The essential requirements for establishing a low-loss and high-speed telecommunication line using optical fibers are high performance and quality splicing technology. The simple connection of optical fibers using optical connectors and mechanical splices is increasing. However, the fusion splice is needed for long-haul and high-capacity trunk communications such as submarine optical fiber cabl...

Optical technologies form the key foundations for transport networks used by all major telecommunication carriers. Those networks are made up of equipment supplied by different manufacturers, and utilize different optical switching and transmission technologies. These give rise to distinct islands or "domains" of network nodes of different capabilities. Further, administrative segmentation of n...

With the increasing frequency of natural disasters and intentional attacks that challenge telecommunication networks, vulnerability to cascading and regional-correlated challenges is escalating. Given the high complexity and large traffic load of optical networks, these correlated challenges cause substantial damage to reliable network communication. In this paper, we propose a network vulnerab...

n this essay, we present design and simulation of a Leakage detection and alocation of oil pipelines system using sensing the temperature distribution of optical fiber by COMSOL Multiphysics software. In this system, telecommunication single-mode optical fiber, 200 m typical length is used, in 1.55 μm electromagnetic wave. The proposed system, uses of Brillouin frequency shift occurred on fiber...

In this work we have designed a Mach Zehnder interferometer (MZI) for electro optic modulator at telecommunication wavelength using GaN on Sapphire. The knowledge of GaN sample optical properties were also investigated, resulting refractive index for the GaN layers were found to be nTE=2.279±0.001 and nTM = 2.316±0.001 and good temperatur stability. Optimization of the structure parameters and ...

We demonstrate optical 2R regeneration in an integrated silicon device consisting of an 8-mm-long nanowaveguide followed by a ring-resonator bandpass filter. The regeneration process is based on nonlinear spectral broadening in the waveguide and subsequent spectral filtering through the ring resonator. We measure the nonlinear power transfer function for the device and find an operating peak po...

We demonstrate, experimentally and theoretically, excitable nanosecond optical pulses in optoelectronic integrated circuits operating at telecommunication wavelengths (1550 nm) comprising a nanoscale double barrier quantum well resonant tunneling diode (RTD) photo-detector driving a laser diode (LD). When perturbed either electrically or optically by an input signal above a certain threshold, t...
