Q13: Why a twisted-pair cable works for 10Mbps hub but not work for 100Mbps hub?

faq_lan card
M bps runs at Cat. 5 twisted-pair cable will cause some cross-talk signal. If the 3rd and 6th wire of RJ-45 connector are not belong at the same twisted pair. That will cause problem with longer distance as above 40 meters. User should check the wiring before install the 100Mbps network. See similar questions...

Do I always need to use twisted pair cable?

RA EMC Awareness - FAQs
It’s certainly one technique in the EMC armoury. It reduces magnetic coupling to its near environment and if the circuit it carries is balanced, it also reduces the effect of capacitive coupling. Both of these effects can be helpful, and indeed essential in some applications such as unscreened data network cabling, but it is by no means a universal solution. See similar questions...

Is EURIDIS used only with twisted pair cable?

Nowadays, EURIDIS is the only international standard working with twisted pair cables for the remote reading of residential meters. The basic solution uses a field bus for communication. Nevertheless, because it may be difficult in some cases to install the two-wire EURIDIS cable, new AMR technologies have been designed over the last few years. See similar questions...

Which cable Is better, Unscreened Twisted Pair (UTP) or Screened Twisted Pair (STP)?

Manufacturers of Video Switches, Routers and Extenders.
UTP cable will give the best quality video over long distances because it has less capacitance per unit length. However, STP may be a better choice in electrically noisy environments. See similar questions...

How do I connect two 100VG Hubs together with twisted pair cable?

ProCurve Networking by HP - Support - Häufig gestellte ...
To connect 100VG hubs with twisted pair cable, you must use the uplink and downlink ports on the 100VG hubs. The hub that is connected to the server is called the "root level" hub. Hubs connected to the root level hub are called the "second tier" hubs, and hubs connected to the second tier hubs are called the "third tier" hubs, etc. To connect a root level hub to a second tier hub, you connect a cable from a downlink port on the root level hub to an uplink port on the second tier hub. See similar questions...

Can I use a twisted pair crossover cable to connect two 100VG hubs together?

ProCurve Networking by HP - Support - Häufig gestellte ...
No. Since 100VG technology uses all 8 wires "straight-through" for high speed transmission, crossover cables cannot be used. Uplink and downlink ports exist on 100VG hubs to allow the hubs to be connected using "straight-through" cables. See similar questions...

Q12: What is the twisted-pair cable for Gigabit Ethernet?

faq_gigabit
Category 5 cable is preferred to be using with twisted-pair Ethernet in structured wiring environments. This will ensure correct operation of all ports at 10Mbps, 100Mbps or 1000Mbps. Note that for Gigabit Ethernet, all 4 pairs of the twisted-pair cable are used for transmission and receiving signals. See similar questions...

Why should I use fiber optic cable in my installation instead of twisted pair?

FAQS
Fiber has several major advantages. The first is lower distance limitations. A fiber cable can be run over a longer distance without adding special equipment. Second is immunity to EMI/RFI noise. This is especially useful in factory environments where heavy machinery tends to generate high levels of EMI/RFI. The third reason is low data errors. Optical fiber tends to have a much lower bit error rate in comparison to copper cabling. See similar questions...

How do I know if a client is connected at 10Mbps or 100Mbps?

ProCurve Networking by HP - Support - Häufig gestellte ...
The port number (Link) LED will be lit when the port is connected at 10Mbps, and the rectangular LED just below the Link LED will also be lit when the port is connected at 100Mbps. See similar questions...

Why do I need a special Twisted Pair Cable for Computer Video Signal (VGA-XGA) transmission?

ALTINEX, Inc | Support
A standard CAT5 / CAT5e or CAT6 cable is made for computer network signal transmission where each twisted pair could be of different lengths. Using standard twisted pair cable could cause a color shift known as "skew." We recommend the Altinex No-skew Twisted Pair Cables, CB3150PV or CB5600PL, to minimize color shift (skew) on long cable runs. See similar questions...

What type of twisted pair cable is normally used for MultiTasker applications? CAT-5, CAT-5e, CAT-6?

What is a MultiTasker? A FAQ from Altinex
All Twisted Pair products from Altinex can either use any common CAT-5, CAT-5E or CAT6 cable. This makes the connection of AV products over an existing network easy and cost effective. Altinex twist pair products, MultiTasker based or Stand alone, have build in equalization that allows correction of a video signal for long cable runs. To ensure the best results and the longest distance possible Altinex offers no-skew twisted pair cable which does not require any equalization. See similar questions...

The port number (Link) LED will be lit when the port is connected at 10Mbps, and the rectangular LED just below the Link LED will also be lit when the port is connected at 100Mbps. See similar questions...

Why should I go from a 2Mbps line to a 10Mbps, 34Mbps or 100Mbps link?

eHampshire - Frequently Asked Questions
Mbps is very much like "dipping a toe" into broadband. A higher speed link opens the opportunity for increased numbers of computers to work on the Internet simultaneously, higher quality or more videoconferencing or perhaps using the computer network for transmitting voice calls. Some users may not be able to access ADSL services because their local telephone exchange has not yet been enabled to provide this service. See similar questions...

Can I connect the USB interface cable into a hub?

LifeScan United Kingdom -- Technical Support
Yes, the USB cable can be used with a hub, rather than connected directly into a port on the computer. See similar questions...

Can I plug the cable into a hub?

Xploder Online | PSP | FAQS | GBA Xploder SP & GBA X-Lin...
Although it should work through a hub, various factors could cause it to be unreliable. If you have any problems, try plugging it directly into a USB port on your PC. See similar questions...

Can you plug a crossover cable into a hub?

LANParty.com FAQ - Spreadin' the wealth baby!
Only if your hub doesn't do internal crossing.. most Hubs now a days do it for you already. So if you were to plug a crossover into a hub, you'd probably get bad collisions and your network just wouldn't work. See similar questions...

Will I need a cable, hub, etc?

The University of Kansas - NTS - ResNet
You will need an ethernet cable. (Scholarship Hall residents, please see the note at the top of this section). In Templin, Lewis, Hashinger, Ellsworth, McCollum, Oliver, Reiger, and Margaret Amini, there is a port for each person, so a hub/switch is not necessary. For GSP/Corbin and all other scholarship halls, there is only one port per room. If you have roommates who also would like internet access, you will need a hub/switch so that each of you can connect the ResNet network. See similar questions...
