This combo cable is designed to connect a digital media player with a mini AV output to an AV receiver. A right-angle mini AV plug allows easy access to jacks with minimal clearance.
Features :
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:

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.

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
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.

Combo cables are the ideal solution for all applications requiring high speed data and video, flexibility, protection from extreme environment and high and low temperature resistance. Where you need a signal with minimum distortion and attenuation or no interferences, combo cables play a pivotal part. In fact, thanks to their twin conductor construction nature, they are able to ward off many issues produced by bifilary wires.
Combo cables consist of two copper or aluminium coaxially oriented conductors surrounded by a tubular insulating layer, enclosed by a conducting shield. The quality of combo cables affects the signal interference; higher quality ensures a minimum signal interference. Moreover, also the density of the shielding affects the quality of the COAX. The result is that high quality materials and manufacturing process are essential to manufacture a reliable combo cable.
Generally, combo cables end with connectors that are usually manufactured with high conductivity metals. There are many different kinds of combo cables, which are generally defined by electrical capabilities, outer diameter or materials.
An example is represented by RG cables, where the copper and aluminium copper clad wire quality, as well as the foaming extrusion, are part of the efficiency of signal.
Although the solutions for a high quality combo cable manufacturing look like straightforward, the design of these lines requires expertise and a deep understanding of the final product.

Due to the special environment of indoor applications, indoor fiber optical cables must meet the requirements of international standards for toxicity, corrosivity and low smoke while maintaining excellent flame retardancy, mechanical properties and optical transmission characteristics. The rise of indoor fiber optical cables between floors in vertical systems, narrow space applications of communication cabinets in horizontal systems, fiber-to-desktop applications, and communication applications passing through high-pressure air-filled spaces all place different requirements on indoor fiber optical cables. How to choose the right fiber optic cable to meet the needs of different indoor applications?
At present, most indoor fiber optical cables use tight-buffered optical fibers or single-core cables as basic units, reinforced by aramid yarns, and soft optical cables with flame-retardant or non-flammable sheaths. There are also plastic optical fibers as indoor wiring fiber cables, but this product has not yet been widely used.
The tight-buffered fiber is integrated with the fiber to provide good mechanical protection, so that the fiber exhibits good compression and bending resistance when it is terminated. In addition, The tight-buffered fiber is of good flexibility and toughness,small bending radius and excellent moisture-proof function.
The good environmental protection of tight-buffered fiber can improve the service life of the fiber. The tight-buffered fiber is compatible with all standard connectors and simplifies the termination procedure and reduces the termination cost. Moreover, the tight buffer layer is easily stripped to the fiber core.
Compared with the loose tube design, the loose tube uses jelly to buffer and moisture-proof the optical fiber, while the jelly does not have fire resistance. This is far from meeting indoor fire safety requirements. Moreover, the flame spreads along the optical cable, so that the damage of the optical cable extends to the depth of the wall and deep into the pipe. During installation, a lot of cleaning materials are needed and a lot of cleaning time is spent on ointment. At the same time, a connection method is needed, which greatly increases the cost of materials. The tight-buffered optical fiber design of flame-retardant or non-flammable sheath of the indoor optical cable make the indoor optical cable fully meet the requirements of indoor safety applications.
The outer protective materials used for indoor fiber optical cables include PE, PVC, polyurethane, low-smoke halogen-free materials, flame-retardant PE, etc. indoor fiber optical cables with different outer protective materials can be used in environments with different requirements. Therefore, indoor high-performance communication transmission applications generally use indoor fiber optical cables designed with tight-buffered optical fibers.
After the indoor fiber optical cable enters the building, it is necessary to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinets on different floors, which is called “vertical wiring system”. At this time, the wiring fiber cables are mostly located in the riser in the vertical shaft between the floors. For this reason, the indoor fiber optical cable needs to withstand greater tensile force (self-weight maximum).

Most fire alarm systems fall into two categories: conventional or addressable. Conventional fire alarm systems are a simple, common, time-proven technology, which protect a large percentage of commercial buildings today. Their reliability and low cost make them ideal for small to medium size properties. Conventional fire alarm systems are characterized by a fire alarm control panel, which holds the entire system’s intelligence. Connected to this panel via hard wires are a number of detectors or initiating devices such as smoke, flame or heat detectors. Additionally, the control panel is wired to notification devices such alarm bells, strobe lights and automatic dialers.
Fire alarm cable, just like networking cables, comes in either shielded or unshielded varieties. Shielded fire wire is usually needed only for noisy EMI (ElectroMagnetic Interference) environments or for extremely long runs. One should note that excessive capacitance becomes an issue here two especially in addressable systems. In shielded fire cable, a capacitor is formed not only between the conductors, but also between each conductor and the shield. While the capacitance values are typically around 30 to 75 pF per foot for each of the two previously listed capacitors, this value adds up quickly to the low hundred μFs with cables runs in thousands of feet.
Another distinguishing detail between different fire wire is the number of conductors. Fire alarm cable is available with two to six conductors, all of which are normally rated for up to 300 VRMS. The number of conductors required is dependent upon the type of system (conventional, addressable or hybrid) and the device type.
This can be a little confusing as fire alarm cable ranges in size from 18 AWG up to 12 AWG (American Wire Gauge; the smaller the value, the larger the wire diameter). The size of the wire required for the job is dependent upon each individual detector or notification device within the circuit receiving sufficient voltage to operate. This is due to the wire itself causing a voltage drop to its own internal resistance. The larger the wire gauge, the less resistance and associated voltage drop.

With the fast development of fiber optical communication technology and the trend of FTTX, indoor fiber optical cables are more and more required to be installed between and inside buildings. Typical indoor fiber optical cable types include GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. Compared with outdoor use fiber cable, indoor fiber optical cable experience less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor fiber cables allow a small bend radius to make them be amendable to vertical installation and handle easily.
Most indoor fiber optical cables are tight buffer design, usually they consist of the following components inside the cable, the FRP which is non-metallic strengthen member, the tight buffer optical fiber, the Kevlar which is used to further strength the cable structure, making it resist high tension, and the cable outer jacket. The trend is to use LSZH or other RoHS compliant PVC materials to make the cable jacket; this will help protect the environment and the health of the end users. Usually the single mode indoor fiber optical cables are installed between the buildings where the distance is more than 100 meters, while multimode indoor fiber optical cables are used shorter distance connections. We supply SMF and MMF indoor fiber cables with various structures for different applications.
