This application note will present a detailed analysis of typical 1310 nm, analog, fiber-optic networks used in CATV systems applications. In the analysis, system calculations and data will be presented that demonstrate the effects of device characteristics on system performance. The laser transmitter, fiber, and optical receiver parameters will be discussed. It will be shown how incorrect devi...

Fiber-optic DNA biosensors are a kind of analytic setups, which convert the Waston-Crick base pairs matching duplex or Hoogsteen’s triplex (T/A-T, C/G-C) formation into a readable analytical signals when functionalized singlestrands DNA (ssDNA) or double-strands DNA (dsDNA) of interest are immobilized on the surface of fiber-optic hybrids with target DNA or interacts with ligands. This review w...

performance of the fiber optic networks with different physical topologies such as point-to-point, bus, ring and star, with respect to requirements as bit rates, topology structure, bit. error rate (ber) and optical component characteristics including optical amplifiers, filters, sources and detectors, are analyzed and simulated. for this purpose, maximum number of supportable nodes and throug...

A vast majority of the installed fiber connections in the enterprise data centers consists of veryshort-reach legacy fiber cable connections, with 62.5 μm fiber core diameter. This multimode fiber, originally installed for Fiber Optic Distributed Data Interface (FDDI) applications, is capable of handling 1-2 Gb/s. It becomes a problem at 10 Gb/s, where differential mode dispersion leads into di...

In and post a fire event, an accurate and real-time evaluation and monitoring of a structure’s performance can assist firefighters for efficient survivor rescuing, which significantly improve the fire rescuing safety both for fire fighters and the trapped survivors. However, due to the lack of durable sensors, the structural performance of steel structures in fire conditions is challenging to b...

OBJECTIVE To assess the relationship between in vivo measurements of optic disc topography and histomorphometric measurements of optic nerve fiber number in glaucoma. METHODS Both eyes of 10 monkeys (Macaca fascicularis) with laser-induced glaucoma in the right eye were studied. Optic disc topography was measured in vivo with a confocal scanning laser ophthalmoscope. Histomorphometry was perf...

Artificial neural network (ANN) based prediction of the response of a microbend fiber optic sensor is presented. To the best of our knowledge no similar work has been previously reported in the literature. Parallel corrugated plates with three deformation cycles, 6 mm thickness of the spacer material and 16 mm mechanical periodicity between deformations were used in the microbend sensor. Multil...

In modern computer transmission networks the information is transferred by non-cable and cable communication channels, the latter are divided into three fundamental classes: cables on the basis of twisted pairs, coaxial cables and fiber optic communication channels. The fiber optic channels are unidirectional, therefore the full connectivity of a network can be achieved with the help of double ...
