Description

The beam split distributing box

Technical field

The utility model relates to a kind of beam split distributing box that the optical communication Access Network adopts the passive optical network PON access way that is used for.

Background technology

Along with the develop rapidly of the communication technology and industry, the transmission of optical fiber has begun therefrom long Distance Transmission progressively to short-range fiber-to-the-home direction expansion.Existing Optical Access Network mode normally directly connects the point-to-point mode in each user or building with optical fiber.There is following drawback in point-to-point optical communication Access Network wire laying mode like this: 1, the optical cable consumption is big, and how many users are arranged, and just must put how many core optical cables to user side from exchange, and this has increased the transmission construction cost on the one hand, has also increased maintenance difficulties on the other hand.Very inconvenient when 2, the trunk link switches to reserve cable, can only switch one road optical fiber at every turn, not only operate loaded down with trivial detailsly, and efficient is low.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of beam split distributing box that is used for the optical communication Access Network at the deficiency of above-mentioned prior art existence, and it can simplify the optical communication Access Network, reduces the optical cable use amount and also makes the link switching more convenient.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include box body 2, install optical splitter 5 in the box body, fiber-optical socket 1 is set on the panel of box body, described fiber-optical socket comprises a primary input fiber-optical socket and a plurality of shunt accessory power outlet, the primary input fiber-optical socket joins by the primary input optical fiber interface of optical fiber 4 with optical splitter, and accessory power outlet joins by the multichannel beam split output interface of optical fiber 3 with optical splitter along separate routes.

Press such scheme, described optical splitter is provided with standby input optical fibre interface, and standby input optical fibre interface joins by the standby input optical fibre socket that is provided with on optical fiber 4 and the panel.Described fiber-optical socket 1 is oblique fiber-optical socket.

Press such scheme, described optical splitter splitting ratio is 1: 16 or 1: 32 or 1: 64 or 1: 128, and the multichannel beam split output interface of optical splitter is 16 or 32 or 64 or 128.

The beneficial effects of the utility model are: the beam split distribution function that 1, has realized the PON net in modular mode, be the interface that PON net maintainer provides unified fiber-optical socket interface conduct to administer and maintain, simplified the layout of Optical Distribution Frame (0DF) and the maintenance and management work of PON net.2, adopt the mode of EPON (PON) in Optical Access Network, by optical branching device demultiplexing light signal, the shared optical fiber of a plurality of users constitutes a kind of point-to-multipoint access network wire laying mode with the single channel light signal.So both can save the consumption of optical cable, and reduce the construction cost of transmission network, and can simplify the optical communication Access Network again, it is more convenient that link is switched.3, optical splitter is provided with a master, two-way input interface fully, primary, spare input optical fibre is connected, inject light signal only for during normal the use primary input optical fiber, when in case primary input optical fiber goes wrong, need only light signal be received on the standby input optical fibre in exchange and get final product, the reliability of Optical Access Network is further strengthened.4, on wiring mode, combine the characteristics of optical splitter splitting ratio and communication system transmits equipment distribution, the modularization of facilitating product.And on the structure can with the Wiring module compatibility of former communication system wiring closet, as the sub-frame of distribution of 72 cores in the sub-frame of beam split distribution of 32 fens optical splitter Wiring modules of 32 being formed 1 96 core and the former distributing system outside on the framework assurance consistent, thereby guarantee the interchangeability of two kinds of products, be convenient to transformation former distributing system.
