Fiber network for interrogating fiber-optic sensors in a first Passive Optical Network (PON) and in a second PON, the fiber network comprising a test signal transceiver for emitting query signals and for receiving response signals, a first PON and a second PON. Each PON comprises a light source for generating telecommunication signals and a fiber-optic sensor. Each PON can transmit the telecommunication signals to a plurality of subscribers, and is optically connected to the test signal transceiver such that the query signals can be fed into the respective PON and propagate in the PON to the fiber-optic sensor, and such that the test signal transceiver can receive response signals from the fiber-optic sensor through the PON. The fiber network further comprises a query signal splitter, optically connected to the test signal transceiver and to the PONs such that it can feed a query signal into the PONs simultaneously, and such that it can feed response signals from the PONs into the test signal transceiver.

Fibre network comprising sensors

A termination strip () for a telecommunications module comprising at least one pair of contact elements () arranged side-by-side, each terminating in contacts () on opposed longitudinal sides () of the strip for connection to a wire pair of a telecommunications cable. Each contact element comprises: (i) two end regions () that terminate in contacts on respective longitudinal sides of the termination strip and are substantially aligned with one another along the longitudinal axis of the contact element, and (ii) a narrower central region () between the end regions, located substantially on one side of the longitudinal axis. One of the end regions comprises a resilient contact region () extending from the end region substantially on the other side of the longitudinal axis and engageable by an external component inserted into the termination strip from one of the opposed longitudinal sides. The contact elements are substantially identical but turned through 180&#xb0; relative to one another with the narrower central regions adjacent one another.

Connection and switching contact elements for a termination strip for a telecommunications module

A telecommunications terminal module () includes the following features. The terminal module () includes at least one location () for mounting a section () of a telecommunications rack (), the mounting location () is provided with surfaces () facing said section (), and the surfaces () of said mounting location () are configured such that said terminal module () can be tilted from the condition as secured to said rack () relative to said section () about one rim () thereof.

Telecommunications terminal module and combination including a terminal module

A telecommunications module includes a housing, a plurality of contacts, which are exposed to allow the connection of wires herewith, and a connecting device for connecting at least some of the contacts with other contacts of the telecommunications module, wherein the connecting device is partially accommodated in the housing an d partially extends outside the housing.

Telecommunications module

A telecommunications terminal module () is provided, having a splitter group or other electrical or electronic component () integrated in the terminal module (), and two rows of contacts (') with contacts (&#x2032;,) to which cable cores () can be connected from the outside of the terminal module (), the contacts () being connected with contacts () of the splitter group () inside the terminal module (), and the contacts () being designed in such a way that they approach each other inside the terminal module (), at least in parts, but are electrically separated from one another and are separately connected to the splitter group ().

Telecommunications terminal module

A grounding plate ( ) includes the following features: said grounding plate ( ) includes in its rear portion at least one contact section ( ) integrally formed with said grounding plate ( ) for contacting a telecommunications rack-mount ( ), said grounding plate ( ) is configured essentially flat, including said contact section ( ) and with the exception of comparatively short angled items ( ), if any, which serve for positioning said grounding plate ( ) in or on a telecommunications module ( ) relative to a direction perpendicular to the sheet-metal plane of said grounding plate ( ), said grounding plate ( ) includes in its front portion several contact fingers ( ), said grounding plate ( ) can be mounted on a telecommunications module such that each contact finger ( ) is in contact with a section of a contact of the module, and said grounding plate ( ) can be mounted together with the module on a telecommunications rack-mount such that said contact section ( ) is in contact with a mainly troughed telecommunications rack-mount, said telecommunications module is provided with one such grounding plate ( ) and said telecommunications rack-mounting system is provided with at least one such module.
