Unshielded twisted pair (UTP) cabling is solidifying its position as the most common medium for bringing data and telephone connections to the desktop. Having taken the voice and data worlds by storm, the popularity of UTP is expanding into the world of low-quality video.
Last month we looked at the state of Gigabit Ethernet today and recognized that it will be confined to backbone networks and server connections for the reasonably foreseeable future, simply because most desktops can’t use such speed.
I guess the honest answer to the above is, “We’re working on it.” Most manufacturers have products (cable, jacks, patch cords, and test equipment) out in the marketplace promoted in one fashion or another as Category 6 compliant.
Let’s begin this series on Gigabit Ethernet by recognizing the state of local area networks (LAN) wiring today. (My Gigabit Ethernet article in the September 2000 issue of Electrical Contractor provides background.)
The realm of electrical contractors has been an ever-evolving one. Long gone are the days when installing electrical systems encompassed most of one’s time. The surge in popularity of data and voice communications created opportunities for electrical contractors.
Last month’s article dealt with testing copper cabling systems.This month, we examine the performance and testing requirements for installed optical fiber systems. Testing and performance requirements for optical fiber cabling systems were established in Annex H of TIA/EIA-568-A in 1995.
Bells and whistles don’t always sell low-voltage products. It’s the tried-and-true equipment that has become indispensable to commercial, industrial, and institutional customers. This equipment holds a market, and intercoms and paging systems are a perfect example. New they’re not.
Electronic technology is among the fastest changing industries in the world. As technology changes, more sophisticated equipment is developed. With new technology and equipment come changes in the method of connecting the equipment in both new and existing buildings.
A proposal’s primary objective is to persuade your customer to take specific action, including contracting your products and services. Often you will write a proposal in response to a request for proposal (RFP) or request for quotation (RFQ) that the prospect and/or consultant sends.
Having specialized in residential electrical wiring design and installation for many years, I felt excited about the opportunity to jump into the residential communications wiring game. This additional revenue stream could significantly increase electrical contractors’ bottom line.
Providing first-rate, after-installation voice/data/video (VDV) service to your customers can be very profitable. More importantly, providing after-installation VDV service is a must if you want your project VDV business to grow and prosper.
