Wavelength Division Multiplexing Transmission Level
Normal WDM (sometimes called BWDM) uses the two normal wavelengths 1310 and 1550 nm on one fiber. Dense WDM (DWDM) uses the C-Band (1530 nm-1565 nm) transmission window but with denser channel. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. The "basie" transmission rate of SONET is 64 kbps for supporting voice communications. SONET multiplexes large numbers of 64-kbps channels onto higher-rate datastreams. SONET defines a. Wavelength division multiplexers are fundamental to the functioning and performance of integrated photonic circuits, with applications ranging from optical interconnects to sensing and quantum technologies.

Fiber Optic Grating Liquid Level Measurement
In this paper, we present a polymer optical fiber (POF) Bragg grating (FBG) to measure liquid level based on Archimides' law of buoyancy. The sensor consists of polymer 3D-printed rods with different radii attached to the fiber terminal containing an FBG. When the temperatures of the liquid and the gas are different, the liquid level can be. In this paper, we present a fiber sensor using a fiber Bragg grating encapsulated in a half-polymer-filled metal cylinder for measuring liquid level variation.
