Network Cabling guide: Basic knowledge of optical fiber to improve literacy

This content is nothing for experienced friends, but it can be useful for new users who just entered the industry.

There are two types of optical fibers:

Single-mode Optical Fiber Single-mode Fiber): Generally, the optical Fiber jumper is yellow, the connector and protective sleeve are blue, and the transmission distance is long.

Multimode Optical Fiber Multi-mode Fiber): Generally, optical Fiber Jumpers are orange, and some are gray. The connector and protective sleeve are beige or black. The transmission distance is short.

SC SC-ST LC

Optical fiber usage notes!

The optical modules at both ends of the optical jumper must have the same sending and receiving wavelength. That is to say, the two ends of the optical fiber must be optical modules with the same wavelength. A simple distinction is that the color of the optical modules must be consistent.

Generally, the short-wave optical module uses multi-mode optical fiber orange optical fiber, and the long-wave optical module uses a single-mode optical fiber yellow fiber) to ensure the accuracy of data transmission.

Do not bend or bypass the optical fiber during use, which will increase the attenuation of the light during transmission.

After the optical jumper is used, you must use a protective cover to protect the Optical Fiber Connector. Dust and oil stains may damage the coupling of the optical fiber.
