Is the general fiber patch cord multimode?

　　Fiber Patch Cords do not have to be multimode, they can also be single-mode. The mode of fiber patch cords (single-mode or multimode) mainly depends on the type of fiber inside it.

　　single mode fiber patch cord

　　Features: Only one mode of light is allowed to propagate. The core diameter is SMall, generally about 9μm, and the cladding diameter is 125μm. The transmission distance is long, suitable for long-distance communication.

　　Application: Mainly used in long-distance, backbone, and metropolitan area networks.

　　Multimode fiber patch cord

　　Features: Allows multiple modes of light to propagate simultaneously. The core diameter is relatively large, and there are two common types: 50μm and 62.5μm, and the cladding diameter is also 125μm. The transmission distance is short, generally around a few hundred meters to 2 kilometers.

　　Application: It is widely used in short-distance, high-bandwidth local area networks (such as enterprise office networks, campus networks, etc.).

　　Distinction method

　　Color: Generally, single-mode fiber optic jumpers are indicated in yellow, and connectors and protective covers are blue; multimode fiber jumpers are generally indicated in orange, and some are indicated in gray. Connectors and protective covers are beige or black.

　　Transmission performance: Single-mode fiber jumpers have a longer transmission distance and are suitable for application scenarios that require long-distance transmission; while multi-mode fiber jumpers have a shorter transmission distance but higher bandwidth, making them suitable for application scenarios with short-distance and high bandwidth requirements.

　　In summary, fiber optic jumpers can be single-mode or multi-mode, depending on the application scenario and requirements. When selecting fiber optic jumpers, the appropriate type should be selected according to the actual needs and application scenarios.
