FAQs on Fiber Optic Cable Singlemode and Multimode

Fiber optic cables are divided into single-mode and multi-mode. The fiber that supports a single mode is called single-mode fiber (SMF), and the fiber that supports multiple propagation paths or transverse modes is called multi-mode fiber (MMF). There are some questions about single-mode and multi-mode fiber optic cable users, ZR fiber will answer for you.

1. Are single-mode and multi-mode technologies produced at the same time? Which one is more advanced?

Single-mode and multi-mode are not the same as the more advanced ones. Generally, multi-mode is used for short distances, and only single-mode is used for far distances, because multi-mode fiber transceivers are much cheaper than single-mode ones. So, 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 fiber optic cables used in servers and storage devices single-mode or multi-mode?

Most servers and storage devices use multimode fiber optic cables.

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

Only single-mode can be used for long distances, but multi-mode is not necessarily required for indoor data transmission.

4. Do optical fibers have to be used in pairs?

Yes, generally they are used in pairs.

5. Is there any equipment such as single-hole single-mode fiber signal converter?

Does this question mean that the light is received and transmitted on one optical fiber? This is possible, and this is the case with China Telecom's 1600G backbone optical fiber network.
