Optical fiber patch cord type

Fiber patch cords are important connecting parts in optical communication systems, and are mainly divided into single-mode and multi-mode types.

single mode fiber patch cord

Single-mode fiber jumpers use single-mode fiber with a thin core, usually only 9 microns. Single-mode fiber jumpers can support long-distance signal transmission and are generally suitable for scenarios such as long-distance backbone networks and metropolitan area networks. Since it only allows one mode of optical signal transmission, the signal attenuation is small, the transmission bandwidth is high, and high-speed and large-capacity data transmission can be achieved.

Multimode fiber patch cord

Multimode fiber jumpers use multimode fibers with relatively thick cores, commonly 50 microns and 62.5 microns. Multimode fiber jumpers are suitable for short-distance transmission and are often used for network connections within buildings, such as office local area networks. It allows multiple modes of optical signals to be transmitted in the core, but the signal transmission distance is relatively short and the bandwidth is relatively low.

Optical fiber jumper selection

Transmission distance consideration

When selecting fiber optic jumpers, the transmission distance is a key factor. If long-distance transmission is required, single-mode fiber optic jumpers are a better choice, which can achieve signal transmission of tens of kilometers or even hundreds of kilometers. For short-distance connections, such as within a few hundred meters, multi-mode fiber optic jumpers can meet the demand, and the cost is relatively low.

bandwidth requirements considerations

Different application scenarios have different requirements for bandwidth. If it is high-speed data transmission, such as the internal connection of the data center, you need to choose a fiber optic jumper with a higher bandwidth. Single-mode fiber jumpers have advantages in bandwidth and can support 10G, 40G or even higher rates. Multimode fiber jumpers are also constantly developing, and new multimode fiber jumpers can also meet certain high-rate requirements.

Connector type selection

There are many types of connectors for fiber optic jumpers, the common ones are SC, LC, FC, etc. SC connectors are easy to plug and unplug and are often used in fiber optic transceivers and other equipment; LC connectors are small in size and suitable for high-density fiber optic connection scenarios; FC connectors have better sealing and are often used in some occasions with high environmental requirements.

Fiber Patch Settings

Preparation

Before setting up the fiber jumper, you need to prepare relevant tools and materials, such as fiber stripping pliers, fiber cutting knives, fiber welding machines, etc. At the same time, ensure the compatibility of the fiber jumper and connecting equipment.

Installation steps

First, the outer skin of the fiber jumper is carefully peeled off using fiber stripping pliers. Then, the end face of the fiber is cut flat with a fiber cutting knife. Then, the cut fiber is put into the fiber welding machine for welding operation. Finally, the welded fiber jumper is connected to the corresponding equipment.

Testing and Inspection

After the installation is completed, the fiber jumper should be tested and inspected. Optical power meters and other equipment can be used to test the strength and attenuation of the optical signal to ensure that the connection of the fiber jumper is normal and the signal transmission is stable.

Optical fiber jumper performance optimization

cleaning and maintenance

Regularly cleaning the connectors and end faces of fiber optic jumpers can effectively reduce the impact of dust and impurities on optical signal transmission. Cleaning with dedicated fiber optic cleaning tools can improve the performance and service life of fiber optic jumpers.

reasonable wiring

Reasonably plan the wiring of fiber optic jumpers to avoid excessive bending and extrusion. The bending radius of fiber optic jumpers should not be too small, otherwise it will affect the transmission quality of optical signals.

temperature control

Keep the temperature of the environment where the fiber jumper is located stable. Too high or too low temperature will affect the performance of the fiber jumper. Especially in high temperature environments, the attenuation of the fiber will increase, affecting signal transmission.

Everyone is asking:

1. What is the difference between single-mode fiber patch cords and multimode fiber patch cords?

The single-mode fiber jumper has a thin core, suitable for long-distance, high-speed, and large-capacity transmission; the multimode fiber jumper has a thick core, suitable for short-distance transmission, and the cost is relatively low.

2. How to choose the right fiber optic jumper connector?

According to the device type and application scenario selection, the SC connector is easy to plug and unplug, the LC connector is small in size, and the FC connector has good sealing performance.

3. What preparations do I need to make before setting up the fiber patch cable?

Prepare the fiber stripper, fiber cutter, fiber fusion machine and other tools to ensure the compatibility of fiber jumpers and connecting devices.

4. How to optimize the performance of fiber optic patch cords?

Regularly clean the connectors and end faces, properly route, and maintain a stable ambient temperature.

5. What factors affect the transmission distance of fiber optic jumpers?

It is mainly influenced by factors such as the type of fiber (single-mode or multi-mode) and the attenuation of the optical signal.
