Ethernet cable that meets CAT5 (or better) standards consists of four twisted pairs of cable. With PoE you can send both data and power over the same cable to PoE-enabled devices, making it an economical solution.
There are two types of devices involved in PoE configurations: Powered Devices (PD) and Power Sourcing Equipment (PSE). PDs are pieces of equipment like surveillance cameras, sensors, wireless access points, and other devices that receive power via PoE. PSEs, which include end-span and mid-span devices, provide power to PDs over the Ethernet cable. A PoE PD access point derives its power from the PoE PSE Ethernet backhaul link.
So, what does that mean for you?
Cost and time savings, a great ROI, and more convenience.

It’s estimated that up to 20% of the cable for sale is now unsafe, unapproved, or counterfeit. Chances are that you’ve bought illegitimate cable and haven’t even realized it! Cheap cable can really hurt you (literally) in the long run. Let’s take a trip back in time to 1980. Remember the MGM Grand fire in Las Vegas
? The fire spread so rapidly that eighty-four people perished. An electrical ground fault was to blame. What if counterfeit cable causes an accident where you work?
Below we’ve listed a few pro-tips of what are the sure signs of counterfeit or cheap cable:
- Look for the UL number. If there is no UL umber, that’s an instant tip-off. Even if there is a UL number, look it up to see if it’s legit.
- Look for the ETL logo. Ask the seller for the ETL test results and check the ETL website.
- How is the printing? Is it poorly done on the box and cable?
- Check for product manuals. Legitimate products will always include brochures or manuals.
- Does the color match previous bought cable?
- Compare the weight to cable you know performs up to standard.
