The rapid growth of Internet connections is straining data communication networks' capabilities and calling for organic inter connection of global communications infrastructure. To deliver more dynamic and flexible communication network of optical fibres, and various tion topologies optical add-drop multiplexers, for example, optical cross-connect systems and (OADMs) (OXCs) are being created to incorporate many optical networks Also, Tera b/s data transmis - Plans for sions per fibre in the near future. Advanced integration of time-division multiplex (TDM) and wavelength-division multiple (WDM) signal transmission schemes is practical; thus, the demand for more capacity can be met by denser WDM channels and faster TDM channels.
Once upon a time, optical fibres appeared to have an almost unlimited capacity, and system speeds of up to 2.4 Gb/s could match the rates of both rapid electronic circuits and optical devices. However, with the introduction of 10 Gb/s systems, fibre dispersion and fibre non-linearity have increased to the point where they can fatally distort transmission waveforms, and the faster TDM systems see an abrupt decrease in transmission speed and range. The technical challenge of these limits is now unavoidable in high-speed TDM transmission systems. Fiber self-phase modulation (SPM) limits transmitter output power. Because of the degradation of receiver sensitivity due to the noise bandwidth in high-speed systems, the power level margin is insufficient for long- distance fiber loss. The introduction of optical fiber amplifier repeaters and optical power management along the fibers has dramatically increased the transmission distance. extreme fibre chromatic dispersion distortion of the transmission waveform in high-constraints on speed systems as a result. the distance and speed of transmission [1-3].
The installed fibre constant determines restrictions.optical wave-length, transmission distance, and length. Each band in multi-band WDM systems uses channels suffer from a different fiber's wavelength dispersion, therefore each channel must compensate tion might be necessary. Polarization-Mode Dispersion (PMD) also restricts transmissions depending on the fiber features, optical components, and other environmental stress factors. Conventionally installed fibers, which have a large PMD constant, even degrade 10 Gb/s transmis-sions. In order to decrease system complexity and simplify the installation, it is crucial to reduce the size and cost of all WDM channel equipment in WDM systems and other network applications that use multiple optical wavelength channels. Installing 10 Gb/s systems as fundamental integration channel units and using them as network resources will be necessary. It will be especially helpful to reduce the size and cost of the fiber components of 10 Gb/s equipment as well as the electronic circuits.
The size, power, and cost of TDM transmitters and receivers are all reduced because to the integration of electronic circuits. In turn, this makes it possible to install tiny WDM channels and eliminates the need for expensive, complicated equipment. Compound semi-conductors with greater speed performance can be employed to speed up circuits for 10 Gb/s operation. For speed and reliability, we have used InGaP/GaAs hetero-junction bipolar transistor integrated circuits (HBT-ICs). These transistors' high-gain profiles allow high-gain, high-frequency amplifiers (preamplifiers and slice amplifiers), as well as high-sensitivity, high-speed decision circuits, to operate steadily and effectively. Even in 10 Gb/s systems, dispersion compensating fibres (DCFs) and fibre amplifiers are frequently utilised to get around the fibres' limitations in terms of transmission speed. But because these components require long fibres, they are too large for network equipment. In order to achieve compactness in network connectivity installations without compromising speed or range, fibre components must be removed [4,5].
