Oh boy, an expanded attack surface for hackers! Transmission data traveling in the air or over fiber can be eavesdropped. These single fiber connections are not a random attack target compared to a highly protected, buried trunk line (containing 100s ~ 1,000s of discrete fibers) coming in to secured demarc or meet-me rooms inside office parks or buildings. In residential, hospital, office buildings or parks - a single fiber can be easily identified to the user(s) by a pro-hacker. Physical layer security is becoming more than isolated conversations than it has been.
