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 the 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 final a kind of access way of Optical Access Network and understand large-scale network-estabilishing, and will large-scale application as core light the device----optical fiber splitter of FTTH.The optical fiber splitter that two kinds of forms are arranged at present: a kind of is fused biconical taper formula optical fiber splitter (FBT), its volume is bigger, is generally the 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 the encapsulation of naked formula or boxlike.Optical fiber branching unit tray is a kind of product that is used for communications equipment room and access net system; usually be installed in fibre distribution frame, fiber cable cross connection box, the optical cable fiber-dividing box; finishing, and realize the scheduling of fiber port and the protection of optical fiber splitter tail optical fiber to the fixing of optical fiber splitter and protection.And present optical fiber branching unit tray can not be applied to the occasion of big 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 the technical matters that the existing fiber branching unit tray can not satisfy the demand of bigger 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 the bottom dish and take over a business; the bottom dish and take over a business between connect for removable hinge; describedly take over a business to be provided with cover sheet; described bottom dish and the front of taking over a business are equipped with the adapter screens; describedly take over a business to be provided with the tail optical fiber perforation that can penetrate by tail optical fiber, described bottom dish and take over a business position corresponding on the side and be provided with snap close.
Described bottom dish and take over a business between also be provided with the folded dish in one or more centres, be that removable hinge is connected between the folded dish in described centre and the bottom dish, between folding dish and take over a business, described centre is connected for removable hinge, be that removable hinge connects between two adjacent centres are folded and coiled among the folded dish in described a plurality of centre, the folded dish in described centre is provided with and can bores a hole by the tail optical fiber that tail optical fiber penetrates, the front of the folded dish in described centre is equipped with the adapter screens, among the folded dish in described a plurality of centres between the two adjacent folded dishes in centres on the side corresponding position be 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 the positive angle that is 15～30 degree, 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 a sliding shackle.
Described fiber winding ring is connected for dismountable cassette with bottom dish, middle folded dish with between taking over a business.
But two SC adapters of each screens clamping of described adapter screens.
The guide rail that the guide rail bar of setting of described bottom dish both sides and distributing frame is complementary.
After having adopted technique scheme; owing to comprise the bottom dish and take over a business; the bottom dish and take over a business between connect for removable hinge; take over a business to be provided with cover sheet; described bottom dish and the front of taking over a business are equipped with the adapter screens; take over a business to be provided with and can bore a hole by the tail optical fiber that tail optical fiber penetrates, the bottom dish is provided with snap close with the position of taking over a business correspondence on the side.The side snap close pins and allows them become as a whole, after snap close unclamps, take over a business and to overturn along hinge axes, owing to become bilayer by individual layer, therefore, splitting ratio has enlarged one times, improved greatly 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, advance one one improve light along separate routes than, can be useful for different splitting ratios simultaneously, promptly splitting ratio is adjustable; Because fiber winding ring is replaceable and taking-up, the 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; At last, owing to adopted the stack of flip-shell, therefore convenient to operation.
