What is difference between watt and decibel?

Decibels and watts are common terms used when describing audio equipment. In general, decibels are a measure of loudness, while watts measure amplifier power.

What is the 3dB rule?

3 dB rule: A 3 dB gain means twice (x2) the power. A 3 dB loss means half the power. For example, a system with 40 watts of input power and a 6 dB insertion loss will only have 10 watts of output power. dB: Decibel, a logarithm (equal to 10 times) ratio of the difference between two values.

What is a 0 decibel sound?

The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear. Generally speaking, the louder the sound, the higher the decibel number.

What sounds better HDMI ARC or optical?

HDMI ARC or digital optical audio? HDMI ARC is a better option. It supports Dolby Digital Plus, Dolby Atmos, and up to 7.1 channels of uncompressed audio while Digital Optical only supports Dolby Digital and up to 5.1 channels of uncompressed audio.

Which is best HDMI ARC or optical?

To begin with, HDMI ARC is the best choice if you want the absolute best audio quality possible. It supports all the latest audio formats, and lets you use the same remote for all devices. Moreover, it helps you eliminate tangled cables and clutter. On the other hand, optical cables still offer decent sound quality.

What does GPON stand for?

The most advanced technology is based on optical fibre cables and is therefore called fibre-to-the-home (FTTH). The FTTH variant more commonly used in Europe to provide FTTH services is Gigabit Passive Optical Network, or GPON.

How many times can fiber be split?

Fiber optic cabling uses light to transmit signals, and this light can be refracted and split several times over. That means, rather than 10 lines of fiber to connect 10 devices to a switch, you can run a single line of fiber and split where you need.

What is FBT splitter?

FBT (fused biconical taper) is the traditional technology in which two fibers are placed closely together, typically twisted around each other and fused together by applying heat while the assembly is being elongated and tapered. A signal source controls the desired coupling ratio.

How far can you run a fiber optic cable?

Modern fiber optic cables can carry a signal quite a distance -- perhaps 60 miles (100 km). On a long distance line, there is an equipment hut every 40 to 60 miles.

Can you fix a broken fiber optic cable?

Fiber optic cables are repaired in the same way that they are spliced. Unlike conventional copper wire, a cut fiber cable cannot simply be twisted or crimped back together. If the fiber isn't cut but damaged, then the bad section is removed and the remaining fiber must be carefully spliced.
