Near-End-Crosstalk (NEXT) is also a good measure of a cable quality. NEXT is the jumping of signal from one pair of conductors to an adjacent pair with a cable. A cable with a higher NEXT value than another, at a given frequency, would be a higher performing cable. [?]

10G Ethernet utilizes all four pairs for bidirectional transmit and receive each pair transmitting up to 2.5 Gbps times (x) 4 pairs to provide a total of 10G. Due to the narrow 133 millivolt signal encoding separation the application is more susceptible to electromagnetic interference (EMI) noise levels so additional TIA cable-to-cable testing was introduced to measure immunity to alien crosstalk. With the introduction of high data rate Power over Ethernet applications such as high-speed Wireless Access Points and high definition video such as HDBaseT, Category 6A is the only cable designed to transmit the combined high level of data as well as remote powering for the growing number of data-hungry and power-hungry applications.

Q: What is Catgory 6A?
Q: When should I use Catgory 6A?
1 gigabit Ethernet applications use all four pairs for bidirectional transmit and receive each pair transmitting 250 Mbps (megabits per second) times (x) 4 pairs to provide a total of 1 Gbps (gigabit per second). Due to the 0.5V signal encoding separation, the inherent noise-cancelling effect of balance twisted pair cabling works well against electrical interference found in most commercial environments. There is no cable to cable interference, also known as alien crosstalk, performance requirements for Category 6 which limits its use to 1 gigabit Ethernet and below.

Q: Why is it better using armored fiber optic cables versus running cables in innerduct?
So, interlock armored fiber optic cable (which are color coded orange, yellow and aqua) are one unit that consists of the inner fiber optic cable, the aluminum interlock armor and an outer jacket. Hitachi Indoor Armored Fiber Optic Cables The outer jacket aids in installation and also permits the printing of required information about the cable.
Interlock armored fiber optic cables are robust, have a built-in natural bend radius, and are much smaller and more cost effective than fiber/innerduct options. [?]

- Registration- any chemical substances manufactured or imported into the EU must be registered if the quantities exceed more than 1 metric ton per year. The registration requirement is per substance and per manufacturer or importer.
- Evaluation- there are two parts to the REACH evaluation process, substance evaluation and dossier evaluation. Substance evaluation consists of a selected number of chemical substances to go under further evaluation and the focus typically is on substances that are manufactured or imported in large amounts. It is also required that at least 5% of the dossiers submitted for REACH certification be thoroughly evaluated.
- Authorization- REACH authorization is mandated for some products and individuals interested in a particular product can check the candidate list and authorization list to see if the product is authorized.
- Restriction- the European Commission may select to use restriction on chemical substances in order to help control the distribution or use of dangerous chemicals within a common market. Any chemical substances under restriction can be located in the REACH Annex XVII.
