Cat5 cat6 and cat7 with some variations.
Category 7 cable specs.
The cable standard specifies performance of up to 250 mhz compared to 100 mhz for cat 5 and cat 5e.
Most importantly cat8 ethernet patch cables can support a speed of 25 gbps or even 40 gbps.
Category 7 cable cat 7 iso iec 11801 2002 category 7 class f is a cable standard for ethernet and other interconnect technologies that can be made to be backwards compatible with traditional cat 5 and cat 6 ethernet cable.
Where other categories of cable adhere to strict specifications for all parts of their design cat7 has some unique eccentricities.
Cat 7 cable was developed with strict specifications on crosstalk and emi protection.
Commscope solutions work best when they are designed delivered configured and installed by our global partner network.
Cat 6 has to meet more stringent specifications for crosstalk and system noise than cat 5 and cat 5e.
Category 7 cat7 and category 7a cat7a are the newest cable standards for ethernet and other interconnect technologies.
To achieve this shielding was added for individual wire pairs and the cable as a whole.
Cat8 cable or category 8 cable is an ethernet cable which differs greatly from the previous cables in that it supports a frequency of up to 2 ghz 2000 mhz and is limited to a 30 meter 2 connector channel while cat8 cable requires shielded cabling as well.
Category 7 class f is backwards compatible with traditional cat6 and cat5 cable but it has far more stringent specifications for crosstalk and system noise.
Class f features even stricter specifications for crosstalk and system noise than class e.
Category 7 cat7 and category 7a cat7a s ftp is compliant to iso 11801 class fa category 7a requirements and is reach and rohs compliant.
Where cables like cat 5 cat 5e cat 6 and even cat 8 are quite typical cat7 is a little different.
Unshielded cables rely on the quality of the twists to protect from emi.
The fully shielded cable virtually eliminates crosstalk between the pairs.
Cat 7 features even more strict specifications for crosstalk and system noise than cat 6.
Category 6 cable cat 6 is a standardized twisted pair cable for ethernet and other network physical layers that is backward compatible with the category 5 5e and category 3 cable standards.
Cat is short for category and generally denotes the speed the cable is able to.
These days the choices comes down to a handful of different types.
Class f channel and category 7 cable are backward compatible with class d category 5e and class e category 6.
Cat 8 s distance limitation ensures the 40gbps speeds and related.
