Optical Connector Types - Viavi T-BERD/MTS 2000 User Manual

Optical connector types

There are many optical connectors in the market place. Always ensure to use a high
quality connector that meets the international standards.
Two main types of connectors are deployed in the telecommunication industry:
1 Straight polished connectors, so called PC or UPC
2 Angled polished connectors, so called APC
The PC or UPC-type test port is identified by a grey cap with the addition of a "PC" label.
The APC-type test port is identified by a green cap with the addition of a "APC" label.
