24 molten fine storage trays can be set in the said molten fine storage tray slot, hold 288 cores altogether.
Be provided with the slot of 24 blade inserting optical branching devices in the said blade inserting optical branching device slot.
Described blade inserting 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 minute optical fiber of twice beam split fiber cable cross connection box of the utility model is:
(descending) optical cable gets into the below of casing at the bottom of the case and is fastened on the outdoor optical cable installing plate; Pipe core bundle behind the optical cable baring is fastened on the optical cable baring unit installing plate; Continue through tail optical fiber and the two 12 integrated pallets of core welding distribution (up optical cable welding terminal tray), each adapter port of accomplishing optical cable welding terminal tray with jumping fiber again is connected with each input end of blade inserting optical branching device; The output terminal of blade inserting optical branching device directly connects with it through the storage tail optical fiber in the molten fine storage tray, and the time spent can directly not be stored in the pallet, the other end of tail optical fiber welding in the molten fine storage tray, and promptly branched cable is connected to the user.
When the fiber cable cross connection box of the utility model uses as the one-level optical splitting point of secondary beam split, hand over to the secondary optical splitting point from light and should to adopt two core fibres, wherein a core is as leading fibre; The first use; Another core is fine as being equipped with, and when the shunt port of secondary optical splitting point can not satisfy the demands, can increase optical branching device in the secondary optical splitting point; At this moment, second core fibre can be used as dilatation.If the second core fibre dilatation not enough, can adopt the new clothes casing, directly give out light cable to mode dilatations such as user or change splitting ratios.
The good effect of twice beam split fiber cable cross connection box of the utility model is:
(1) contains molten fine storage tray and blade inserting optical branching device, can carry out twice beam split (fibre), store up the requirement that fine capacity satisfies 288 cores;
(2) greatly reduce jumping fiber, reduced insertion loss; In casing, adopted simultaneously the optical branching device of 1 * 8,1 * 16 low splitting ratio to make twice light splitting technology be achieved; Because the use of blade inserting optical branching device does not take the groove position of molten fibre and storage tray; Therefore do not influence the design capacity of casing, satisfied the requirement of optical communication technology new fiber cable cross connection box;
(3) manufacturing cost and use cost is low, helps fiber-to-the-home promotion and application.
