The ST/UPC Fiber Pigtail SM 0.9mm G657A1 1.5m yellow (Part number: 1STU-X.S1-0.9SXJ1S1.5mY) from Mikrolink Fiber is a Fiber Pigtails with a ST /UPC 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.
Each type of single-mode fiber has its own area of application, and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single-mode optical fiber to the present day. Choose the right fiber is very important for each project/installation. The OS2 G.657 standard single-mode fibers were developed to allow a better bending radius regarding the G.652 standard. For the OS2 G.657 fiber there are 4 subcategories: G.657.A1, G.657.A2, G.657.B2, G.657.B3. The G.657.A1 fiber type is characterized by 10 mm minimum bending radius. These specifications of the G.657 fibers allow to have a better cost-efficiency due to compact cable designs and reduced space requirements.
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.
UPC (Ultra Phisical Contact), is a type of polishing procedure that makes a connical end face ferrule minimizing the interference of dust particules in the connectors mate. It as a Return loss >-50dB. UPC connectors may only be mated with other UPC or PC connectors. It can be identified by the blue boot and is used in single-mode and multi-mode fibers.
