Totalplay / D1 / WDM Basics

The chromatic​​ (a)   is the phenomenon by which a ​ (b)   separates white light into various beams of monochromatic light.

• dispersion
• prism
• attenuation
• splitter

The electromagnetic ​ (a)   is the arrangement of electromagnetic ​ (b)   according with their ​ (c)   or​ wavelength; where we can find invisible signals like x-rays, ​ (d)   or even visible light where we can find the​ (e)   such as red, orange, yellow, green, cyan, blue and purple.

• colors
• waves
• frequency
• infrared light

This acronym refers to the technology that is able to transmit multiple service signals with multiple wavelengths over one single optical fiber:

Match the following

• Polarization Mode Dispersion (PMD)

• The time delay difference resulting from different modes (incident angles) that have different group velocities

• Chromatic Dispersion (CD)

• The time delay difference resulting from different propagation velocities of two optical signals with different cross polarization states

• Intermodal Dispersion

• The dispersion generated by the different time delays from different signals with different frequencies (or wavelengths) during their transmission over the same optical fiber

Match the following

• G.653

• This fiber is called dispersion shifted fiber (DSF). It has zero-dispersion at 1550nm to match the minimum attenuation window of the fiber. But it has strong non-linear effects.

• G.652

• This fiber is the widely used single-mode fiber (SMF). It has around of 17 ps/nmkm at 1550nm. It is also called dispersion-unshifted fiber.

• G.655

• This fiber is also know as non-zero dispersion shift (NZDSF). Therefore, there is certain dispersion of around 4 ps/nmkm at 1550nm that is close to the one of G.653 but without the problem of strong non-linear effects.

Please order the following modulations from lower to higher capacity

• QPSK
