ST Fiber Optic Connector is with twist-lock bayonet coupling, its 2.5mm keyed ferrule . Typical ST connector use metal housing.
Description of ST Fiber Optic Connector
ST Fiber Optic Connector stands for Straight Tip – a quick Release bayonet style Connector developed by AT&T. STs were predominant in the late 80s and early 90s.
ST Connectors are among the most commonly used Fiber optic connectors in networking applications. They are cylindrical with twist lock coupling, 2.5mm keyed ferrule. ST Connectors are used both short distance applications and long line systems. The ST connector has a bayonet mount and a long cylindrical Ferrule to hold the fiber. Because they are spring-loaded, you have to make sure they are seated properly. They are easily inserted and removed due to their design. IF you experience high Light loss, try reconnecting.
ST connectors come in two versions: ST and ST-II. These are keyed and spring-loaded. They are push-in and twist types. They are rated for 500 mating cycles. The typical Insertion Loss for matched ST connectors is 0.25 dB.
The ST connector (straight tip) is the standard connector type for installations. It is frequently used in local networks. A typical feature of the ST connector is the bayonet connection, also known as the BFOC connector (bayonet FO connector). The standard ST FO connector for telecommunications (USA), LAN, industry, medical and sensor technology. The ST FO connectors meet the standards: IEC 61754-2 and CECC 86 115-801. The ST Standard mating adapters (metal) can be used for all ST FO connectors (not just Diamond products).
ST fiber connector is with twist-lock bayonet coupling, its 2.5mm keyed ferrule meet the durability and repeatability requirement for the fiber optic links. Typical ST fiber optic connector use metal housing, but plastic housed ST connectors are also used sometimes.
ST connectors are generally three types:
single mode ST UPC fiber optic connector
single mode ST APC fiber optic connector
multimode ST UPC fiber optic connector.
ST connector is with twist-lock bayonet coupling, its 2.5mm keyed ferrule . Typical ST connector use metal housing.
ST connector adopts standard anti-rust and wear-resistant round metal body, and the bayonet is fixed, the connection is firm, and the disassembly is convenient.
High quality ferrules
Selected ceramic ferrule, professional grinding technology, precise docking of fiber end face; lower insertion loss ≤0.15dB, making transmission more stable and connection more efficient.
