Description

  The present invention relates to an optical splitter housing mounting mechanism in which an optical splitter housing is mounted on the side of various devices such as a VDSL device.

  In recent years, digital devices such as personal computers have been widely used, and are widely used both for business use and in general households. Accordingly, in order to use digital devices provided in each room in an office or home more conveniently, a network is constructed by interconnecting these digital devices. Information transmitted and received between interconnected digital devices is large-capacity audio, images, etc., and optical fiber cables such as silica-based optical fibers and plastic optical fibers are used as transmission media for high-speed transmission of these in large quantities. Yes.

  For example, when using a VDSL device in an apartment house or building, the optical fiber cable is vulnerable to bending and difficult to route, so the optical fiber cable is routed to the common part of the apartment house or complex building, and beyond that Using a line termination unit ONU (Optical Network Unit) and a collective line termination unit / VDSL aggregation unit (hereinafter referred to as a VDSL unit), each room is connected by a telephone line such as a metal cable to form a communication network. The method is widely used.

  An ONU is a device for connecting a terminal device such as a personal computer to a network in an optical fiber subscriber communication network, and converts an optical signal flowing through the optical fiber into an electrical signal or an electrical signal sent to the optical fiber. To change the signal to light. In the case of an apartment house, a complex building, etc., the VDSL device is housed in a cabinet together with the optical line termination device ONU, and is arranged in a common part of the apartment house, the complex building, or the like. As an example of such a VDSL apparatus, one described in Patent Document 1 has been proposed.

By the way, there is a conventional VDSL apparatus as shown in FIG. The VDSL apparatus 1 is fixed to a wall surface of a building such as an apartment house or a building with a bolt or the like, and an optical cable 2 provided from the outside is connected to the VDSL apparatus 1. For example, an MDF box 4 or the like is provided as a power supply unit in addition to the VDSL apparatus 1.
Various kinds of information such as voice and images to be transmitted are distributed by the VDSL apparatus 1 and transmitted to a digital device in each room indoors while maintaining a communication speed over a telephone line such as a broadband line.
By the way, in the case where an optical splitter housing 3 having an optical wiring method different from the VDSL method used in the VDSL device 1 is installed in addition to the wall-mounted VDSL device 1 shown in FIG. An optical splitter could not be disposed inside the casing of the VDSL device 1. Therefore, it is necessary to provide an optical splitter housing 3 at a position adjacent to the VDSL device 1 and connect it with the optical cable 2, and to arrange an optical cable in each door.
