Fiber optic patch cords, as important connection components in fiber optic communication systems, are used to achieve fast connections between optical fibers and are an indispensable component in network environments such as data centers, local area networks, and metropolitan area networks. According to different classification standards, fiber optic patch cords can be divided into many types. The following are several common classification methods:

1. Classification by fiber type

Single-mode fiber patch cord: uses single-mode fiber, usually used for long-distance transmission, has lower transmission loss and dispersion, and is suitable for high-speed data transmission.

Multi-mode fiber patch cord: uses multi-mode fiber, suitable for short-distance transmission, such as internal connection in data centers, with higher bandwidth and cost advantages.

2. Classification by connector type

LC connector jumper: LC (Lucent Connector) is the most commonly used connector type in data centers. It is small and high-density, suitable for high-density wiring environments.

SC connector jumper: SC (Subscriber Connector) is an early standard connector with large size and simple operation. It is suitable for low-density wiring environments.

FC connector jumper: FC (Ferrule Connector) connector has high precision and reliability, suitable for occasions with high requirements for connection stability.

ST connector jumper: ST (Straight Tip) connector is a bayonet connector with simple operation, suitable for environments with high requirements for ease of operation.

MPO connector jumper: MPO (Multi-fiber Push On) connector is a multi-fiber connector used for connecting multiple core optical fibers, suitable for high-density wiring and high-bandwidth transmission.

3. Classification by the number of optical fiber cores

Single-core patch cord: suitable for point-to-point optical fiber connection.

Multi-core patch cord: such as MPO patch cord, suitable for scenarios where multiple optical fibers need to be connected simultaneously, such as high-density data center wiring.

4. Classification by wavelength

850nm patch cord: suitable for multimode optical fiber, used for short-distance transmission.

1310nm patch cord: suitable for single-mode optical fiber, used for medium-distance transmission.

1550nm patch cord: suitable for single-mode optical fiber, used for long-distance transmission, with lower transmission loss.

5. Classification by length

Short-distance patch cord: suitable for short-distance connection between servers and switches within the data center.

Long-distance patch cord: suitable for long-distance optical fiber connection across floors and buildings.

6. Classification by use environment

Indoor patch cord: suitable for indoor environments such as data centers and offices.

Outdoor patch cord: has higher waterproof, dustproof and tensile resistance, suitable for outdoor environments.

When choosing a fiber optic patch cord, you should choose the appropriate type of fiber optic patch cord based on the actual application scenario, transmission distance, connector type, fiber type, etc. to ensure the stability and performance of the network. At the same time, pay attention to the cleaning and maintenance of the patch cord to avoid contamination of the fiber end face that affects the signal transmission quality. (Source: Dongguan HX Fiber Technology Co., Ltd)
