Abstract: High data rates can be achieved using DWDM technology over optical fiber. Optical signals having different frequencies are modulated in DWDM system and then these signals are multiplexed ...

Abstract: Dense wavelength division multiplexing (DWDM) is an optical technology that allows transmitting across a fiber many wavelengths, which can be added and dropped by means of passive optical ...

A resurfacing iPhone bug is leaving alarms technically "on" but functionally silent, catching users off guard at the worst possible time. Here's how you can (usually) avoid the same fate. Imagine if ...
