![]() If, for some reason, the speed of the internet did, in fact, slow down when the splitter was installed, there are ways to get another line running to your home. If a cable splitter is installed correctly, it should not have an impact on cable modem speeds. Does splitting cable reduce internet speed? The type of coaxial cable used will determine your signal strength and how many dBm your cable can handle. Used in radio, microwave and fiber optic applications, this is the signal strength. Half the water goes one way (-3.5dB) and half goes the other (-3.5dB).Ĭoaxial cables and dBm dBm stands for the power ratio in decibels (dB) of the power measured to one milliwatt. Imagine putting a splitter in a garden hose. That’s the absolute minimum loss possible when splitting a signal. What is 3.5 dB on a splitter?ģ.5dB loss is half, 7dB is half again. If you have a 20 dBm input signal feeding a 2 way splitter the best you could have is a 17 dBm signal at each of the 2 outputs. Yes, the dB number typically refers tto the loss through the splitter. Therefore the less number outputs, the greater the signal strength. 8 How to split coax cable between ISP and receiver?Īn 8-way splitter will spilt the power so that each output usually gets 1/8 the power (12 DB) and a 5-way splitter will split the power so that each output usually get 1/5 the power (7.5 DB).7 How much signal comes out of each port on a splitter?.6 Do splitters cause signal degradation?.4 Does using a splitter slow down internet?.3 Does splitting cable reduce internet speed?.
