Description
Technical field
The present invention relates to optical-fibre communications equipment technical field, specifically, is a kind of twice light splitting optical cable transfer box using in Fiber to the home (FTTH).
Background technology
Optical fiber technology is very general in the application of China, and Fiber to the home (FTTH) is the development of current optical fiber communication technology and the raising of user's request and the new measure that adopts, and it need to use many optical fiber dispensing apparatus and parts.Realize after Fiber to the home, family's broadband access ability can exceed 100 megabits per second, and the effect of its application is very obvious.
Outdoor optical cable is switched in the each household resident family of residential quarters and will and continues through a series of fiber distribution, at present, in city or population concentration occupy residence and adopt fiber cable cross connection box to realize more.Traditional fiber cable cross connection box just continues and completes distribution and the storage to optical fiber backbone optical cable and branched cable or user's optical distribution cable.Along with popularization and the utilization of PON technology, fiber cable cross connection box is improved to guide tracked fusion integrated tray can settle tray type optical branching device, has given the intension of " light splitting " that fiber cable cross connection box is new.In fiber cable cross connection box, be connected with user's optical fiber of a great deal of (1～32,64) with a fibre core, realize the distribution of light path.
Along with the raising of optical communication technology level, the lifting of key equipment performance index is achieved the technology utilization of " twice light splitting ", and in the urgent need to the fiber cable cross connection box that can realize twice light splitting is provided.But existing fiber cable cross connection box can not be realized the function of twice light splitting, meanwhile, although adopt the problem that has solved a light splitting after tray type optical branching device,, make actual light hand over the corresponding minimizing of capacity owing to having taken the space of integrated pallet.Therefore, existing fiber cable cross connection box structurally can not meet the requirement that optical communication technology is new.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of twice light splitting optical cable transfer box is provided, contain molten fine storage tray and insert type optical branching device, can carry out twice light splitting (fibre), fiber storage capacity can meet the requirement of optical communication technology to new fiber cable cross connection box, and manufacturing cost and use cost is low, be conducive to fiber-to-the-home applying.
For addressing the above problem, the technical scheme that the present invention takes is:
A kind of twice light splitting optical cable transfer box, contain casing, the chamber door hinged with casing, between chamber door and casing, be provided with buckle lock structure, below casing, be provided with optical cable installing plate and fiber cable cross connection box stationary installation, optical cable baring cellular installation plate is set above optical cable installing plate and fiber cable cross connection box stationary installation, it is characterized in that, in casing, the right side of the first half is provided with entablature, sill, left crossbeam and right crossbeam, described left crossbeam and right crossbeam form inserting slot construction, the top of described inserting slot construction is up optical cable welding district, its interpolation connects row optical cable welding terminal tray, the bottom of described inserting slot construction is molten fine storage tray slot, can insert molten fine storage tray in it, in casing, the left side of the first half is provided with left rail and right guide rail, and described left rail and right guide rail form the insert type optical branching device slot that can insert insert type optical branching device.
Described up optical cable welding district is provided with the slot of two up optical cable welding terminal trays, and every up optical cable welding terminal tray has 12 cores.
24 molten fine storage trays can be set in described molten fine storage tray slot, hold altogether 288 cores.
In described insert type optical branching device slot, be provided with the slot of 24 insert type optical branching devices.
Described insert type optical branching device is 1 × 8 optical branching device (can also adopt 1 × 16 optical branching device, corresponding take two groove positions).
The process of twice point of optical fiber of twice light splitting optical cable transfer box of the present invention is:
(descending) optical cable enters the below of casing and is fastened on outdoor optical cable installing plate at the bottom of case, pipe core bundle after optical cable baring is fastened on optical cable baring cellular installation plate, continue by tail optical fiber and two 12 core welding distribution integrated pallets (up optical cable welding terminal tray), then complete being connected of each adapter port of optical cable welding terminal tray and each input end of insert type optical branching device with jumping fiber; The output terminal of insert type optical branching device directly connects with it by the storage tail optical fiber in molten fine storage tray, and the used time can directly not be stored in pallet, the other end of tail optical fiber welding in molten fine storage tray, and branched cable is connected to user.
In the time that fiber cable cross connection box of the present invention uses as the one-level optical splitting point of secondary light-splitting, hand over to secondary light-splitting point and should adopt two core fibres from light, wherein a core is as main fibre, first use, another core, as standby fine, in the time that the shunt port of secondary light-splitting point can not satisfy the demands, can increase optical branching device at secondary light-splitting point, now, the second core fibre can be used as dilatation.If the second core fibre dilatation not enough, can adopt new clothes casing, directly give out light cable to user or change the mode dilatations such as splitting ratio.
The good effect of twice light splitting optical cable transfer box of the present invention is:
(1) contain molten fine storage tray and insert type optical branching device, can carry out twice light splitting (fibre), fiber storage capacity meets the requirement of 288 cores;
(2) greatly reduce jumping fiber, reduced insertion loss; In casing, adopt the optical branching device of 1 × 8,1 × 16 low splitting ratio that twice light splitting technology is achieved simultaneously, because the use of insert type optical branching device does not take the groove position of melting fine and storage tray, therefore do not affect the design capacity of casing, met the requirement of optical communication technology to new fiber cable cross connection box;
(3) manufacturing cost and use cost is low, is conducive to fiber-to-the-home promotion and application.
