The difference between single-mode fiber jumpers and multi-mode fiber jumpers

Fiber optic communication technology is an important part of the modern communication field, and fiber jumpers, as an important component in the fiber optic communication system, play a vital role in the transmission quality and stability of the entire system. In the selection of fiber jumpers, single-mode fiber jumpers, and multi-mode fiber jumpers are two common choices. This article will introduce the difference between single-mode fiber jumpers and multi-mode fiber jumpers in detail.

Fiber jumpers, also known as fiber optic connectors, are transparent soft wires used to connect fiber optic equipment or fiber distribution frames. It consists of fiber core, cladding, sheath, and connector, and is mainly divided into single-mode fiber jumpers and multi-mode fiber jumpers according to the transmission mode.

The main difference between single-mode fiber jumpers and multi-mode fiber jumpers

1. Transmission mode:

Single-mode fiber jumpers use single-mode optical fiber and only allow one mode of light to pass, that is, the core mode of straight-line propagation. This propagation mode reduces mode dispersion, making single-mode optical fiber suitable for long-distance transmission.

Multimode fiber jumpers use multi-mode optical fiber, allowing multiple modes of light to propagate simultaneously. This multi-mode transmission leads to mode dispersion and is suitable for short-distance transmission.

2. Core diameter and numerical aperture:

Single-mode fiber has a smaller core diameter, usually 9 to 10 microns, and a lower numerical aperture, which helps reduce signal diffusion and increase transmission distance.

Multimode fiber has a wider core, usually 50 or 62.5 microns, and a larger numerical aperture, which can more easily receive optical signals, but will cause more dispersion.

3. Light source and wavelength:

Single-mode fiber jumpers often use laser diodes as light sources, and the wavelength is usually 1310nm or 1550nm, which helps reduce signal loss.

Multimode fiber jumpers can use LEDs or laser diodes as light sources, and the commonly used wavelengths are 850nm or 1300nm.

4. Bandwidth and distance:

Due to the low dispersion characteristics, single-mode fiber jumpers provide higher bandwidth, suitable for high-speed data transmission and long-distance transmission, up to tens of kilometers.

Multimode fiber jumpers have lower bandwidth due to their higher dispersion and are generally used for short-distance transmissions, such as connections within local area networks or data centers.

5. Cost and installation:

Single-mode fiber jumpers are more expensive, and installation and maintenance require more precise equipment and technology.

Multi-mode fiber jumpers are relatively cheap, and installation and maintenance are simpler and faster.

6. Application scenarios:

Single-mode fiber jumpers are mainly used in long-distance transmission scenarios in telecommunications and wide-area networks.

Multi-mode fiber jumpers are more suitable for short-distance applications such as data centers and internal networks.

In summary, single-mode and multi-mode fiber jumpers have their own characteristics and applicable fields. Single-mode fiber jumpers perform well in high-speed and long-distance transmission requirements with their extremely low dispersion and loss characteristics. Multi-mode fiber jumpers are widely used in short-distance transmission due to their lower cost and simple installation methods. When choosing fiber jumpers, users should consider factors such as actual network layout, transmission distance, and budget to ensure the optimal configuration and efficient operation of the communication system.
