Design and Usage of Fiber Optic Return Path

20 January, 2014 (09:35) | Applications & Solutions | By: fiberopticis

The CATV industry has responded to the demand of interactive, real-time, two-way television programming with return path technology. Return path management allows the viewer to send information from a transmitter located within the set-top-box (STB) located in the viewer’s home to the headend with the touch of a few buttons on the television remote. This […]

Fiber Optic Networks used in Intelligent Traffic Systems (ITS) Applications

17 January, 2014 (09:30) | Applications & Solutions | By: fiberopticis

Traffic control has been an issue since humans put the first wheels on the first cart. The modern world demands mobility. Cars represent the main method of mobility, but today’s congested highways and city streets don’t move fast, and sometimes they don’t move at all. Intelligent traffic systems (ITS), sometimes called intelligent transportation systems, apply […]

Fiber Optical Communication Networks overview

16 January, 2014 (09:04) | Applications & Solutions | By: fiberopticis

All fiber optic networks involve the same basic principle: information can be sent to, shared with, passed on, or bypassed within a number of computer stations (nodes) and a master computer (server). In addition to various topologies for networks, a number of standards and protocols have been developed, each with their own advantages, topologies, and […]

Broadband Video Fiber Optic Transmission

10 January, 2014 (04:29) | Applications & Solutions | By: fiberopticis

Broadband has become synonymous with “always on” Internet connections and digital high-definition television (HDTV). It describes the digital technologies that provide consumers with integrated access to voice, high-speed data services, video-on-demand (VOD), and interactive delivery services. This transmission concept developed slowly, and carried many of promises along the way. Today, most of these promises are […]

Baseband Video Fiber Optic Transmission Systems

8 January, 2014 (04:19) | Applications & Solutions | By: fiberopticis

Baseband Video Fiber Optic Transmission Systems consists of one video picture being sent point-to-point, such as the video output of a VCR to the video input of a monitor. Figure 1 illustrates simple point-to-point transmission. There exist two levels of service for baseband video: broadcast studio and consumer. These types describe, primarily, the quality of […]

Analog Fiber Optic Transmission VS Digital Fiber Optic Transmission

7 January, 2014 (03:33) | Applications & Solutions | By: fiberopticis

There are three predominant methods of encoding a transmission signal. Amplitude modulation(AM), and frequency modulation(FM) are both analog modulation schemes. The third method is digital modulation. The Table 1 outlines the basic characteristics of the three modulation schemes. AM, FM, and digital modulation are described in detail in other sections of this web site. One […]
