The following description of the use of synchronous methods to create fiber optics, which is wrong?
A . The fiber exists on the network management side and the network element side, and the fiber with the same information is not required to be created.
B . If there is a fiber that is not created on the U2000 or a fiber that is not created on the network element, you need to synchronize or create it.
