In the ISO/IEC 11801 generic cabling standard document, further copper cabling distinctions referred to as
“Classes” were introduced. Classes are used for classifying the permanent link or channel performance
rather than for rating the individual structured cabling components. The brief description of all classes as
specified in the ISO/IEC standard is the following:
Class A – analogue voice telephony with the bandwidth of up to 10 KHz.
Class B – frequencies up to 1 MHz for voice and slow data links (i.e. IBM 3270 terminals etc.)
Class C – this class corresponds to a permanent link or channel performance using Category 3
components. Similarly to Category 3, it covers the bandwidth of up to 16 MHz. Its primary
application today is to classify telephone distribution systems.
Class D – ratified in 1995 but updated in 2000 and 2002. Today Class D covers the bandwidth of up
to 100 MHz.
Class E – this class was finished in 2002. Class E corresponds to the permanent link or channel
performance using Category 6 components with the bandwidth of up to 200 MHz as standard
and 250 MHz as the bandwidth to which Class E/Category 6 is actually tested.
Class E
A
– a new class that is currently being defined. Class E
A
will be specified up to 500 MHz and
corresponds to permanent link or channel performance of Category 6A cabling. In particular,
Class E
A
is aimed to be used with 10GBaseT protocol.
Class F – this class covers the standard bandwidth of up to 600 MHz and the testing bandwidth of up
to 750 MHz. Class F corresponds to the permanent link or channel performance of Category 7
components.
What is Structured Cabling?
Structured cabling is a universal system
that supports digital as well as analog signal transmissions,
in which the telecommunication outlets are installed even in locations where they are not needed
at the moment of installation,
that use data cables with four twisted pairs and fiber cables,
in which long technical and also moral service life is expected,
whose correct functionality is as important for a company as the functioning of the electrical
distribution system or any other system in company’s infrastructure.
