Abstract
The invention relates to an optical fiber branching unit tray, which comprises a bottom layer tray and a top tray, wherein the bottom layer tray is connected with the top tray through a detachable hinge; a protective cover plate is arranged on the top tray; adapter screens are arranged at the front of both the bottom layer tray and the top tray; a pigtail hole allowing a pigtail to pass through is arranged on the top tray; and lock catches are arranged corresponding positions on the bottom layer tray and the lateral surface of the top tray. When locked, the side lock catches form a whole; and when the lock catches are loosened, the top tray can turn along the axis of the hinge. Because a single layer is changed into a double layer, the splitting ratio is enlarged by one time, and the optical branching ratio is improved greatly.
Description
Technical field
The present invention relates to optical communication product, be specifically related to optical fiber branching unit tray.
Background technology
Along with the fast development of the communication technology, FTTH (Fiber to the home) will become Optical Access Network final a kind of access way and can large-scale network-estabilishing, and as FTTH core light device----optical fiber splitter will large-scale application.The optical fiber splitter that has at present two kinds of forms: a kind of is fused biconical taper formula optical fiber splitter (FBT), its volume is larger, is generally boxlike encapsulation, and another kind is planar waveguide-type optical fiber splitter (PLC), be characterized in that volume is little, density is high, be generally naked formula or boxlike encapsulation.Optical fiber branching unit tray is a kind of product for communications equipment room and access net system; conventionally be installed in fibre distribution frame, fiber cable cross connection box, optical cable fiber-dividing box; to complete the fixing and protection to optical fiber splitter, and realize the scheduling of fiber port and the protection of optical fiber splitter tail optical fiber.And current optical fiber branching unit tray can not be applied to the occasion of large splitting ratio (1: 64).
Summary of the invention
The object of the present invention is to provide a kind of optical fiber branching unit tray, to solve existing fiber branching unit tray, can not meet the technical matters of the demand of larger splitting ratio.
The present invention reaches the technical scheme that above-mentioned technical purpose adopts to be:
A kind of optical fiber branching unit tray; it is characterized in that: comprise bottom dish and take over a business; bottom dish and take over a business between for removable chain connection; describedly be provided with cover sheet on taking over a business; described bottom dish and take over a business be equipped with above adapter screens; describedly be provided with the tail optical fiber that can penetrate by tail optical fiber on taking over a business and bore a hole, described bottom dish and take over a business position corresponding on side and be provided with snap close.
Described bottom dish and take over a business between be also provided with the folded dish in one or more centres, it between the folded dish in described centre and bottom dish, is removable chain connection, the folded dish in described centre with take over a business between be removable chain connection, among the folded dish in described a plurality of centre, two adjacent centres are removable chain connection between folding and coiling, on the folded dish in described centre, being provided with the tail optical fiber that can penetrate by tail optical fiber bores a hole, the folded dish in described centre be equipped with adapter screens above, among the folded dish in described a plurality of centres, between two adjacent folded dishes in centres, on side, corresponding position is provided with snap close.
Described bottom dish, middle folded dish and take over a business on be provided with fiber winding ring.
Described adapter screens and front are the angle of 15 ~ 30 degree, and screens place can be installed FC, SC, LC, ST type adapter by cassette.
Described bottom dish, middle folded dish and the middle part of taking over a business are provided with the fixedly screens of the naked PLC optical branching device of elastic construction.
Described snap close is sliding shackle.
Described fiber winding ring is connected for dismountable cassette with bottom dish, middle folded dish with between taking over a business.
Described each screens of adapter screens can two SC adapters of clamping.
The guide rail that described bottom dish both sides setting and the guide rail bar of distributing frame match.
After having adopted technique scheme; owing to comprising bottom dish and taking over a business; bottom dish and take over a business between for removable chain connection; on taking over a business, be provided with cover sheet; described bottom dish and take over a business be equipped with above adapter screens; on taking over a business, be provided with the tail optical fiber that can penetrate by tail optical fiber and bore a hole, bottom dish is provided with snap close with the position of taking over a business correspondence on side.Side lock padlock firmly allows them become as a whole, after snap close unclamps, take over a business and can overturn along hinge axes, owing to having become bilayer by individual layer, therefore, splitting ratio has expanded one times, greatly improved light along separate routes than, in addition, folded dish in the middle of also can increasing according to the difference of the splitting ratio of optical branching device, enter one improve light along separate routes than, can be practically applicable to different splitting ratios simultaneously, splitting ratio is adjustable; Because fiber winding ring is replaceable and taking-up, adapter screens is applicable to different adapters, so energy simultaneous adaptation planar waveguide-type optical fiber splitter and fused biconical taper formula optical fiber splitter; Finally, owing to having adopted the stack of flip-shell, therefore convenient to operation.
