Wavelength
What Does Wavelength Mean? Wavelength refers to the length or distance between two identical points of neighboring cycles of a wave signal traveling in space or in any physical medium. The length is measured in distance specifications such as meters, centimeters or millimeters. The wavelength of a signal is inversely proportional to its frequency, that […]

Coarse Wavelength Division Multiplexing
What Does Coarse Wavelength Division Multiplexing Mean? Coarse wavelength division multiplexing (CWDM), a variant of wavelength division multiplexing (WDM), is an optical transmission technique used for shorter distances as compared to dense WDM (DWDM). CWDM transmits few channels and makes use of wider spacing in between the channels for distances of up to 60 km. […]

Wavelength Division Multiplexing
What Does Wavelength Division Multiplexing Mean? Wavelength division multiplexing (WDM) is a technology or technique modulating numerous data streams, i.e. optical carrier signals of varying wavelengths (colors) of laser light, onto a single optical fiber. WDM enables bi-directional communication as well as multiplication of signal capacity. WDM is actually frequency division multiplexing (FDM) but referencing […]

Dense Wavelength Division Multiplexing
What Does Dense Wavelength Division Multiplexing Mean? Dense wavelength division multiplexing (DWDM) is wavelength division multiplexing (WDM) with typical channel spacing of 100 GHz for 40 channels and 50 GHz for 80 channels. Each channel contains a TDM (time division multiplex) signal. And each of up to 80 channels can carry 2.5 Gbps for a […]

Metropolitan Area Network
What Does Metropolitan Area Network Mean? A metropolitan area network (MAN) is similar to a local area network (LAN) but spans an entire city or campus, or some other municipal or organizational territory. MANs are formed by connecting multiple LANs. Thus, MANs are larger than LANs, but smaller than wide area networks (WAN) that cover […]

Infrared and 3D Sensing: How Machines Are Learning Human Senses
Rudimentary infrared products and applications, recognizable by their characteristic red lights that respond to gestures, are a familiar sight to many. Touchless household garbage cans that open on their own in response to hand gestures and autonomous robotic household vacuum cleaners that dodge walls and other barriers, or even recharge on their own, are examples […]

Next-Gen Encryption to Confront Next-Gen Threats
The digital underworld is employing increasingly sophisticated technologies to penetrate enterprise infrastructure, but in the continual game of one-upmanship new encryption technologies to thwart these efforts are emerging from the lab at a steady clip. In this never-ending battle, however, we can expect to see occasional victories on both sides, so the question for data […]
