  • Interference Resistance of Fiber Optic Communication

    Interference Resistance of Fiber Optic Communication

    Fiber optic networks are highly resistant to external electromagnetic interference. This is because signals propagate through light rather than electrical current inside the fiber. (FSI), we leverage our expertise in fiber optic technology to address the challenges of signal interference. Fiber optic cables are essential components in modern data transmission infrastructure. They support high-speed, interference-resistant communication and are particularly effective in applications that require high bandwidth, low latency, and strong signal integrity. We investigate this in two numerical simulation models: 1) an additive white Gaussian noise (AWGN) channel wit bandwidth limitation and 2) an intensity modulated direct. This paper presents how different tests of throughput and latency were carried out using Viavi test kit, analyzed and then after compared the obtained results with the standard defined by IEEE and ITU for conformity. Some of the results conformed with the defined whereas others did not because of.
