Ring-type fiber optic sensor
••Demonstrate a novel passive optical-fiber sensor based on surface plasmon resonance (SPR).••••Demonstrate a novel passive optical-fiber sensor based on surface plasmon resonance (SPR).••The optical fiber sensor has a wide detection range of 1–1.4 RIU.••Comparing with the reported numerical and measurements based on an optical fiber structure, the experimental results based on fiber ring resonator present good agreement.In this paper a new passive optical fiber sensor depends on surface plasmon resonance (SPR) decorate by fabricating a configuration on metal-dielectric materials. A single-mode fiber is applied to harness the transmission light. In this work, FDTD method is introduced to control the injected refractive index on ring and fiber; hence, this leads to the shifting of the fiber SPR resonance wavelength. The advantageous of this mechanism is optical fiber sensor has a high sensitivity with the maximum of up to 1700 nm/RIU, wide detection range of 1–1.4 RIU (refractive index unit), and a nanometer resolution with a minimum of 4 nm. In addition, moreover we consider several performance parameters like sensitivity and FOM, interestingly it is shown applying silicon optical fiber improve the sensitivity. Comparing with the report. Optical fiber sensorFinite difference time domain (FDTD)More recently much efforts have done to find lable-free, cost effective, detection of multiple samples in parallel with high sensitivity method for technology of detection. Newly optical biosensors compered to another such as, mechanical, electrochemical, calorimetric, and acoustic have gained great attention owing to providing, high selectivity and sensitivity, real-time, simple, direct, and low-cost operation,,,. Generally, operation of biosensors is based on conversion of the recognition signal to the electrical signal that depends on the concentration of analyte performs. Fiber optical biosensors are divided into various groups, like: ring-core fiber (RCF), photonic crystal fiber sensor (PCF), fiber sensor based on a microwave photonic filter (MPF), fiber ring laser (FRL) and so on [3. 2.1. Optical fiber sensor structure3D view of the proposed optical fiber sensor is demonstrated in Fig. 1. The structure is periodic along X and Y directions with a pitch fixed at L = L_x = L_y = 750 nm. As it is shown in Fig. 1, the nanostructure including three layers including two metal layers silver and one silica (SiO2) layer as dielectric layer. The silver metasurface is composed of a ring-shaped hole and a vertical hollow strip inside a silver (Ag) film with thickness of h_3 = 40 nm placed on a silica layer with a thickness of h_2 = 40 nm backed with a silver ground. The ring-shaped hole serves as a bright mode with inner and outer radius of r_1 = 50 nm and r_2 = 200 nm, respectively. However, the hollow strip with a length and width of l = 600 nm and of w = 100 nm serves as a d. -
Core Layer Switch Device Debugging
The debug command displays information about the Cisco device operations, generated or received traffic, and any error messages. Could you please provide me some steps on how to enable ICMP debug on the 3850 to find the root cause of the problem? Thanks! Hello Eyad There are a couple of things that come to mind that may help you in your troubleshooting. First of all, you can check problems involved with routing (i. Note Before executing the clear macro auto configuration command, you must disable Auto SmartPorts on the switch. This command has no default setting. The debug operation takes a lot of CPU resources and should not be. The term campus LAN refers to a LAN network that spans a single geographic location, such as a building or university campus. An enterprise network is a large network that may contain several campus networks spanning different. With the Fortinet solution for integrated networking using FortiLink, the core layer always comprises a set of two to four FortiGate devices and two very high-speed FortiSwitch units, which support a large number of 100-GbE and/or 40-GbE ports with enough capacity to grow the links between them and. -

Protruding electrical box obstructing
For an electrical box that protrudes slightly, covering switches with a deep switch plate can correct the problem. The edge bevel is twice as deep as on a standard plate. Deep plates sit 5/16" off the wall. Fortunately, this issue is relatively easy to fix and any homeowner can take steps to repair a protruding electrical box. Speaking of safety hazards, it's essential that homeowners. Having an electrical box sticking out can not only be an eyesore but also pose potential safety hazards. Fortunately, with a few simple steps, you can fix the issue and restore a clean and tidy. The left side of the box is probably mounted to the stud so grab a longer drywall or deck screw, I think 3” long and go in through one of the holes in the back of the box at an angle left and drive the screw into the stud. Cause #1: Protruding Electrical Box Your. From toilet repair to a broken dishwasher, this guy covers all of the bases when it comes to home tips and in this video he shares a very important one: securing your outlets directly into your wall. -

This article covers the typical steps required to repair and/or re-terminate a damaged fiber optic cable. -
Key Considerations in Fiber Optic Communication System Design
Short summary: Designing a robust fiber optic network requires more than just choosing a cable. It includes first determining the type of communication system (s) which will be carried over the network, the geographic layout (premises, campus, outside. Introduction Getting Started Copper, Fiber or Wireless? What is “fiber optic network design?” Fiber optic network design refers to the specialized processes leading to a successful installation and operation of a fiber optic network. It also involves selecting transmission equipment. Operators define the network's topology, equipment needs, communication. Fiber optic projects are among today's most complex yet highly efficient solutions for data transmission and communication. This includes: This design process mixes engineering, geography, regulation, and economics into one deliverable: a. -
