By John schmidt The problem with having choices is that in the distances such as: end, you must make one. This is clearly apparent » Campus backbone cabling with structured cabling where the primary protocol, » Building backbone cabling Ethernet, is supported by a variety of media types, » Horizontal or centralized cabling for distances greater including singlemode and multimode fiber, different than 100 meters, such as a factory environment or categories of shielded and unshielded twisted pair copper, large data center and wireless. Regardless of what you may hear in the marketplace, each media has an inherent set of strengths The disadvantage of optical fiber is the cost of active and weaknesses. The choice you make as a network electronics such as switch ports and network interface designer should to be made based upon what is right for cards (NIC). It is estimated that the cost of 10GBASE-T the unique requirements of the network. copper electronics will be roughly half the cost of 10 This article explores the advantages and disadvantages gigabit optical fiber equivalents initially and will continue of the common media types that are used today to to drop as volume and technology progress. transmit Ethernet with a focus in on higher speeds such as gigabit Ethernet and 10 gigabit Ethernet because these are, Optical Fiber Advantages for the most part, new to many network designs. » Distance » Size of media, relative to copper .
