Description
(1) technical field
The utility model relates to a kind of fiber cable cross connection box.Be exclusively used in the EPON of Optical Access Network and the GPON system interface as backbone optical cable and optical distribution cable.Realize that Fiber to the home and optical fiber arrives buildings.Belong to the optical device technical field.
(2) background technology
Fiber cable cross connection box is the interfacing equipment of backbone optical cable and optical distribution cable in GPON (ethernet EPON of new generation) and EPON (ethernet EPON) Optical Access Network, capacity 288 cores.The distribution of the welding of realization optical fiber, the storage of optical fiber, optical fiber is passed by on one's way with optical cable and is connected.Communicating at present the construction of aspect energetically, especially Fiber to the home, and optical fiber is all realized by GPON or EPON principle to buildings.With residential quarters is example, after backbone optical cable is sent to the sub-district with the high power capacity signal, be with signal allocation to each resident family, this distributes the signal of simple optical fiber with regard to requiring, the distribution of light signal realizes that by optical branching device optical branching device just must place in the fiber cable cross connection box.Optical branching device mainly is 1:32 at present, and promptly 1 the tunnel is divided into 32 the tunnel.At present, in the fiber cable cross connection box of usefulness, the mounting means of shunt mainly is to use branching unit tray, and 33 SC adapters are installed on branching unit tray, and wherein 1 is the access that is used for signal, and 32 are used for signal output.Shunt places in the pallet, as Fig. 1.Pallet and molten join integrated single-deck and be fitted together.Some is 19 inches standard distributing frames directly placing 1U in fiber cable cross connection box, and distributing frame can only be adorned 21 adapters, can not satisfy the interface capacity of 1:32 shunt.More than in the method for two kinds of placement shunts the latter no longer be used, the main flow form is for the former.
Now just place the mode of pallet to analyze to shunt.Can load onto 33 SC adapters in order to satisfy a pallet, in fact can adorn 34,,, actually use 33 interfaces, leave a blank or standby for one so the adapter installing port occurs in pairs because be to be divided into two rows on the structure.Owing to will satisfy 33 adaptor interfaces, the height of pallet equals two molten summations of joining integrated single-deck height.Therefore a pallet has just taken two molten spaces of joining integrated single-deck.Conventional cable cross-connecting box for one 288 core capacity, its standard configuration is 24 and molten joins integrated single-deck, because a pallet has just taken two molten spaces of joining integrated single-deck, therefore, the fiber cable cross connection box of capacity 288 cores is actually does not in theory have 288 cores, can't cover 288 users.If make a fiber cable cross connection box 5 1:32 optical branching devices of the just necessary configuration of user of cover-most to greatest extent, cover 5 * 32=160 user altogether.Use 5 pallets, these 5 pallets have taken 10 molten spaces of joining integrated single-deck altogether.Join integrated single-deck because 24 of multipotency configurations of the fiber cable cross connection box of one 288 core are molten, therefore, now fiber cable cross connection box can only be joined 14 at most and moltenly be joined integrated single-deck, each is molten joins integrated single-deck 12 SC or FC interface, have 168 interfaces, wherein use the signal input of 5 interfaces as optical branching device, also remaining 163 interfaces, multipotency covers 163 users.Therefore but 5 optical branching devices can only cover 160 users, and the in fact multipotency of the fiber cable cross connection box of one 288 core covers 160 users, wherein has 3 interfaces idle.So just can't satisfy the requirement of concentrating dwelling house.
Further analyze again from Fig. 1, owing to adopted dress optical branching device in the pallet, the tail optical fiber joint of optical branching device is connected with SC adapter on the pallet, after entering fiber cable cross connection box from EPON or the descending light signal of GPON by optical cable, in nethermost molten joining in the integrated single-deck and the tail optical fiber welding, tail wires of fiber optics is connected with molten SC adapter of joining on the integrated single-deck again.Therefore, in fiber cable cross connection box, from molten joining to increase an optical patchcord between the input port of integrated single-deck signal output to the pallet and connect.5 optical branching devices just need 5 wire jumpers; Simultaneously, also want an optical patchcord to connect from the signal output on the pallet to melting between the input port of joining integrated single-deck.When full configuration, to increase by 165 optical patchcords altogether, cost has also just increased.Wire jumper one increases, and the fiber optic storage space is just not enough uses, and brings inconvenience to administering and maintaining.Moreover, analyze from signal quality, the optical power attenuation of light signal mainly is because line length and splicing loss produce in the cable link, each splicing loss is 0.5dB, in the conventional cable cross-connecting box, connect with an optical patchcord to melting between the input port of joining integrated single-deck from the signal output on the pallet, therefore increased an active joint, corresponding circuit has also increased the optical power loss of 0.5dB.Optical power loss and transmission range are the relations of being inversely proportional to, and power attenuation is big, and transmission range is just short.
