1. The cable signals entering the house are divided into multiple signals and output to the TV. The output signals are isolated from each other, and crosstalk will not occur. Each output signal compared to the input signal will have a certain attenuation, attenuation is the same.

2. The CATV splitter ports are identified as: in, out (as shown in the figure, 1in 3out means 1 into and 3 out of the CATV splitter).

3. The CATV splitter distributes the signal equally, and the signal comes out the same.

4. Mainly applied to the distribution of main lines.

1. The CATV tap takes out a small part of the signal from the main circuit and sends it to the branch port.

2. The CATV tap port is also called BR port, which means branch. If it is necessary to connect The CATV tap devices in series, it will be used. But its outlet is only one out, the rest are TAP (BR) port. The attenuation of OUT port is small, and it is the connection interface between branches. TAP port signal attenuation is large, can no longer be used as a branch series trunk connection, generally directly connected to the terminal.

3. The port identification of the CATV tap is: in, out, tap (BR) (as shown in the figure, 1in 1out 3tap is the CATV tap of three-for-one).



1. The ports of the CATV splitter are identified as: IN, OUT, OUT.This is a two-for-one CATV splitter.

2. The ports of CATV taps are identified as: IN, OUT, TAP, TAP. This is a two-for-one CATV tap.

3. The signal OUT of the CATV splitter is the same. For example, the 306 CATV splitter says that there is one inlet (IN) and three outlet (OUT). Each outlet attenuation DB number is 6DB.

4. CATV tap can be connected cascade, and the CATV splitter can not be connected cascade, because the CATV splitter cascade attenuation. After the amplifier is connected to a CATV splitter to the TV, more than two to the TV, please use a CATV tap in the middle.

5. The biggest difference between the CATV tap and the CATV splitter is that the output to the TV is different. The CATV tap output to the TV is the BR output, and the CATV splitter is the OUT output.

7. the CATV splitter for the same distribution of signals, often used in cable TV, 2 3 4 6 8 distributor or larger.

7, The CATV tap takes out a small part of the signal from the main circuit to the power level distribution device called the CATV tap.

8. The CATV tap is different. For example, the 410 branch is an inlet (IN) and there are 5 outlets, among which there is only one (OUT) port and the other 4 are BR (branch) ports. The attenuation of BR port is 10DB and the attenuation of OUT port is 2DB. In the installation, each output outlet of the CATV splitter, absolutely can not be unloaded, otherwise it will be due to impedance mismatch caused by double, generally required to add impedance matcher. And for a certain level of CATV tap branch outlet, it has little relationship.

9, CATV tap/CATV splitter difference: the level of the output and input of the CATV tap is not equal, the level of the output and input of the CATV splitter is completely equal.
