Scheduling ----------------- After an optical cable is introduced into the ODN device, part of the optical fiber is directly drawn out without being cut or spliced; another part of the optical fiber is spliced and drawn out with the optical fiber of another optical cable.
Divergence ----------When the optical path diverges, the optical cables are not directly connected by welding or other means, but the active connection method of wiring is used.
Straight-through ----------------- After a large-core-count optical cable enters the ODN device, it is divided into multi-channel small-core-count optical cables, and the total number of optical fiber cores remains unchanged.
