Description
A fiber optic patch cord is a connection consisting of a fiber optic cable and connectors that allows to connect two fiber optic devices. It is one of the most important elements of a fiber optic network, as it allows the transmission of an optical signal between devices.
Types
Fiber optic patch cords are available in different lengths, with different types of connectors, such as:
– SC (Subscriber Connector) is a type of optical fiber connector. It features a push-pull latching mechanism and a 2.5 mm ferrule. Considered to be one of the most popular connector types due to its high performance and relatively low cost.
– LC (Lucent Connector) is a small form factor fiber optic connector. It uses a 1.25mm ferrule and is known for its high-performance and reliability.
– MPO (Multi-fiber Push On) is a type of fiber optic connector that is designed to support high-density fiber optic applications. MPO connectors use a multi-fiber ferrule that can hold up to 72 fibers in a single connector. This allows for a large number of fibers to be connected in a small area, making it ideal for use in data centers and other high-density fiber optic networks.
– E2000 is a type of fiber optic connector that has automatic closing after removal from the adapter. This feature protects the connector against dirt. It uses a 2.5mm ferrule.
– ST (Straight Tip) connector is a type of fiber optic connector that uses a bayonet-style locking mechanism to make connections. The ST connector uses a 2.5mm ferrule.
– FC (Fiber Channel) connector is a type of fiber optic connector that uses a screw-type locking mechanism to make connections. The FC connector uses a 2.5mm ferrule and is designed for use with both single-mode and multimode fibers. This connector is often used in high-power and high-vibration environments, such as in some industrial and military applications. It’s also commonly used in laboratory settings and the test equipment.
Some types of connectors are available with PC (Physical Contact) and APC (Angled Physical Contact) versions.
– PC connector has a straight ferrule that is parallel to the fiber’s axis.
– APC connector has a ferrule that is angled at 8 degrees. This allows for a lower return loss and more efficient coupling of light into the fiber.
