by www.fiber-mart.com A systems analysis continues to be completed to consider dynamical transient effects in the physical layer of an  Optical WDM Network . The physical layer dynamics include effects on different time scales. Dynamics from the transmission signal impulses possess a scale of picoseconds. The timing recovery loops in the receivers be employed in the nanoseconds time scale. Optical packet switching in the future networks will have microsecond time scale. Growth and development of such optical networks is yet continuing. Most of the advanced development work in optical WDM networks is presently focused on circuit switching networks, where lightpath change events (for example wavelength add/drop or cross-connect configuration changes) happen on the time scale of seconds.   It is focused on the dynamics from the average transmission power associated with the gain dynamics in Optical Line Amplifiers (OLA). These dynamics may be triggered by the circuit swit...

by www.fiber-mart.com Bend insensitive  multimode fiber  (BIMMF) has become a very active area within the telecommunication industry once it was introduced and popularized. It typically signifies technical advancements in the production of multimode optical fiber for easier installation, and cable management for multimode fiber cables through improvements in bend insensitivity. This article will focus on some useful information about BIMMF from the perspective of its working principle, performance in networking and unique advantages as well.   What Is Bend Insensitivity? An optical fiber consists of a core and a cladding. Although both of these regions are made from glass in telecommunications grade fibers, they are significantly different from each other. Each region is designed to capture light within the core and transmit it to the opposite end of the fiber. During this process, the light may follow many paths, depending on the angle at which the light hits the...
