Fiber Optics

Alcatel-Lucent (Euronext Paris and NYSE: ALU) says it is deploying an open access GPON fiber-to-the-home (FTTH) network for the delivery of triple-play services (TV, telephony, and high-speed Internet) at bandwidths of up to 100 Mbps in Sasbachwalden, Germany. In total, the GPON FTTH network will serve 1,555 households in 648 separate buildings in 44 different streets.
The community itself initiated and realized the GPON FTTH project — from the initial idea to the selection of Alcatel-Lucent as a technology partner — together with a planning office and in close coordination with Neue Medien im Ländlichen Raum, a state clearinghouse that advises rural communities in Baden-Württemberg on broadband access.
“This optical fiber project is an important step in readying our community — and the vacation region as a whole — for the future, fulfilling a long-held dream,” said Valentin Doll, mayor of Sasbachwalden. “We recently lost a number of businesses due t[......]

Efforts by the European Commission (EC) to put in place a new telecommunications framework that focuses on broadband fiber access technologies have raised optimism at the FTTH Council Europe, whose members say clear, coherent regulation is needed to spur massive FTTH deployments.
After some false starts, the European Commission is on the way to bringing a degree of pan–European regulatory certainty that should spur FTTH deployments. But obstacles remain.
“This is a major step,” said Joeri M. Van Bogaert, president of the FTTH Council Europe. “A major change is that FTTH and FTTC have been separated and a graduated set of remedies have been made.”
Today, European Union (EU) regulations cover traditional copper telecom networks and do not address issues arising from fiber–based next–generation access (NGA) networks. The opening of telecom networks, different market conditions, and the advent of a variety of FTTx technologies have created a very diverse regulatory picture in [......]

Fiber Optic Transmission System Helps Protect Wonders of the Ancient World in Egypt
Fiber Optic Transmission solutions from VOSCOM are protecting some of the greatest monuments of the ancient world at the Giza Plateau on the Nile River, near Cairo, Egypt. Fiber Optic Transmission Systems from VOSCOM enable  signal transmission from more than 100 video cameras in a surveillance system that watches the perimeter of the Pyramids of Giza, the Sphinx and other archaeological treasures.
Recently, the Egyptian government determined a need to increase the level of protection of the celebrated historical sites by installing a video surveillance system around the entire perimeter of the Giza Plateau. The goal was to create a system able to view any area of the plateau complex from a single control room facility. Egyptian government engineers evaluated system requirements for several months before choosing VOSCOM to provide signal transmission from cameras located around the Giza site. VOSCOM fib[......]

SINGAPORE — CommunicAsia 2010 — When the CEO of an operator that’s already offering a 100-Mbit/s fixed broadband service questions the need for such a level of personal bandwidth, then it’s time to take a closer look at consumer demand for super-fast connections.
Never one to shy away from the real-world issues affecting service providers, Neil Montefiore, CEO of Singapore’s StarHub Pte. Ltd. and a veteran of the Southeast Asia communications industry, noted during a CEO panel here that “no one is quite sure what people will do with 100-Mbit/s symmetrical,” asking: “Do people really need that speed?”
Montefiore was referring to the high-speed service that will be on offer to all of Singapore’s residents over the island state’s open National Broadband Network (NBN), which will offer 100 Mbit/s to every household over GPON connections within a few years. Those connections can be used by any retail service provi[......]

PMC-Sierra Inc. announced the first pluggable GPON optical network terminal (ONT) reference design that can connect any customer premises equipment (CPE) equipped with a standard small form-factor pluggable (SFP) port to a high-speed passive optical network (PON), according to a company spokesperson.
The low-power, plug-and-play ONT enables carriers and system vendors to upgrade existing service-oriented home and small/medium business equipment, including gateways, routers, and integrated access devices, to full GPON functionality without hardware or software redesign. It eliminates the need for carriers and service providers to deploy new CPE when introducing advanced fiber-based services.
The pluggable ONT, based on PMC-Sierra’s GPON SoC for mini-ONT applications, is powered by standard interfaces in the host device and does not require a dedicated power supply.
“FTTH networks have passed the initial adoption stage and service providers are looking for innovative ways to c[......]

The only goal of the fiber optic link in a fiber optic transmission system is CCTV Transmission of electrical signals at a distance between any two points A and B, without Reducing the quality of the transmitted signal. In this way, the fiber connection transparent to the user. A similar situation is with a phone call where you want be able to another person, anywhere, they speak as if standing next to you.
The basic elements of a system for transmitting CCTV fiber optic as follows:
• Electronics optic converter (transmitter) at the end of the camera connection.
This camera takes the analog signal of 1 V peak to peak of the surveillance camera and transforms into a light that varies in proportion to the camera output Signal. The signal of the light generated by an LED (Light Emitting Diode) or laser Transmitter, which is designed to couple a maximum of light produced in a fiber.
• fiber light transmission and optical fiber cable.
The optical fiber guides light from the[......]

The principle reasons for using optical fibre as the transmission media in CCTV applications are:
·  The maintenance of picture quality and control data integrity over extended distances:
This is the main reason for the use of fiber optic signal strength than loss characteristics of copper cable. In general, the attenuation of coaxial cable to a the signal frequency of 5 MHz, 20 dB / km. In mitigation of fiber comparison is 0.3 to 3 dB / km mean that the fiber optic transmission distances of 60 km and can achieved, depending on exact details of the application. In addition to this low signal loss on fiber frequency range of the signal very large, so that made optical fiber can be used for transmission of multiple video signals over long Distances.
·  Immunity to electromagnetic interference:
Optical fiber transmits signals as light pulses instead of electrical impulses. This light transmission is not the existence of electromagnetic fields. As fiber transmission can lead to[......]

The use of fiber optic transmission is now commonplace in telecommunications, data Communication and dissemination of quality applications of TV signal. However, the use of  Fiber as a transmission medium in security and CCTV surveillance applications is a  relatively new development in the 1990s fueled by the need to install extensive CCTV systems to fight against crime, vandalism and terrorism. Classically  Cameras, monitors on copper-wire connections with the lowest cost components  provision. increased in size with the system provider, the distance between cameras and monitors, In addition, increases in an unacceptable degradation of the quality of the video signal received. ie  get the picture quality, for bond distances of 100-150 m. This has led to the use of  Fiber Optic Transmission should be considered advantageous in that consciousness  Applications.
In these sections, we will demystify transmission fibers used for the trial CCTV To use the system. We will be des[......]

CCTV and surveillance technology is constantly evolving and today’s digital IP cameras provide increasingly sophisticated capabilities for monitoring, recording and reviewing activity inside and outside your property. With a wide choice of products available, understanding your options can be confusing, whether you’re new to CCTV or planning to upgrade an existing system. Here are the top ten things you need to ask yourself to get the right CCTV system for your needs.
1: Defining criteria
Why do I want to install CCTV?
It’s essential to start with a clear idea of what you want your CCTV system to achieve. What suits your neighbour or another business may not suit you. Are you considering the investment as a deterrent to intruders and thieves? To record access to a building or car park? To monitor movement in particular areas of your property? To record activity round the clock or at specific times, for example when your property is unoccupied? You also need to think about what you want[......]
