Enhancing FSO‐DWDM Performance Through Compensation Strategies
Engineering Reports, Volume 7, Issue 12, December 2025.This study investigates the performance of free space optics (FSO) with dense wavelength division multiplexing (DWDM) systems, focusing on the impact of channel number and compensation strategies on bit error rate (BER). Results show that post‐compensation significantly improves performance, extending the system's range from 3 to 5 km.

xLED: Covert Data Exfiltration from Air-Gapped Networks via Router LEDs
, 2017 In this paper we show how attackers can covertly leak data (e.g., encryption keys, passwords and files) from highly secure or air-gapped networks via the row of status LEDs that exists in networking equipment such as LAN switches and routers. Although it
