Alien Crosstalk • Alien Crosstalk • Alien Crosstalk (ANEXT) is a critical and unique measurement in 10-GbE systems. Crosstalk, used in 10/100/1000BASE-T systems, measures the mixing of signals between wire pairs within a cable. Alien Crosstalk...
Fibre Distributed Data Interface (FDDI) • Fibre Distributed Data Interface (FDDI) • Fibre Distributed Data Interface (FDDI) is a networking standard developed in the early 1980s by the American National Standards Institute (ANSI) for operating...
Gigabit Ethernet • Gigabit Ethernet • As workstations and servers migrated from ordinary 10-Mbps Ethernet to 100-Mbps speeds, it became clear that even greater speeds were needed. Gigabit Ethernet was developed for an even faster Ethernet stan...
Component vs. channel testing. • Component vs. channel testing • Channel Testing • When using a Category 6 system, the full specification includes the testing of each part individually and in an end-to-end-channel. Because CAT6 is an open stan...
Ethernet Extensions • Ethernet extensions • Not a solution that you can do inmediately or for somewhat money. • Computer cables can only be too short, but never too long. The same applies to networking cables. Sometimes it is just the last met...
PoE phantom power • PoE phantom power • PoE over Gigabit Ethernet • 10BASE-T and 100BASE-TX Ethernet use only two pairs of wire in 4-pair CAT5/CAT5e/CAT6 cable, leaving the other two pairs free to transmit power for Power over Ethernet (PoE) a...
Standard and ThinNet Ethernet • Thick and ThinNet Ethernet: 10-Mbps • As a result of research done at Xerox Corporation in the early 1970s, Ethernet has evolved into the most widely implemented physical and Data link layer protocol today. Most...
