Last month, we mentioned centralized fiber local area networks (LANs) as a place where fiber optics are more cost effective than copper wiring. What exactly is a centralized fiber network and how is one designed and built?
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.
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.
With the approval and publication of Telecommunications Industry Association (TIA)-TSB67 “Transmission Performance Specifications for Field Testing of Unshielded Twisted-Pair Cabling Systems” in October 1995, TIA launched the industry requirement for cabling system transmission performance and field
Copper technology has evolved to the point where a 100-meter maximum distance is among the golden rules of premises cabling. This rule is rooted in 10BASE-T Ethernet and the first edition of Telecommunications Industry Association/Electronic Industry Association (TIA/EIA)-568 in 1991.
This column’s title is probably the most commonly used phrase in Requests for Quote or Bid. Therefore, it is appropriate to understand what, “The cabling system shall be in accordance with TIA/EIA-568-B.1” means and does not mean relative to the bidding process.
The expansion of high-speed copper data cabling options—from Category 5 into Enhanced Category 5e, Category 6, and a multitude of proprietary classification schemes—has left customers and contractors confused about what they need, and even about what they’ve got once they’ve bought it.
