Fiber Optic Adapters

Fiber optic adapters connect two fiber optic connectors or cables, and are categorized by the connector types at each end (e.g., LC-LC, SC-SC), by the type of fiber (single-mode or multimode), and by their polish type (APC, UPC, or PC). Common adapter types include LC, SC, ST, and MPO/MTP, each suited for different applications, with LC and MPO adapters being more common in modern networks and data centers, respectively.

SC - SC Adapters

SC (Subscriber Connector) adapter types vary by fiber configuration, such as simplex (single fiber) and duplex (two fibers), and by polish type, including SC/UPC (Ultra Physical Contact) and SC/APC (Angled Physical Contact). They are also categorized by their mode (single-mode or multimode), typically identified by a yellow or green jacket for single-mode and an orange or aqua jacket for multimode.

Simplex SC Adapters: These support a single optical fiber.
Duplex SC Adapters: These are designed to accommodate two fibers, often used for simultaneous transmit and receive functions.
Single-Mode SC Adapters: Used with yellow-jacketed single-mode cables, these are for long-distance, high-bandwidth applications.
