How to Choose Right UTP CAT5e Cable for Your Network?

Leave a comment

UTP CAT5e Cable (Cat 5 enhanced), also know as Cat5e, is currently the most commonly used Ethernet cable in new installations. It’s designed to greatly reduce crosstalk, which means the UTP CAT5e is better at keeping signals on different circuits or channels from interfering with each other. A step above Cat 5, it can handle 1000 Mbps speeds (gigabit Ethernet) at 100 MHz wit a maximum cable length of 328 feet (100 meters). How to choose right Category 5e Cable for your network? This article may give you the answer.

Straight-Through or Crossover Category 5e Cable?

RJ-45 conductor UTP CAT5e cable contains 4 pairs of wires each consists of a solid colored wire and a strip of the same color. There are two wiring standards for RJ-45 wiring: T-568A and T-568B. The two wiring standards are used to create a cross-over cable (T-568A on one end, and T-568B on the other end), or a straight-through cable (T-568B or T-568A on both ends). To create a straight-through Cat 5e, you’ll have to use either T- 568A or T-568B on both ends of the cable. To create a cross-over UTP CAT5e cable, you’ll wire T-568A on one end and T- 568B on the other end of the cable.

The straight-through UTP CAT5e cables are used when connecting Data Terminating Equipment (DTE) to Data Communications Equipment (DCE), such as computers and routers to modems (gateways) or hubs (Ethernet Switches). The crossover UTP CAT5e cables are used when connecting DTE to DTE, or DCE to DCE equipment, such as computer to computer, computer to router or gateway to hub connections. The DTE equipment terminates the signal, while DCE equipment do not.

Basic Connections: Speaker Cables

Leave a comment

Speaker cables connect the outputs of the power amplifier or the amplifier section of the receiver to the speaker. These cables carry the high-powered electrical currents required to move the internal components of the speaker (the magnets that move the drivers).

You need one pair of speaker cables for each speaker in your home theater (except the subwoofer, if it’s an active system that uses an analog audio interconnect cable). Some expensive speaker systems can use two pairs of speaker wires per speaker. These systems are either biwired or biamped:

  • Biwired: Two sets of speaker wire connect to the same output on the receiver or power amplifier, and you plug them into two sets of terminals on the speaker itself. In most cases, this setup is not worth the expense of the extra set of speaker cables.
  • Biamped: The speaker uses two separate amplifiers — one for the low-frequency drivers and one for the high-frequency drivers.

How to Choose The Coaxial Cable

Leave a comment

Everyone knows what a coaxial cable is, right? It’s that fat wire that goes into your cable box, satellite receiver, or into your TV from an antenna. It looks different from an audio cable or headphone cable largely because of its heft.

There’s a little more to a coaxial cable than that. A coaxial cable carries its voltage on the inside “core” wire, and is surrounded by layers of shielding that stop any signal leakage. The first layer, the dielectric, provides distance between the core and the outer layers, as well as some insulation. The next layers, collectively called the shield, keep electrical impulses and radio transmissions out and keep any stray impulses in. Finally, a jacket made of flexible plastic or rubber protects the entire cable. Keeping the entire cable the same size, and keeping out stray signals, are important.

Another important characteristic is that in a coaxial cable, unlike a headphone or audio cable, the core is used as part of the connector. So, it makes a direct connection. This helps keep the signal as strong as possible.

Coaxial cable is perfect for broadcast television and satellite signals, which carry a huge amount of information and are very sensitive to outside interference. A satellite signal cable must carry signals from 2MHz to 3,000MHz. Compare that with an audio cable which just needs to carry signals up to 2 MHz. That’s a massive amount of information.

Generally, coax cables will be referred to by a code such as RG6/U. RG is a very old specification that refers to the “Radio Guide,” a military guidebook. Any cable marked “/U” is designed for universal use, as opposed to those cables specifically used for computer data or other specified uses. If your cable is not marked “/U” that’s ok as well.

Advantages of Fiber Optical Cables

Leave a comment

A fiber optical cable is used to transmit data through fibers (threads) or plastic (glass). During this pack of glass which are within sorts of threads transmit modulated message along sunshine wave. There are many advantages by using these cables over other kinds of communication cables like bandwidth of these cables is high, less vulnerable than metal cables to interference, less thin, lighter, and thus info are often transmitted within type of digitally.

Most disadvantages of those cables are installation is dear, more delicate and difficult to repair together. A fiber optical cable is formed by drawing glass or special sort of plastic, which can transmit light from one end of fiber to a special end. glass fiber cables use light signals to transmit data signals instead of traditional electrical signals. Twisted pair cables use current to transfer data signals.

Generally, there are three sorts of fiber optical cables: 2 glass glass fiber —single mode fiber optical cable and multimode optical fiber, also as plastic glass fiber (POF).

The advantages of optical cable include the following

  • Bandwidth is above copper cables
  • Less power loss and allows data transmission for extended distances
  • Optical cable is resistance for electromagnetic interference
  • Fiber cable is sized as 4.5 times which is best than copper wires
  • As cable are lighter, thinner, in order that they use less area as compared to copper wires
  • Installation is extremely easy thanks to less weight.
  • Optical fiber cable is extremely hard to tap because they don’t produce electromagnetic energy. These optical fiber cables are very secure for transmitting data.
  • This cable opposes most acidic elements that hit copper wired also are flexible in nature.
  • Optical fiber cable are often made cheaper than equivalent lengths of copper wire.
  • Light has fastest speed within universe, such a lot faster signals
  • Fiber optical cables allow much more cable than copper twisted pair cables.
  • Fiber optical cables have how more bandwidth than copper twisted pair cables.

5 Types of Fire Alarm Cable

Leave a comment

1. What Is FPLR Cable?

Fire power limited riser (FPLR) cable is the cheapest of the bunch because it’s the most basic. When you don’t need a shield or plenum insulation, you go with a riser fire alarm cable that gets installed vertically, hence the name “riser.” These cables come in sizes 22 AWG through 12 AWG with two, four, six or eight possible conductors.

FRLR riser cables, including the shielded variety, must pass UL 1424 and UL 1666 tests for resistance to fire spread.

2. What Is FPLR Shielded Cable?

FPLR shielded fire alarm cables include an aluminum polyester foil shield over the conductors to protect against electromagnetic interference (EMI). A foil shield is the only type of shield offered in standard riser alarm cables. A drain wire is also used within these shielded cables to provide sufficient grounding and avoid interference. This additional EMI protection will cost a little more than its unshielded counterpart. If you need a braid shield or foil/braid shield, you will need to wait about 4 to 6 weeks and purchase about 20,000 feet.

3. What Is FPLP Cable?

Fire power limited plenum (FPLP) fire alarm cables are plenum rated for horizontal overhead installations. Plenum cables can be installed in the plenum, which is where the name came from. You’ll notice that plenum cables are much more expensive than riser cables because of the additional engineering and protection they offer. The plenum jacket is made from low-smoke plastics like PVC and limits fire spread throughout the ducting system. They’re both offered in similar sizes because the amount of copper, or current, doesn’t change when the insulation changes.

FPLP and its shielded variation must pass UL 1244 and 1666 tests.

4. What Is FPLP Shielded Cable?

FPLP shielded fire alarm cables also include an aluminum polyester foil shield over the conductors to block electromagnetic interference. Sometimes there are a few cables running next to each other in the plenum and need shielding to block interference between one another. However, if the cable is installed by itself, it shouldn’t need a shield.

5. What Is FPL Cable?

Fire power limited (FPL) cable is non-plenum rated and boasts less protection against fire. FPL cables are not suitable for installation in environmental air spaces like plenums, risers or ducts unless installed in a conduit.
