Here, the emergency fusion splice module is used to replace the fusion splice module at both ends of the faulty optical cable when the fault occurs.
Fig. 6 is a schematic diagram of a network topology-based emergency rescue method according to an embodiment of the present invention, and as shown in fig. 6, a fusion module a in an optical cable cross-connecting cabinet a and a fusion module B in an optical cable cross-connecting cabinet B are connected by an optical cable. The cables are shown as solid double-headed arrows. When the optical cable between the fusion module A and the fusion module B breaks down, for example, the optical cable is interrupted, then the optical cable is replaced by the emergency optical cable to rush to pass through, and the emergency optical cable at the position comprises two emergency fusion modules, namely an emergency fusion module A 'and an emergency fusion module B', and the emergency fusion module A 'and the emergency fusion module B' are connected through the optical cable. The emergency fusion splicing module A 'is used for replacing the fusion splicing module A in the optical cable cross-connecting box A, and the emergency fusion splicing module B' is used for replacing the fusion splicing module B in the optical cable cross-connecting box B, so that the optical cable connection between the optical cable cross-connecting box A and the optical cable B is realized, and the business borne by the original fault optical cable is cleared.
The method provided by the embodiment of the invention carries out service emergency clearing on the fault optical cable between the two optical cable cross connecting boxes in a replacement mode, and has the functions of quickly recovering damaged optical cables and carrying out emergency clearing on optical cable interruption. The fusion module is installed in the optical cable cross-connecting box through the installation guide rail, so that the fiber fusion time can be reduced, and important services can be quickly and reliably cleared.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
