る。Even in the case of a complete failure of the tape core wire, it is of course possible to switch the core wire by sequentially repeating the same procedure as the switching connection in the case of a failure of the core wire in the tape. However, the switching connection in units of one core is naturally inefficient compared to the switching connection in units of tape. When the detour tape route cannot be set only with the same optical cable loop 1A in the case of such a tape core wire failure, the spare tape core wire switching connection between the loops is performed using the switch connection function between arbitrary ports of the loop switching component 10. , A detour route to the station can be set via the adjacent optical cable loop 1B, and the detour route can be set by operating the switching control device 18, the n × m switching unit 19, the intra-station single-core switching component 11, the transmission line testing device 16, and the like. Confirmation test and switching connection of faulty core wire and faulty tape core wire to the bypass route can be performed.

The relocation of the obstacles to the cables is due to road construction and involves the change of the route for laying the optical cable loop. In order to carry out the trouble relocation work, the current transmission line used for the current service is temporarily switched and connected to the detour route, then the installation route is changed, and the original route is restored from the detour route. Switching connection is required. In this switching connection, it is necessary to perform switching connection within a switching time of tens of ms or less in order to shorten the line disconnection time of the active transmission device.

It is necessary to be able to transmit wavelengths from 3 μm to 1.6 μm with low loss, and the switching component also has an optical wavelength of 1.3 μm.
It is necessary that wavelengths from m to 1.6 μm can be switched and connected with low loss. Further, the switching component needs to be able to hold its switching position by self-holding without power at the time of switching connection. Therefore, it is indispensable to apply a connector type switch to the switching parts. For single-core unit switching connections, modification is made to single-core connection structure connectors such as SC connectors, and for tape-fiber unit switching connections, multi-core connection connectors such as MT connectors and other multi-core connection connectors are modified. By adding, the required switching connection function can be realized. The switching connection of the N × M matrix switch for each single core such as a single-core switching part in a station can be easily realized by moving a plurality of facing single-core connector ferrules separately in the row direction and the column direction (Japanese Patent Application No. 63-63). -326036 optical fiber switch). Also, an n × m matrix switch in units of tape cores such as an n × m switching unit can be realized in the same manner by replacing the single-core connector ferrule with a multi-core connector ferrule. These matrix switches are disclosed in Japanese Patent Application No. 3-172759 <
The optical fiber switching device> can also be used. The loop cutout part requires an arbitrary connection function for a plurality of routes of the tape core wire, and can be realized by the structure shown in Japanese Patent Application No. 3-99207 <Matrix connection of arbitrary connection> and Japanese Patent Application No. 3-99208 of <Matrix optical switch>.
