Description

The present invention relates to devices that are used in the construction of a communication network in residential multi-storey buildings, and is intended to connect and distribute internal fiber-optic communication cables to the provider's common network.

The design of the device consists of a quick-detachable base, closed with a lid and having fastening elements, where an optical splitter is installed with a division ratio of 1: 4 or 1: 8, terminated on both sides using optical fiber with optical connectors, adapters that serve to connect consumers in case of a subscriber growth base, and adapter or pigtail for optical signal input.

Comparable in technical solutions to the above description are the solutions of Raisecom and Yueqing SSSI Technology Co., Ltd and other companies producing similar products.

The solutions of Raisecom and Yueqing SSSI Technology Co., Ltd http://russian.opticalpatchcord.com/buy-splitter.plc.html are identical, because they produce optical splitters both terminated and non-terminated. These are passive optical devices in integral metal or plastic cases, having 3 or more optical outputs, dividing one input signal between two more output ones, terminated with optical connectors of different lengths with optical connectors or not terminated.

The disadvantages of the above structures is that all installation work, installation of additional adapters, an optical splitter, laying out of optical fiber stocks, control of bending radii, fixing of optical fiber at all stages of network construction, are carried out directly at the installation site, in the interfloor space, which requires the presence on-site installation of personnel with high professional skills, but even this does not guarantee the appropriate quality of work done. In addition, in most cases, when the number of subscribers changes, it is necessary to change the optical splitter with all the ensuing consequences.

The technical result of the proposed development is that a quick-detachable splitter module, which can be performed on four or eight ports, depending on the installed optical splitter and the number of adapters for connecting subscribers, the optical signal can be input through an additional adapter or a pigtail terminated by an optical connector. A factory-terminated, reusable splitter module allows you to gradually increase the subscriber base during the construction of the network without involving staff with high professional skills and at the same time ensuring the necessary quality of work.

The technical result is obtained by quick, due to the elements

fastenings in the base, factory-terminated splitter module, which can be made in four or eight ports, depending on the optical splitter used, terminated with optical connectors, and the number of adapters installed. The splitter module refers to reusable devices that have small dimensions. When building a subscriber network, the splitter module for four ports without involving qualified personnel, can be replaced with a splitter module for eight ports in the shortest possible time, with high quality of work performed.

The technical result is achieved by the design of the splitter module, which includes an optical splitter, characterized in that the optical splitter is installed in the base, closed by a lid and having fastening elements, in which subscriber connection adapters, an adapter or an optical signal input pigtail are mounted.

The positive effect of the proposed development is that the use of the splitter module when building the network, i.e. installing a splitter module on four ports, replacing it with a splitter module on eight ports, significantly reduces installation time, reduces labor costs, eliminates the use of highly qualified specialists with experience in optical fiber, while ensuring high quality of work, allows you to reuse one and the other module splitter.

An example implementation:

The splitter module of FIG. 1-4 consists of a base 1, a cover 2, an optical splitter 3 (Fig. 1, Fig. 2) or an optical splitter 11 (Fig. 3, Fig. 4), dividing the input optical signal into several outputs, in particular four or eight optical connectors 4, transmitting the optical signal through adapters 6 to the addresses of subscribers, adapter 7 and optical connector 5 (Fig. 1. Fig. 3), which are used to input the optical signal through a patch cord or via pigtail 9 (Fig. 2, Fig. .4), which is introduced into the base 2 through the input of the splitter module 10 and the optical signal is fed to the split er optic. For quick removal and installation of the splitter module at the place of operation, a fastening element 8 is used, combined with the base 1.

The principle of operation of the splitter module

The splitter module can be installed in a distribution box in case of an increase in the number of subscribers. The optical signal gets to the input of the optical splitter 3 or 11 through the adapter 7 or pigtail 9. Having passed through the optical splitter 3 or 11, the optical signal is divided into four or eight streams. Then, through the optical connectors 4 and adapters 6, the optical signal reaches the subscriber.

The advantage of the invention is that during the construction of the network there is no need for deep training of personnel in the details of working with optical fiber, the use of highly qualified specialists in the installation of equipment, while ensuring the high quality of the work performed, significantly reducing installation time, reducing labor costs, and allowing multiple use of interchangeable components, in particular a splitter module, for four ports and, if necessary, an eight-port splitter module RH.

Claims (1)

A splitter module, including an optical splitter, characterized in that the optical splitter itself is installed in the base, which is closed by a cover, in which subscriber connection adapters are mounted, an optical signal input pigtail adapter and which has a latch for quick installation and removal of the product at the place of use.
