What You Need to Know About Fiber Optic Cable Patch Cords

Fiber optic cable patch cords are used to connect devices to fiber optic cabling links. They have a thicker protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

I、Classification of Fiber Patch Cords

There are also many types of fiber optic cable patch cords (also known as fiber optic connectors), which are fiber optic connectors that connect to optical modules, and they are not interchangeable. SFP modules connect to LC fiber optic connectors, while GBIC connects to SC fiber optic connectors. On the Fibermart website, you can find the fiber optic patch cord you want. The following is a detailed description of several commonly used fiber optic connectors in network engineering:

1、FC Type Fiber Patch Cord

The external reinforcement method is to use a metal sleeve, and the fastening method is a screw buckle. The head is a metal connector, which is generally used on the ODF side. The metal plug head can be plugged in more times than the plastic one. It is mostly used in telecommunications networks. There is a nut screwed onto the adapter. The advantage is that it is firm and dustproof, but the disadvantage is that the installation time is slightly longer.

2、SC Type Fiber Patch Cord

This type of fiber optic cable patch cord is commonly used in fiber optic patch panels. The outer shell is round and the fastening method is screw buckle. It is made of engineering plastics, resistant to high temperature and not easy to oxidize. The side optical interface of the transmission equipment generally uses SC connector, which is directly plugged in and out, and is very convenient to use, but the disadvantage is that it is easy to fall out.

3、ST Type Fiber Patch Cord

Commonly used in optical fiber distribution frames, the outer shell is round and the fastening method is screw buckle. Commonly used in general networks, the ST head is inserted and rotated half a circle to be fixed with a bayonet. The disadvantage is that it is easy to break.

4、LC Type Fiber Patch Cable

The connector for connecting SFP modules is made of a modular jack latch mechanism that is easy to operate and is commonly used in routers. The LC connector is similar in shape to the SC connector, but smaller than the SC connector .

II、The Important Role of Fiber Optic Patch Cord

Fiber patch cable play a vital role in the field of modern communications. As accessories for connecting fiber optic devices, fiber optic cable patch cords have the characteristics of fast transmission, low signal loss, long transmission distance, safety and stability, high adaptability and easy maintenance. According to different transmission requirements and network environments, users can choose fiber patch cords of different types and specifications to achieve efficient, stable and safe data transmission and communication services.

1、Connecting Fiber Optic Equipment

Fiber patch cords are usually used to connect two fiber optic devices, such as connecting a fiber optic terminal box and a fiber optic switch.

2、Transmitting Optical Fiber Signals

Fiber patch cords can transmit high-speed fiber optic signals and are usually used for long-distance fiber optic transmission, such as connecting two computer rooms.

3、Expanding Fiber Optic Networks

When you need to add new fiber optic equipment to an existing fiber optic network, you can use fiber patch cords to connect the new equipment to the existing fiber optic network .

4、Improving the Reliability of Fiber Optic Cable Patch Cords

Using fiber optic cable patch cords can reduce signal attenuation and noise interference in fiber optic transmission, thereby improving the reliability of the fiber optic network.

5、Adapt to Different Network Environments and Transmission Requirements

Fiber patch cords can adapt to different network environments and transmission requirements, such as multi-mode, single-mode, BIDI and other different types of patch cords, as well as patch cords with different lengths and connector types, to meet various user needs .

III、Precautions for Using Optical Fiber Jumpers

l The optical modules at both ends of the fiber jumper must be consistent, that is, the wavelengths of the optical modules at both ends of the fiber must be consistent. A simple way to distinguish is to use optical modules of the same color. Generally speaking, short-wave optical modules use multimode optical fibers (orange optical fibers) and long-wave optical modules use single-mode optical fibers (yellow optical fibers) to ensure the accuracy of data transmission.

l Do not bend or wrap the optical fiber excessively during use, as this will increase the attenuation of light during transmission.

l After using the fiber jumper, be sure to protect the optical fiber connector with a protective cover. Dust and oil will damage the coupling of the optical fiber.

l If the optical fiber connector is dirty, you can wipe it with a cotton swab dipped in alcohol, otherwise it will affect the communication quality.

Conclusion

In fact, fiber jumpers are generally a type of transmission medium used between devices. Fiber jumpers are not only simple accessories for connecting fiber optic devices, but also a key factor in ensuring the efficient and stable operation of communication networks. Fiber jumpers are actually shorter communication optical fibers, but because the distance between two fiber optic communication devices is short, they are called fiber optic patch cords. In daily use, the most important thing to pay attention to is their model, because different models have different functions. If you need, please refer to this article and hope it can help you.
