Problems solved by technology

However, when the cable consists of optical fibers, each tap made on the optical fiber leading to an ancillary item of equipment causes attenuation of the signal
Furthermore, forming taps on fiber optic cables is proving technically difficult at present

Embodiment Construction

[0038] A local computer communication infrastructure operating under a protocol such as Ethernet, ATM or "token ring" that allows data to be transmitted over optical fibers includes at the head end a main hub 1, e.g. An input connector 10 for an input, specifically an optical input, and an output connector 11 for transmitting optical signals, for example in parallel, on several optical fibers of the transmission line. The output connector 11 is an MPO (Multi-fiber Push-on), MF or MTP (trademark) type multi-fiber connector suitable for transmission line MPO (Multi-fibres Push-on), MF or MTP (trademark) connection system. MTP, MF and MPO connectors are well known and are not described in this patent application.

[0039] According to the invention, an optical fiber transmission line consists of several identical fiber segments 2a, 2b, 2c, 2d ( Hereinafter, it is referred to as 2) constitution. For example, the fiber used is of the OM2 type.

Abstract

The segment has a multi-fiber connector (22a) with four connection zones (3a, 3b, 3c, 3d), and another multi-fiber connector (22b) with connection zones (30a, 30b, 30c, 30d). Each optical fiber of a group of derived optical fibers (21a), is interrupted to form a derivation point (23) of the segment. The zone (3a) is connected to the group, and the zone (30a) is connected to another group of continuous optical fibers (21d). The zone (3d) is connected to a third group of continuous optical fibers (21b) and the zone (30d) is connected to the group (21a).

Description

technical field [0001] The present application relates to tappable cable segments comprising groups of optical fibers for use in communication infrastructure. The invention also relates to a communication infrastructure comprising at least one cable segment. This infrastructure may consist of several segments connected end-to-end. Background technique [0002] Computer communication infrastructures operating under eg Ethernet, ATM or Token Ring type protocols can assume several different topologies. The most widely known are star, bus or ring topologies. [0003] In a star topology, servers are linked to a main hub extending via several star branches to several secondary items of equipment, to which computer terminals are connected, eg directly or via network switches. Typically, in a localized infrastructure, the main hub is installed in the central area of ​​the building and the secondary equipment items are remotely located in areas as close as possible to the end user...
