Q

The shape and angle of the tip of a fiber-optic connector can have an impact on the performance of a fiber-optic communication link. The two basic types of fiber end are Ultra Physical Contact (UPC) and Angled Physical Contact (APC). In the UPC-type connector, the connector end is polished with no angle, while APC connectors feature a fiber end polished at an 8-degree angle. Besides additional labeling (UPC or APC) that helps in identifying further details about a given connector type, fiber-optic connectors can also have different colors. The rule of thumb is that a UPC-type connector typically would be blue while APC connector would have a green color.

Category 7 is a twisted-pair cabling standard featuring improved specifications for canceling crosstalk and system noise. As in Cat 6A, Cat 7 cabling offers 10 Gbps data transfer rate over a cable segment length of 100 meters in 10GBaseT networks. Category 7 standard introduces new connector types (the GG45 and TERA connector).
