Black Box Explains: Networking Standards • 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 and, in 1978, the International ...

Multiplexing and demultiplexing video signals and data streams. • Multiplexing and demultiplexing • Much of the complexity in a KVM extender’s design involves multiplexing and demultiplexing the RGB (separate sync) video and various data strea...

How fibre is insulated for use in harsh environments • How fibre is insulated for use in harsh environments • Fibre optic cable not only gives you immunity to interference and greater signal security, but it’s also constructed to insulate the ...

...to terminate loose-tube cables with 6 or 12 fibres per buffer tube. Others enable you to furcate and terminate more than 200 loose-tube cable fibres, sealing the cable sheath and providing a moisture barrier at the point of termination. These kits r...

Bend radius • Bend radius • Bending a fibre cable • One of the most important considerations when installing fibre optic cable is maintaining the minimum bend radius. Bending a fibre cable excessively may cause the optical signal to refract an...

Crosstalk • Crosstalk • Near-End Crosstalk (NEXT) • One of the most important cable measurements is Near-End Crosstalk (NEXT). It’s signal interference from one pair that adversely affects another pair on the same end. Crosstalk occurs between...

...ports. Designed to consolidate the cable clutter associated with multiple peripherals and ports, USB supports all types of computer- and telephone-related devices. • USB detects and configures the new devices instantly • Before the arrival of Univ...

...connecting IEEE-488 cables, some rules apply. The total number of devices should be 15 or less. The total length of all cables should not exceed 2 metres multiplied by the number of connected devices, up to a maximum of 20 metres. And no more th...

...greater than copper cables?. Its small size makes it easier to handle, and it takes up much less space in cabling ducts. Although fibre is still more difficult to terminate than copper is, advancements in connectors are making termination easier...
