Cat­e­gory 5e Ca­bling to Be­come Ob­so­lete for Of­fices

Asig­nif­i­cant change is on the way in how of­fice build­ings are ca­bled. Cat­e­gory 5e ca­bling, which is used in many of­fices around the world, will be con­sid­ered ob­so­lete for new in­stal­la­tions fol­low­ing a de­ci­sion in Jan­uary 2016 by the ISO/ IEC ca­bling stan­dards body.

Af­ter care­ful con­sid­er­a­tion of tech­nol­ogy trends, wired and wire­less band­width re­quire­ments and cur­rent mar­ket de­mand for the var­i­ous ca­bling types, the ISO/IEC Work­ing Group (JTC1/SC25 WG3) re­spon­si­ble for the de­vel­op­ment of the 11801 stan­dard, re­cently de­cided to upgrade the min­i­mum rec­om­men­da­tion for the hor­i­zon­tal ca­bling in of­fices.

At the re­cent work­ing group meet­ing in Mi­lan, Italy, the group agreed to raise the min­i­mum hor­i­zon­tal ca­bling re­quire­ment stated in ISO/IEC 11801-2 for of­fices (ex­pected pub­li­ca­tion on or be­fore 2017) from Class D (Cat­e­gory 5e) to Class E (Cat­e­gory 6), with a rec­om­men­da­tion for Class EA (Cat­e­gory 6A) or bet­ter ca­bling. Class D ca­bling is still the min­i­mum re­quire­ment in the drafts of 11801-3 (in­dus­trial) and 11801-4 (sin­gle-ten­ant homes), but up­grades may be con­sid­ered in the near fu­ture. In the drafts of 11801-5 (data cen­ters) and 11801-6 (dis­trib­uted ser­vices), the min­i­mum re­quire­ment is al­ready Class EA ca­bling. For new of­fice in­stal­la­tions, Class E will now be­come the min­i­mum re­quire­ment, with a rec­om­men­da­tion to spec­i­fiers and cus­tomers to de­ploy Class EA to sup­port ap­pli­ca­tions with alien crosstalk re­quire­ments, en­abling the smooth mi­gra­tion to 2.5, 5 and ul­ti­mately 10 Gb/s.

Pub­lished more than 20 years ago, the ISO/IEC 11801 stan­dard was the first in­ter­na­tional stan­dard for ca­bling in com­mer­cial build­ings and helped pave
