- the terminated cable subunit is connected to the branch cable.
- the prefabricated distribution cable is made by covering the optical cable subunit in the distribution cable, and the number of optical fibers of the covered optical cable subunit is equal to the number of optical fibers that need to be diverged each time.
- the corresponding optical cable subunit can be directly separated, and the other optical cable subunits remain straight, so that the different optical cable subunits and the straight optical cable subunits are independent of each other in the distribution optical cable, thereby avoiding prefabrication in the factory.
