This arrangement can best be studied by using comparison of eye-diagrams and bit-error-rate (BER) analysis of the system operation as the laser wavelength is detuned.
Most modern systems, including computers, smartphones, Wi-Fi, and fiber-optic internet, rely on digital communication because it is easier to store, process, encrypt, and correct for errors.
In these types of systems the errors are (for the most part) caused by either intrinsic or extrinsic noise sources that can affect any or all parts of a data link. The measurement and specification of a bit

We design the dense WDM system signals at central wavelengths in the area of 1550 nm. This method offers almost negligible dispersion by reducing the jitter portion in Eye diagram. This method also
Signal degradation is a primary cause of BER in optical communications. Attenuation, or signal loss, occurs as light travels through the fiber optic cable, reducing the signal''s intensity.
Even a digital data transmission system is not totally error-free — statistical fluctuations related to noise influences cause a small percentage of the transmitted bits to be corrupted. The average fraction of
