![]() The adapter body provides mechanism to hold the connector bodies such as snap-in, push-and-latch, twist-on or screwed-on. Ferrules slide into the sleeve and mate to each other. At the center of the adapter there is a cylindrical sleeve made of ceramic (zirconia) or phosphor bronze. Instead a fiber mating sleeve (adapter, or coupler) sits between two connectors. Unlike electronic connectors, most fiber optic connectors don’t have jack and plug design. Stress relief boot designs are different for 900um tight buffered fiber and 1.6mm~3mm fiber cable. Stress relief boot covers the joint between connector body and fiber cable and protects fiber cable from mechanical damage. This provides the strength for mechanical handing of the connector without putting stress on the fiber itself. ![]() Connector housing provides the mechanism for snapping into a mating sleeve (adapter) and hold the connector in place.įiber cable and strength member (aramid yarn or Kevlar) are crimped onto the connector sub-assembly body with a crimp eyelet. The end of the ferrule protrudes out of the sub-assembly body to mate with another SC connector inside a mating sleeve (also called adapter or coupler).Ĭonnector sub-assembly body is then assembled together with the connector housing. The ferrule is then assembled in the SC sub-assembly body which has mechanisms to hold the cable and fiber in place. The end of the fiber is at the end of the ferrule, where it typically is polished smooth. A 124~127um diameter high precision hole is drilled in the center of the ferrule, where stripped bare fiber is inserted through and usually bonded by epoxy or adhesive. SC connector is built around a long cylindrical 2.5mm diameter ferrule, made of ceramic (zirconia) or metal (stainless alloy). ![]() SC Connector Structure Elements in a SC connector The example shown is a SC connector which was developed by NTT (Nippon Telegraph and Telephone) of Japan. Although the mechanical design varies a lot among different connector types, the most common elements in a fiber connector can be summarized in the following picture. Now that you have a better understanding of ST Connectors, you can appreciate their importance in maintaining smooth connectivity within our digital world.More than a dozen types of fiber optic connectors have been developed by various manufacturers since 1980s. From LANs to telecommunications and data centers to broadcasting, ST Connectors ensure efficient and seamless transmission of signals. Their bayonet-style design, twist-lock mechanism, and ceramic ferrules make them an excellent choice for various applications. ST Connectors play a crucial role in the world of network and telecommunications, providing a secure and reliable connection for fiber optic cables. Broadcasting and Multimedia: ST Connectors are also employed in broadcasting and multimedia environments, enabling seamless transmission of high-quality audio and video signals.Data Centers: Data centers often utilize ST Connectors for interconnecting fiber optic cables within racks and cabinets, ensuring efficient data transmission.Telecommunications: ST Connectors are used in telecommunication networks for connecting fibers within distribution frames, patch panels, and equipment.Local Area Networks (LANs): ST Connectors are commonly used in LANs for connecting fiber optic cables to network devices such as switches, routers, and servers. ![]() ST Connectors find widespread use in various applications within the network and telecommunications industries. This ensures efficient transmission of light signals between the fibers. Physical contact connection: ST Connectors use a physical contact connection method, where the fiber ends come into direct contact with each other.The use of ceramic ensures durability and reduces the risk of damage to the fibers. Ceramic ferrules: ST Connectors feature ceramic ferrules, which are precisely engineered components that align and protect the fibers during connection.Twist-lock mechanism: The twist-lock mechanism provides added security, preventing accidental disconnections or looseness.This design ensures a secure and stable connection. Bayonet-style design: The bayonet-style design allows for quick and easy connection and disconnection of fiber optic cables.ST Connectors have several distinguishing features that set them apart from other types of fiber optic connectors: This mechanism ensures a firm and stable connection between the fibers, minimizing the risk of signal loss or interference. It features a bayonet-style design that utilizes a twist-lock mechanism to secure the connection. An ST Connector, also known as a Straight Tip Connector, is a type of fiber optic connector used to terminate and connect fiber optic cables.
