US 2026/0280695 A1 · HOLLOW CORE FIBER-BASED OPTICAL NETWORK LINE SYSTEM WITH MULTIPLE MULTIPLEXED OPTICAL SUPERVISORY CHANNELS

Abstract

Systems and methods are provided for implementing a hollow core fiber (“HCF”)-based optical network line system with multiple multiplexed optical supervisory channels. In examples, a first transponder of an optical line system (“OLS”) receives a first optical data signal at a first signal wavelength range, amplifies the first optical data signal into a second optical data signal, and generates two or more optical supervisory channel (“OSC”) signals at corresponding two or more OSC wavelengths separate from the first signal wavelength range. The first transponder injects the two or more OSC signals in the second optical data signal, and transmits the second optical data signal to a second transponder over an HCF communicatively coupling the two transponders over a fiber path distance. The two or more OSC signals are subsequently extracted from the second optical data signal, and analyzed to identify potential issues and/or measure optical properties in the OLS.
