What is the minimum cable type 100base TX specifies?
Type 1A STP or Cat 5 UTP.
What does an rs-232 cable look like?
It looks like any other low voltage cable, such as a CAT-5 Internet cable. There are several variants to the RS-232 standard. The standard defines a 25 pin configuration for serial data communications. In many cases fewer conductors are used. Google RS-232 standard for definition of the connectors, cable length, restrictions, baud rates and voltage levels.
What is formula for calculate size of cable?
CABLE and WIRE are not the same thing.Cables are sized by the diameter of the longest side (romex isn't round, it's an oval, compared to CAT 5, which is round)Wires are sized based on the type of insulation and gauge of copper.Then you take that info to the code book. A chart tells you the answer. BEWARE: multiple cables or wires in a conduit changes the equation.Whether or not more will fit, the only correct way to size cables or wires is to use the Code Book.For UK InstallationsThis topic is covered in Appendix 5 of the On-Site Guide supplement to BS 7671:2008 Requirements for Electrical Installations (the 'IEE Wiring Regulations'), although this Appendix only relates to the ease with which cables can be drawn in, and does not take into account the effect of 'grouping' (i.e. the effect that the temperature of each conductor will have on the rest). The number of cables permitted depends upon (1) the total cross-sectional area of all the cables drawn in, (2) the length of run, and (3) the presence of bends.The effect of 'grouping' is to reduce the number of cables actually allowed within a conduit (or other enclosure), because, as the number of circuits increases, the current-carrying capacity of the cables reduces. Guidance on this is provided through 'space factor', which is the ratio of the (total csa of all the cables) to (the internal csa of the conduit), expressed as a percentage, with the maximum permissible space factor being 40%. The remaining 60% space is required to allow the dissipation of heat from the cables. (As the first answer indicates, the csa of a flat cable is based on the maximum width of that cable).
What does equals equals mean in java?
operator to compare two objects. The simple "=" sign is used for assignment - assigning a value to a variable. Here are examples of the two: x = 15; // Assign the value 15 to the variable if (x == 10) ... // Compare variable "x" with some value
What is a fairy loop for?
whos the cat in the hat who played cat in the hat
What does the twisting of the wires do in a CAT 5 cable?
limits signal degradation
What does the twisting of the wires achieve in a CAT-5 cable?
It reduces the opportunity for the signals on one pair to be transferred accidentally to a different pair.
How many wires does a CAT-5 cable have a CAT-53 and a coaxial cable?
Cat-5 has 4 pairs and 8 wires
How many wires does a CAT-5 cable a CAT-53 and a coaxial cable have?
Cat-5 has 4 pairs and 8 wires
The Common type of network cable that has 8 wires?
Cat 5, Cat 5e
How may pair used in cat 5 cable?
4 pairs of wires, or 8 wires total
How many conductors are in a CAT-5E cable?
An RJ45 connector has 8 conductors. it has the naming convention of 8P8C (8positions 8conductors).
How to wire a Cat 5 cable for network connectivity?
To wire a Cat 5 cable for network connectivity, follow these steps: Strip the outer insulation of the cable to expose the inner wires. Untwist the pairs of wires and arrange them according to the T568A or T568B wiring standard. Trim the wires to the appropriate length and insert them into the RJ45 connector. Crimp the connector onto the wires using a crimping tool. Test the cable to ensure it is properly wired and functioning.
Why are there 8 wires in an Ethernet cable?
In Cat 5 cable based on fast ethernet (100 mbsp) 4 are used to Send and Receive. The other 4 wires are unused. All 8 wires are used for gigabit communications.
Why are the wires twisted in twisted pair cabling?
In multi pair cable sets, for example a Cat. 5 cable, the wires of each pair are twisted to prevent mutual induction into the other cable pairs. The tighter the twist, the less amount of induction into the other cable pairs.
How many wires of cable cat 6 is use for data?
just one optic cable can carry a lot information to computers
How do you Enable Ethernet and telephone to be transmitted over the same Cat 5 cable?
Ethernet network traffic on a cat 5 cable only uses 4 wires of the 8 in the cable. Telephone voice transmission only uses 2 wires. Therefore, you can take any 2 of the unused network wires (pins 4 or 5, 7 or 8) and use it for voice. You would then have both data and voice transmission in the same cable.
