a 100 GbE MAC, denoted as 100 GE, with ten times 10G physical coding sublayer (PCS) I/O for 10-km single mode fiber.

The quickly rising tide of new bandwidth requirements driven by IP traffic, IP video, IPTV broadband and transaction-intensive Web 2.0 has caused carriers to purchase growing numbers of 10G interfaces on routers, carrier Ethernet switches and dense wavelength division multiplexing (DWDM) systems [1–3]. Equipment is now being deployed with 40G interfaces, and some long-haul DWDM-routes now carry 40G wavelengths......

A current flowing through the coil of a reader produces a magnetic field around it. This field causes a tag's coil in the vicinity to generate a small current.This mechanism is based upon Faraday's principle of magnetic induction.

A Radio Frequency Identification (RFID) system consists of readers (also called interrogators) and tags (or transponders). A typical system has a few readers, either stationary or mobile, and many tags, which are attached to objects, such as pallets, cartons, bottles, etc. A reader communicates with the tags in its wireless range and collects information about the objects to which tags are attached. Depending upon their operating principle, tags are classified into three categories: passive, se.....
