating and drawing the assembly of fibers in the close-packed region. The fiberoptic couplers (37) are fabricated from optical fibers that have optical cores (38, 46, 48, 50) and surrounding cladding and/or spacer fibers that have no core (40, 42, 44). The number of optical and spacer fibers and their relative arrangements are selected to achieve desired properties of the coupler (37). Its has been discovered that the steps involved in forming such a coupler, introduce slight size variation that can seriously affect the performance of the coupler, and that these slight variations can be accommodated by slight, controlled, under-sizing of one or more of the surrounding fibers or over-sizing of the central fiber. Other fiberoptic couplers, which may or may not be formed in the above manner, are described.

Un ensemble bloc connecteur, servant à connecter des câbles à espacement étroit transportant des signaux d'une fréquence élevée, contient des paires de doigts connecteurs élastiques, des éléments de blindage électroconducteurs étant placés entre différentes paires. Des contacts de terre sont agencés de façon qu'un module d'insertion s'y engage avant d'entrer en contact avec les doigts à ressort, et un agencement de goujon d'arrêt et d'élément en saillie sert à maintenir le module en différentes positions de fonctionnement.

摘要:
An improved fiber optic connector of the type in which a fiber supporting ferrule (15) is slidably and resiliently biased independently of the surrounding load-bearing parts of the connector so that forces applied to the fiber optic cable jacket are not transmitted to the ferrule (15) and supported fiber to interrupt communications then in progress. In one of the embodiments, the needle of a syringe is inserted into a positioning tube (16) which confines an adhesive to the needed area, and prevents wicking of the adhesive to surrounding areas where it might interfere with the sliding action of the ferrule (15). It also wipes the needle as the syringe is withdrawn. A rear body element (13) provided with internal threads (50) which surround the cable jacket, which during a crimping operation, causes the jacket to deform into the threads for superior cable retention. Alternate embodiments include a rear body having means for engaging a sheath of a fiber optic cable, key means, and crimping operations with collet-like fingers.

Un module (10) de protection d'un circuit d'abonné utilise un circuit intégré (16) pour protéger le téléphone contre des surtensions momentanées et comprend des ensembles de bobines thermiques (17) de protection contre des surintensités de courant. La protection à sécurité intégrée (13) est également prévue et devient effective en cas de défaillance de la protection à bobine thermique.
