UPC vs. APC Connectors. Which one?
APC (Angled Physical Contact) Connectors
- Endface: Features an 8-degree angled polish.
- Color: Green
- Performance: Provides lower back reflection (high return loss), as the angled surface sends reflected light into the cladding.
- Best For: High-precision applications like long-distance fiber runs, high-speed networks, and systems that are sensitive to signal reflection
- Incompatibility: Incompatible with UPC connectors
UPC (Ultra Physical Contact) Connectors
- Endface: Slight curved or domed polished surface.
- Color: Blue or Black
- Performance: Offers good performance, though with higher back reflection compared to APC.
- Best For: General purpose applications such as short to medium distance connections (i.e. LANs).
- Incompatibility: Incompatible with APC connectors
