Currently, utilizing WDM technology to deploy the optical network has received widespread attentions, which enables higher capacity for data transmission. However, the technology is also limited by the transmission distance. When deploying a long WDM system, the signal power would still become weak due to the fiber loss. In order to address the issue, using EDFA amplifier to directly enhance the WDM signals would be a good choice for current and future optical network needs. The optical network combining WDM technology and EDFA module together can transmit multiple signals over the same fiber, at lengths up to a few hundred kilometers or even transoceanic distances. To better know how does EDFA amplifier work in the long WDM system, let’s learn the EDFA amplifier knowledge and analyze the performance of WDM system bonding with the EDFA module.

Introduction to EDFA Amplifier

EDFA amplifier, also referred to as erbium-doped fiber amplifier, is basically composed of a length of Erbium-doped fiber (EDF), a pump laser, and a WDM combiner. When it works, the pump laser with 980 nm or 1480 nm and the input signal around 1550 nm can be combined by the WDM combiner, then transmitted and multiplexed into the Erbium-doped fiber for signal amplification. The pump energy can be transmitted in the same direction as the signal (forward pumping), or the opposite direction to the signal (backward pumping), or both direction together. And the pump laser can also using 980 nm or 1480 nm, or both. Taking the cost, reliability and power consumption into account, the forward pumping configuration with 980nm pump laser EDFA amplifier is always the first choice to enhance the signals for a long WDM system.

Analysis of WDM Network Without EDFA Amplifier

Before analyzing WDM network deployed with EDFA amplifier, it is necessary to know the basic configuration of an original WDM network, as shown in the figure below. We can learn that four signals from different channels are combined by the optical combiner. And then, the integrated signals are transmitted through an optical fiber. Thirdly, the signals are split into two parts by the splitter. One part passes through the optical spectrum analyzer for analyzing signals, and the other one goes through the photo detector to be converted into electrical signal and then be observed by the electrical filter and scope. However, in the process, the signal power gets highly attenuated after being transmitting at long distance.

Analysis of WDM Network Using EDFA Amplifier

By using the EDFA amplifier, we can easily overcome the attenuation of long WDM network. From the following figure, we can learn that EDFA amplifiers act as booster amplifier and pre-amplifier to enhance the signal, so that system will no longer suffer from losses or attenuation. Therefore, if you need to deploy a long WDM system, it is highly recommended to deploy the EDFA amplifiers in the system that features flat gain over a large dynamic gain range, low noise, high saturation output power and stable operation with excellent transient suppression. It is an undoubtedly ideal solution with reliable performance and relatively low cost to extend the WDM network transmission distance.

Conclusion

It is well know that the signal power would be greatly attenuated when the transmission distance is long enough. Hence, when deploying a long WDM network, it is definitely necessary to use the EDFA amplifier to enhance the signal strength, allowing for the long transmission distance. As a preferable option, the EDFA amplifier with very low noise is relatively insensitive to signal polarization and easy to realize signal amplification.

In today’s world, communication technology is rapidly advancing, and the demand for high-quality and reliable data transmission is increasing. As a result, polarization maintaining cables have emerged as an essential component in optical fiber communication systems. These cables are designed to maintain the polarization of light waves as they travel through the cable, thereby improving the accuracy and reliability of the transmission.

What is Polarization Maintaining Cable?

A polarization maintaining cable, also known as a PM cable, is a type of optical fiber cable that is designed to maintain the polarization state of light waves as they travel through the cable. Polarization refers to the orientation of the electric field vector in a light wave, which can be horizontal, vertical, or any angle in between. When light travels through a regular optical fiber, its polarization state can change due to various factors, such as temperature changes, bending of the fiber, and stress on the fiber.

How does it work?

A polarization maintaining cable consists of a single-mode optical fiber that has been specially designed to maintain the polarization state of light waves. The fiber has a core that is surrounded by a cladding layer, which is made of a material that has a different refractive index than the core. In a PM cable, the cladding layer is elliptical in shape, which creates two perpendicular axes of polarization in the fiber.

The light wave is launched into the fiber through a polarization-maintaining connector, which aligns the orientation of the wave’s electric field with one of the fiber’s axes of polarization. As the wave travels through the fiber, its polarization state is maintained by the elliptical shape of the cladding layer, which creates a birefringent effect. This means that the wave travels at different speeds along the two axes of polarization, which keeps its polarization state constant.

Applications of Polarization Maintaining Cable

Polarization maintaining cables are used in a wide range of applications that require high precision and reliability, such as in fiber optic gyroscopes, optical sensors, and coherent communication systems. They are also used in biomedical imaging and laser machining, where the accuracy and consistency of the polarization state are critical.

Conclusion

In summary, polarization maintaining cables are an essential component in optical fiber communication systems, providing high precision and reliability in data transmission. Their ability to maintain the polarization state of light waves as they travel through the cable makes them a vital tool in a wide range of applications that require accurate and consistent polarization. As communication technology continues to evolve, the demand for polarization maintaining cables is only set to grow.
