Number of bits transmitted per second
- Bit rate, also known as data rate, is a fundamental measurement of the number of bits transmitted per second over an optical fiber link. It quantifies the volume of data that can be transferred through the fiber optic channel within a given timeframe.

After a period of research starting from 1975, the first commercial fiber-optic telecommunications system was developed which operated at a wavelength around 0.8 μm and used GaAs semiconductor lasers. This first-generation system operated at a bit rate of 45 Mbit/s with repeater spacing of up to 10 km.
In modern optical fiber communications, maximizing data transmission efficiency while minimizing signal degradation is crucial. Several key parameters such as baud rate, bit rate, and spectral width play a critical role in determining the performance of optical networks.

Motivated by the worldÕs growing need for communication band-width, progress is constantly being reported in building newer optical fibers that are capable of handling the rapid increase in traf-fic. However, building an optical fiber link is a major investment, one that is very expensive to replace. For example, the optical fiber cables that were ...

Attenuation in fiber occurs due to absorption, scattering and radiative losses of the optical energy. Absorption losses are caused by atomic defects in the glass composition, intrinsic absorption by atomic reso-nance of fiber material and extrinsic absorption by the atomic resonance of external particles (like OH ion) in the fiber. Scattering losse...
For high-speed optical fiber communication, the data transmission reli-ability can be degraded by some or all of the system impairments, mentioned earlier, resulting in a quality of service that is lower than that demanded by the system specifications. In this case, the transport proto-col of the network can be manipulated to compensate for the los...
Although the term equalization derives from linear filter theory, it now applies to any scheme aimed at compensating for the effects of a disper-sive channel. Equalizers are classified into three general types [14]. One is based on the maximum-likelihood sequence estimation (MLSE) crite-rion which provides the best performance. The second type is b...

Although equalization is very well known in lower rate communica-tion systems, its potential in Gb/s optical communication has not been fully exploited yet. The main obstacle lies in the very high speed implementation requirements which limit the available options for implementation. The effectiveness of linear equalizers, which are the simplest an...

Abstract—The bit error rate (BER) is the percentage of bits that have errors relative to the total number of bits received in a transmission. The different modulation techniques scheme is suggested for improvement of BER in fiber optic communications.
The bandwidth per wire is generally less than ~0.1 GHz for distances between amplifiers of 1 km, whereas a single optical fiber can convey ~1 THz for 100 km or more.
