What is the transmission rate of the multimode fiber connection method?

May 21, 2023

The transmission rate of a multimode fiber connection depends on a variety of factors, including the type of fiber, length, connector and light source. Under ideal conditions, multimode fiber connections can achieve transmission rates of billions of bits per second (Gbps) or higher.
Specifically, the transmission rate of a multimode fiber connection is affected by the following factors:
1. light source type: multimode fiber connection method generally uses LEDs or lasers as the light source, where lasers have a higher transmission rate and can achieve higher transmission rates.
2. Fiber type: multimode fiber is divided into two specifications: 50/125 micron and 62.5/125 micron, of which 50/125 micron fiber transmission rate is faster and can reach higher transmission rates.
3. fiber length: the longer the fiber, the slower the transmission rate will be, because the signal will be affected by attenuation and distortion in the transmission process. Therefore, the fiber length limitation needs to be considered when designing a fiber optic connection network.
4. Connector type: the quality and type of connector will also affect the transmission rate, a good connector can ensure a higher transmission rate.
5. fiber transmission mode: multimode fiber transmission mode is mainly divided into OM1, OM2, OM3, OM4 four, where OM3 and OM4 transmission rate is higher, can reach billions of bits per second (Gbps) or higher.

In summary, the transmission rate of multimode fiber connection mode depends on a variety of factors, but in practice, the transmission rate can usually reach several billion bits per second (Gbps) or higher, which is sufficient to meet the needs of most applications.
