<P>PROBLEM TO BE SOLVED: To provide a fault recovery method in a two-core two-way communication network whereby communication between two-core two-way communication apparatuses can be recovered by way of only one optical fiber core wire. <P>SOLUTION: The recovery method includes: a step S11 of disconnecting two optical fiber core wires 71, 72 from first and second two-core two-way communication apparatuses 50, 60; a step S12 of connecting a single-core two-way communication adaptor 10 to the first two-core two-way communication apparatus 50 and connecting another single-core two-way communication adaptor 10 to the second two-core two-way communication apparatus; and a step S13 of connecting the single-core two-way communication adaptor 10 connected to the first two-core two-way communication apparatus 50, to the other single-core two-way communication adaptor 10 connected to the second two-core two-way communication apparatus 60 via one optical fiber core wire 72. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
