A high-speed optical star network using TDMA and all-optical demultiplexing techniques [PDF]

, 1996
The authors demonstrate the use of time-division multiplexing (TDM) to realize a high capacity optical star network. The fundamental element of the demonstration network is a 10 ps, wavelength tunable, low jitter, pulse source. Electrical data is encoded

OTDR Aided Assessment of Fiber-Induced WDM Spectrum Unflatness

IEEE Access
The imperatively excellent performance of wavelength-division multiplexing (WDM) transmission over a fiber optic link, demands flat, i.e. not wavelength-selective transfer function. This implies that, mostly during installation and commissioning of a WDM-

Dynamic Search‐Based Cluster Head Selection Method for Resource Occupation Protection Switching in Optical Fiber Communication Networks

Engineering Reports, Volume 8, Issue 6, June 2026.
This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.

Pulse pedestal suppression using four-wave mixing in an SOA [PDF]

, 2008
Experimental results are presented demonstrating how four-wave mixing in a semiconductor optical amplifier can be used to remove pulse pedestals introduced due to nonlinearities which occur upon pulse propagation in an optical system.
