Optical fiber is short for optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". As an excellent transmission medium for communication transmission, optical fiber communication has the characteristics of fast information transmission speed and large data information storage capacity.

Fiber optic patch cords and covered fiber optic cables are two types of fiber optic cables commonly used in fiber optic communications. They have significant differences in structure, performance and application.

1. Structure and appearance

Fiber jumper: Fiber jumper is a pre-terminated optical cable with standard fiber connectors such as LC, SC, ST, etc. on both ends. The core of this type of cable is usually pressed and formed by optical cable manufacturers such as POF or MTRJ, and then the connector is encapsulated on the outside. The appearance of the fiber jumper is usually round.

Leather fiber cable: Leather fiber cable is made of a bundle of bare optical fibers wrapped around a core, which is then covered with a protective sheath of PVC or LSZH material. It has a flat appearance, flat lines, and a width generally between 1.6mm and 4.5mm.

2. Materials and Performance

Fiber optic patch cord: The core of a fiber optic patch cord is usually made of pure quartz material, which has the characteristics of low loss and high bandwidth. Its connector is also precisely processed to ensure stable transmission of optical signals.

Leather fiber cable: The bare fiber part of the leather fiber cable is made of glass fiber, and is protected by a protective sheath of PVC or LSZH material. This type of optical cable has good bending performance and durability, and is suitable for indoor and outdoor environments.

3. Application Scenarios

Fiber optic patch cord: Since fiber optic patch cords have connectors at both ends, they can be easily connected to various devices. Therefore, they are widely used as connectors or patch cords in fiber optic communication networks to connect devices, fiber optic distribution frames, etc. In addition, fiber optic patch cords are also widely used in test equipment, local area networks and other fields.

Leather fiber cable: Leather fiber cable is mainly used in telecommunication networks, data transmission, radio and television networks, etc. Due to its flat appearance and good bending performance, leather fiber cable is particularly suitable for use in indoor wiring, equipment connection and other scenarios.

4. Customized specifications

The custom specifications of fiber optic patch cords and leather fiber optic cables are also different. The length of fiber optic patch cords is usually customized according to actual needs, and common specifications include 3 meters, 5 meters, etc.

The customized specifications of leather fiber optic cables are more flexible and can be customized to 3 meters, 5 meters, 10 meters, 20 meters, 30 meters, 40 meters, 50 meters, 60 meters, 80 meters, 100 meters, and 150 meters according to actual needs. , 200 meters, 300 meters, 500 meters, 800 meters and other different lengths.

There are significant differences between fiber optic patch cords and covered fiber optic cables in terms of structure, appearance, material, performance and application scenarios. Choosing the appropriate fiber optic patch cord or leather fiber optic cable needs to be decided based on actual needs and scenarios. In scenarios that require high bandwidth and low loss, fiber optic jumpers are a better choice; in scenarios that require good bending performance and durability, covered fiber optic cables have more advantages. Understanding the differences between these two types of optical cables can help us make more informed choices to better meet different communication transmission needs.
