If you have NBN FTTP (Fibre to the Premises), there is a fibre optic cable that connects:
Outside NBN box (PCD) → Inside NBN modem (NTD).
This cable is usually a single-mode SC/APC fibre patch cable, which is the standard connector used for NBN fibre installations.
Many people replacing or extending their fibre cable get confused because there are multiple types available. The main difference between them is durability and protection.
Below is a simple guide to help you choose the right one.
1. Standard Fibre Cable (Most Homes Need This)
For most households, a standard fibre patch cable is all that is required.
