6 Ft Coax Cable
Since it produces a large reflection, it is simply located at about 17.2 m from the CableIQ. Interpreting the data within the COAX Trace allows necessary conclusions to be drawn. This is and indication the splitter is of excellent quality since there isn't a reflection for the splitter itself.
This is the cue to the consumer that the Coax TDR hint must be seen for further information. Consider the next example of coax cabling which has a 2 method splitter being examined by a CableIQ (Figure 2).
If your Cable Internet started misbehaving unexpectedly do that before you pay for a service name. Check with your cable service provider to ensure that your cable information service is out there and working. This COAX Trace shows there's a massive negative impedance change on the level of the splitter. This indicates the splitter is not a good impedance match.
It has three branches of lengths L1, L2 and L3 respectively. L2 and L3 are linked to the output ports of the splitter and are un-terminated. Yes, the CableIQ can detect the presences of splitters in a coax system, however not all the time present their location (output branches have to be un-terminated). In the previous, detecting the presence of splitters, their high quality and the variety of splits has been very difficult to do without specialised test tools.
However, the technology implemented in the CableIQ now allows this info to easily be decided. The CableIQ operating in Coax Discover Mode can detect the presence of a splitter in a coax run and alert the user. Once a splitter has been detected, the person can examine the COAX TDR Trace to take a look at the reflections on the coax run and determine different info. The TDR trace will contain info to typically assess the quality of the splitter and how many instances it's break up.
It is commonly very useful to know whether or not there are splitters in a coax distribution system and to have the ability to assess the splitter quality. Its additionally helpful to determine how many instances the sign is split on a selected run. Some installation practices solely enable at most a 2 way split, so figuring out if there are multiple splitters is essential.
There are three reflections after the splitter, not two as in the case of the great splitter. The first two reflections characterize the ends of respective branches. The final one is due to some multi-reflection within the system caused by the poor impedance match of the output ports.
The two reflections indicate that there's solely a 2 means break up. Note in the case of a great splitter the CableIQ may not be capable of locate it since there isn't any reflection off an excellent splitters, however it could detect there's a splitter within the cabling. However, sometimes even in the case of a great splitter there could also be a slight reflection that allows the consumer to determine the location of the splitter. When testing in Coax Discover Mode, the CableIQ can detect the presence of the splitter. Figure 3 shows the display with the Splitter or Fault warning that might be present if the CableIQ suspects a splitter is within the cabling underneath take a look at.
