The ST/PC 12 Fibers Color-coded Pigtail SM G652D 900µm 2m (Part number: 101000500400008) from Opterna is a Fiber Pigtails with a ST /PC connector. Fiber optic pigtail is a type of cable that is made of a connector at one end, and loose wires on the other. The pigtail connector side is used to link the equipment, while the pigtail side made of loose wires that are melted in order to be connected to the fiber cable. Pigtails can be single-mode or multi-mode, which can be accompanied by terminations like SC, FC, ST, LC, MU, MT-RJ, and others. It is normally used within the wall or rack mounted patch panel.
OM2 (Optical Multimode 2) is a type of multimode fiber defined by the G.651.1 standard. It has a core diameter of 50 microns and is designed for higher-bandwidth applications than OM1, supporting up to 10 Gbps over distances of up to 90 meters. OM2 is commonly used for data center applications and LANs, but is being replaced by higher-grade fibers for longer-range transmissions.
The ST FO Connector is a type of fiber optic connector that uses a 2.5mm ceramic ferrule to align and connect optical fibers. Used in high-speed data communication networks. Provides low insertion loss and high return loss. It features a bayonet-style twist lock and is commonly used in single-mode or mult-imode fiber optic applications. The connector is highly reliable and durable. It is almost obsolette, is not used in new aplications.
PC (Physical Contact), is a type of polishing procedure that makes flat surfacein the ferrule end face. The optical return loss of PC connectors is >-40dB. PC connectors may only be mated with other PC or UPC connectors. It can be identified by the blue boot and is used in single-mode and multi-mode fibers. This polishing procedure is outdated and is replaced by UPC.
