Shielded Ethernet Cables • Shielded Ethernet Cables • STP and S/STP • Two basic types of shielded cables are offered by Black Box and the Industry.The first group are cables with an overall shield know generically as STP. The second are constr...

Cable construction and delay skew. • Cat5 extender and CAT5e or CAT6 cables (delay skew) • If you connect CAT5e or CAT6 cable to a CAT5 extender, the result is blurry images on your monitor. The effect is known as delay skew, but do you know w...

...twisted-pair (STP) cable using either a DB9 connector or a unique square connector called the IBM data connector. Later, Token Ring was adapted to use conventional unshielded twisted-pair (UTP) cable with RJ-45 connectors. The most common kinds...

SFP, SFP+, and XFP transceivers • SFP, SFP+, and XFP transceivers • SFP, SFP+, and XFP are all terms for a type of transceiver that plugs into a special port on a switch or other network device to convert the port to a copper or fiber interfac...

...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...

...money. • Computer cables can only be too short, but never too long. The same applies to networking cables. Sometimes it is just the last meter that is missing, but in many cases some kilometres are missing. A standard 10/100 or 10/100/1000 Cop...

...ratios • Within a CATx cable of a certain length, the individual pairs might have individual different lengths, caused by higher or lower twist ratios. • There are two common cable standards: • One with a 2 + 2 structure (two pairs of approximately...
