DWDM enables high-bandwidth, long-distance transmission, optimizing telecom and data center networks.

Dense wavelength-division multiplexing (DWDM) is an optical transmission technology that uses multiple wavelengths of light to combine several data streams onto a single optical fiber. DWDM is a subset of wavelength-division multiplexing (WDM) that typically uses the spectrum band within 1530nm and 1625nm, or more commonly the C-band and L-band, to input 40, 88, 96… Continue reading What is DWDM

The components of a traditional DWDM system consists of the transponder, multiplexer/de-multiplexer, optical add/drop multiplexers, and optical amplifiers.     Below is a high level overview of the process in which data is transmitted using DWDM and what each component’s function is within the system: 1. The data stream comes in via the router and is… Continue reading What are the DWDM Components?
