Users have been demanding higher bandwidth since the 24x7 availability of internet connectivity has become ubiquitous. The COVID-19 pandemic situation has further spurred the demand for higher bandwidth and stable broadband connectivity to support new lifestyle norms. People are required to stay at home due to COVID-19 lockdowns, and connectivity has given them the flexibility to continue with daily activities such as work, learning and entertainment from their homes...

With the adoption of capital intensive 10-100 Gb/s transmission systems in many emerging markets such as India, the requirement of a predictable delivered OSNR in the outside plant is of paramount importance. In such economies, intense construction activity and poor installation practices lead to severe restrictions on predictable signal quality. Optical attenuation levels rise considerably beyond the beginning-of-life (BOL)/time of installation values. As a consequence of increased attenuation and the change in received OSNR (ROSNR), premature link failures especially at 100Gb/s 200Gb/s and increased costs due to cable replacement are an operational reality. Service providers in these markets are challenged in the optimal allocation and utilization of network routes...

Multiple bends in fiber contribute significantly to the increase in power loss in optical fiber cables. Bending losses are influenced by different optical parameters like Mode Field Diameter (MFD), Cut-off wavelength and MAC value. This paper highlights the results of a series of tests conducted, to determine the power loss of matched clad step index Single Mode Optical Fiber (SMF). The effect of MFD, Cut-off wavelength and MAC value have been studied with various macro and micro bend testing techniques. The testing techniques and relevant parameters, which effectively measure the bend sensitivity of SMF, have been identified...

Dynamic fatigue behavior of high strength silica optical fiber was studied as a function of relative humidity of draw environment. Fibers were drawn with graphite induction heating furnace and controlled temperature, relative humidity and particle count of the draw environment i.e. drawing furnace to coating application point. Dynamic fatigue of the drawn fibers were measured with two different modes of loading, tensile & two-point bending. Draw humidity was found to have a decided impact on dynamic fatigue measured by tensile loading...

Silica glass optical fibers have several applications such as remote sensing of mechanical distortion, thermal fluctuations, pressure variations etc. besides telecommunications. Commercially available optical fibers are usually protected with double, triple and more layers of epoxy/acrylic pol...

Acceptance sampling is one of the oldest aspects of quality assurance and is used primarily for incoming and outgoing lot-by-lot quality assurance. Sampling is generally less expensive than hundred-percent inspection and in case of destructive it is the only way. It also leads to less handling of...

Introduction Zero stress aging has been a topic of research and interest in understanding the mechanical behavior of optical fiber during the expected lifetime. Several studies have been carried out to understand the effect of aging on fiber strength properties. The aging behavior of fiber in...

One of the primary causes for the increase in attenuation in optical fiber cables is multiple bends in fiber. Hence, it becomes very critical to understand the bend sensitivity of fiber. The two predominant types of bends in optical fiber, i.e micro and macro bending, have significant impact on the r...
