Why Experts Prefer The 2µm Laser Module For Optical Networking?

 

As a new and emerging technology, the 2µm laser module has been gaining considerable attention due to its application in modern communication systems. This wavelength is becoming increasingly substantial as conventional communication wavelength spectrum bands continue to become more crowded, and limitations arise.

 

1)     Enhanced bandwidth options in the 2µm band

 

Another compelling reason experts prefer the 2µm laser module is the greater bandwidth availability in this region of the spectrum. The 2µm window has ample spectral availability to support appropriate high-speed networks with one or more bottlenecks. Shifting to the 2µm region will still be broadband spectrum but will be cleaner and more future-proof, with ample room for expansion.

 

2)     Lower losses of new fiber materials

 

Advancements in fiber technology make the 2µm band much more appealing. New hollow-core fibers as well as thulium-doped fiber materials have exhibited excellent to better performance in the 2µm band, including lower attenuation in fiber and non-linear effects. This means that data can be transmitted over longer distances stably and more efficiently with the high power 2µm laser.

 

3)     Advantageous ocular safety and higher power handling

 

Another consideration behind interest from experts in the field is the better safety profile of the 2μm wavelength. Light at this wavelength is absorbed more efficiently by water in biological tissues, and this translates to minimal risk for deep-tissue absorption. Thus, a 2µm laser module can accommodate higher power levels with confidence that the operator is safe.

 

4)     Less interference

 

The 2micron fiber laser module also has advantages associated with optical clarity and signal fidelity. Networks operating in this wavelength regime have fewer issues with interference (as the 2μm window has not yet been crowded by commercial systems and legacy infrastructure). Hence, there is less distortion, allowing for a cleaner data stream, particularly at higher bit rates.
