Differences between SC connectors

Polarity: SC connectors can be configured in different polarity types, including simplex, duplex, and polarity reversal. Simplex SC connectors have one fiber, while duplex SC connectors have two fibers for bidirectional communication. Polarity reversal SC connectors are used to flip the transmit and receive fibers to ensure proper signal transmission.

End face type: SC connectors are available in different end face types, including UPC (Ultra Physical Contact) and APC (Angled Physical Contact). UPC connectors have a flat end face, while APC connectors have an angled end face. APC connectors are typically used in applications that require high performance, such as in cable television or military applications.

Connector housing: SC connectors are available in different housing types, including standard and low profile. The standard housing is the most common and provides a secure and stable connection. Low profile housing, on the other hand, is designed for high-density applications where space is limited.

Ferrule material: The ferrule is the part of the connector that holds the fiber. Ferrules are typically made of ceramic or metal. Ceramic ferrules are more common because they provide a smooth surface for the fiber to rest on, resulting in a more reliable connection.

Color coding: SC connectors are often color-coded to indicate the type of fiber and the end face type. For example, single mode SC connectors may be blue, while multimode connectors may be beige. UPC connectors may be blue, while APC connectors may be green.
