Frequently asked questions about single-mode and multi-mode fiber optic cables

2021-10-09

Fiber optic cables are divided into single-mode and multi-mode. The single-mode fiber is called single-mode fiber (SMF), and the fiber that supports multiple propagation paths or transverse modes is called multi-mode fiber (MMF). There will be some questions about fiber optic cable single-mode and multi-mode users. Today, Fiber Hope Fiber will answer everyone’s questions.


1. Are single-mode and multi-mode technologies produced at the same time? Is it more advanced?

Single-mode and multi-mode are not more advanced. Generally, multi-mode is used for short distances, and single-mode is used for far ones, because multi-mode fiber transceivers are   much cheaper than single-mode ones. Therefore, it is not to say that one of them is better and more advanced, but to choose different fiber optic cables according to different needs.

2. Are the fiber optic cables used for servers and storage devices single-mode or multi-mode?

Servers and storage devices mostly use multi-mode fiber optic cables.


3. Single-mode fiber is used for long-distance transmission, and multi-mode fiber is used for indoor data transmission, right?

Long-distance can only use single mode, but indoor data transmission does not necessarily use multi-mode.

4. Does the optical fiber have to be used one by one?

Yes, they are usually used one to one.


5. Are there any equipment such as single-hole single-mode fiber signal converters?

Does this question mean to receive and emit light on a fiber? This is possible, and China Telecom's 1600G backbone optical fiber network is like this.
