Introduction of Opticla Fiber Patch Cord

1. What is an optical fiber patch cord?

Fiber optic patch cord refers to the fiber optic cable with connector mounted in both ends, used to achieve optical path connection. The fiber is generally cylindrical and consists of three parts: core, cladding and coating.

According to the diameter of the fiber core, the fiber is divided into single-mode fiber and multi-mode fiber. The core diameter of the multi-mode fiber is between 50 and 62.5μm, and the core diameter of the single-mode fiber is between 8 and 10μm.


2. Types of optical fiber connectors

Fiber optic connector, for physical connection, mainly includes FC, ST, SC, LC. FC is a circular spiral port, ST is a circular 45-degree bayonet plug, SC is a square socket, LC is a small core connector.

3. Types of ferrules

 Front surface structure of ceramic ferrule inside the fiber optic connectors includes PC, APC and UPC. PC has a spherical structure, APC has an 8-degree oblique structure, and UPC has a planar structure


4. Types of multimode fiber

Multimode fibers are classified into OM1, OM2, OM3 and OM4 according to the transmission rate and the corresponding light source type. The traditional OM1 and OM2 multimode optical fibers are based on LED (Light Emitting Diode) in both standard and design, while OM3 and OM4 are optimized on the basis of OM2 to be suitable for LD (Laser Diode) transmission at the same time. Compared with OM1 and OM2, OM3 has a higher transmission rate and bandwidth, so it is called optimized multimode fiber or ten-megabit multimode fiber. OM4 is further optimized on the basis of OM3, with a better transmission rate and bandwidth.
