The major risk is the possibility of inserting a splitter into the optical distribution network and capturing a portion of the entire spectrum, i., all channels in the optical fiber. Another significant security risk is crosstalk on multiplexers in networks with wavelength. Optical fiber communications are essential for all types of long- and short-distance transmissions. While the costs associated with grey market, non-branded, or third-party vendors are extremely attractive to underfunded agencies, decision-makers must be aware of the. This paper will briefly discuss the history of fiber optics, explain the basics of fiber optic technologies and then discuss the vulnerabilities in fiber optic systems and how they can be better protected.
