Ethernet Cable Write For Us

Ethernet cable (1)

Here you try to connect an ethernet cable to your favorite device. One small problem: you have no idea what kind of network ethernet cable it is and if it works. What kind of cable is it? Does size really matter?

The answers are printed on the cable jacket. This is also known as the “ledger.” Here’s a great example of what you’re looking for: For Submitting Your Articles, you can email us at contact@supercomputerworld.com

Direct Translation Of What Is Above:

Manufacturer (in this example, trueCABLE)
UL jacket fire rating (CMR or riser rating in this example)
Maximum operating temperature in Celsius (75 degrees C for this cable)
Number of warped pairs in the cable (4 teams, i.e., a total of 8 conductors)
Type of shielding (if any): unshielded in this case, i.e., U/UTP (UTP generic)
Wire Gauge (specified as 24AWG in American Wire Standard). The higher the number, the solvent the copper electrode.
Certifications. In this example, ETL has a cETLus approval mark and has been verified by Electrical Test Laboratories (ETL). The cETLus mark certifies that a product meets North American electrical and security standards, including those written by Supporters Laboratories (UL) and the Canadian Standards Association (CSA). In addition, this mark means UL is listed for performance.
Category cable type, in this example, Enhanced Category 5 or Cat5e
Cable bandwidth in MHz, in this example 350 MHz
ANSI/TIA standard with which the Ethernet cable was built, in this case 568-C.2
RoHS. It means the restricted and lead-free use of other hazardous materials used in the design and manufacture of the product.
XXXXFT indicates which footmark you are on and is useful when routing and measuring cable for installation
MM/YY indicates month and year of making, sample would be 01/19 for January 2019

So, Colloquially, Here’s What You Really Need To Know:

The cable is certified as electrically safe and fire resistant when installed according to the CMR classification (inside walls, indoors only).
The cable is a Cat5e cable, which means it supports 10/100/1000 Mbps up to 328 feet or 100 meters
Wire gauge is 24 AWG (without insulation around individual conductors)
You can use it in an environment up to 75 degrees Celsius or 167 degrees Fahrenheit
The cable is unshielded or commonly referred to as UTP. Technically it’s U/UTP if you want to fancy the whole thing…

So there you have it! Not too hard. Is there a standard way to print these things onto the wires? Not exactly. Most manufacturers will follow the example above, but remember that every cable is different and each manufacturer has creative license to label it as they see fit. Meaningful how to read the ledger and sometimes between the lines will give you an edge!
