The FC/PC (Physical Contact) and FC/APC (Angled Physical Contact) connectors are standardized under TIA EIA/TIA-604-4 and IEC 61754-13.

For APC Connectors, understanding the difference between step and conical ferrules is crucial for proper polishing.

FC/APC Connectors come with different key widths tailored to specific loss requirements.
