This is XCH-PC01SS-AU SC/APC to SC/UPC Single-Mode Fiber Optic Patch Cord, specifically designed for high-performance optical communication networks. It combines two distinct connector types—SC/APC (green) and SC/UPC (blue)—to provide low-loss and reliable optical signal transmission over single-mode fiber (9/125μm).

Applications
FTTH (Fiber-to-the-Home): Provides connectivity between Optical Line Terminals (OLT) and Optical Network Units (ONU) in residential fiber networks.
Telecommunications: Ideal for connecting equipment in long-haul or metro optical networks.
Data Centers: Used for high-density patching and interconnection between servers, switches, and storage systems.
CATV Systems: Facilitates the transmission of optical signals for broadband and cable television networks.
Enterprise and Campus Networks: Supports point-to-point and point-to-multipoint optical links within buildings and campuses.
