...in 4-pair CAT5/CAT5e/CAT6 cable, leaving the other two pairs free to transmit power for Power over Ethernet (PoE) applications. However, Gigabit Ethernet or 1000BASE-T uses all four pairs of wires, leaving no pairs free for power. So how can PoE ...

...video over CATx cable at distances greater than 30 metres. • As cable length increases, picture quality decreases. Smearing is caused by the cable attenuating high-frequency signals. The image is also dimmer because of the cable’s resistance...

Crossover Cable • Crossover Cable • Crossover cable is generally used for hub-to-hub connections. The send and receive pairs are crossed between Connector A to Connector B on either end of the cable. There are two standards for the pairing of ...

...Explains: Fibre Optic Cable • Fibre optic cable is one of the fastest growing transmissions mediums for both new cabling installations and upgrades, including backbone, horizontal and even desktop applications. • The Black Box explain series make ...

...Possible causes: • Bad cable or cable that’s too long, causing either the video signals or EDID/HDCP control signals not to be transmitted properly. Make sure that you use quality, high-speed HDMI® cables—they don’t even have to be expensive ones—o...

LSZH and PVC cables • LSZH and PVC cables • The European market is demanding that cables used in LANs, WANs, etc. meet LSZH specification. The IEC 60332-1 governs the Flame Retardant Grade specifications in reference to LSZH cables. • Reductio...

Cable-Based A/V Distribution • Cable-Based A/V Distribution • In-line based • In-line extenders, installed at some point within a link, extend signals over their native cabling with no signal conversion occurring. These amplification or repeat...

...Gigabit over Category 5 cable has been approved, enabling short stretches of Gigabit speed over existing copper cable. Today, you have many choices when implementing Gigabit Ethernet: • 1000BASE-X • 1000BASE-X refers collectively to the IEEE802.3z s...

50-µm fibre optic cable • Fibre optic cable. • The background • As today’s networks expand, the demand for more bandwidth and greater distances increases. Gigabit Ethernet and the emerging 10-Gigabit Ethernet are becoming the applications of c...

...fibre optic cable • Loose-tube vs. tight-buffered fibre optic cable • There are two styles of fibre optic cable construction: loose tube and tight buffered. Both contain some type of strengthening member, such as aramid yarn, stainless s...
