Kev Faib Tawm Ethernet Cable Jacket: CMR vs. CMP vs. CM vs. CMX - Nkag Siab Txog Kev Ruaj Ntseg thiab Kev Ua Haujlwm Code

Classification ntawm coverage cable ethernetCMR vs. CMP vs. CM vs. CMX - Nkag siab txog cov cai kev ruaj ntseg thiab kev ua tau zoo
Kev xaiv txoj hlua Ethernet zoo tsis yog hais txog qhov ceev xwb (Cat5e, miv6thiab lwm yam). Kev faib tawm ntawm lub tsho cable (CMR, CMP, CM, CMX) yog qhov tseem ceeb rau kev nyab xeeb, kev ua raws li txoj cai, thiab kev teeb tsa kom raug. Kev faib tawm no qhia txog qhov hluav taws kub ntawm lub cable thiab nws qhov haum rau ntau qhov chaw hauv tsev, raws li tau teev tseg los ntawm Tebchaws Meskas cov cai hluav taws xob (NEC). Kev siv hom tsis raug tuaj yeem tsim kev phom sij hluav taws thiab ua txhaum cov cai.

Nov yog cov lus qhia ceev ceev rau kev faib tawm ntawm Ethernet cable jacket:

CMP (Plenum Class): Kev faib tawm kev nyab xeeb hluav taws siab tshaj plaws. Tsim los siv rau hauv qhov chaw plenum (cheeb tsam tswj huab cua saum qab nthab dai lossis hauv qab pem teb siab). Cov xov hlau CMP tsim cov pa luam yeeb tsawg kawg nkaus thiab txo cov nplaim taws kis mus rau lwm qhov thaum muaj hluav taws kub. Yuav tsum muaj rau cov chaw plenum. Lawv kim tshaj plaws.

CMR (Chav Riser): Rau kev khiav ntsug ntawm cov plag tsev (risers), xws li cov ncej elevator lossis cov ducts txuas cov theem sib txawv ntawm cov tsev. Cov xov hlau CMR tiv taus qhov kis ntawm cov nplaim taws. Kev tiv taus hluav taws ntau dua li CM/CMX. Yuav tsum muaj rau cov ntawv thov riser.

CM (Lub Hom Phiaj Dav Dav): Haum rau kev txuas kab rov tav dav dav hauv ib lub plag tsev, tsis yog hauv plenums lossis risers. Feem ntau siv rau hauv chaw ua haujlwm, tom qab phab ntsa, thiab hauv qab nthab tsis muaj plenums. Muaj kev tiv thaiv hluav taws yooj yim. Nws yog cov cable feem ntau thiab pheej yig tshaj plaws rau kev siv hauv chaw ua haujlwm.

CMX (Sab Nraum Zoov/Siv Tsawg): Feem ntau yog siv rau sab nraum zoov, nyob hauv tsev, lossis siv tsawg hauv tsev (xws li tsev neeg ib leeg, hauv qab ntaub pua plag, thiab kev teeb tsa).VIM LI CAS(rales). Nws muaj qhov tiv taus hluav taws yooj yim tshaj plaws. Nws tsis raug tso cai rau hauv qhov chaw plenum, cov kav dej ntsug, lossis cov kab rov tav lag luam uas xav tau CM lossis siab dua. Nws yog qhov pheej yig tshaj plaws.

Vim li cas qhov kev qeb duas thiaj tseem ceeb?

Kev Nyab Xeeb Hluav Taws: Tiv thaiv lossis qeeb qhov kev kis ntawm cov nplaim taws thiab txo cov pa luam yeeb lom hauv cov chaw tseem ceeb.

Kev ua raws li cov cai ntawm lub tsev: Kev siv cov xov hlau tsis raug yuav ua rau tsis tuaj yeem kuaj xyuas thiab ua rau muaj kev kho kim heev.

Kev Pov Hwm thiab Kev Lav Ris: Cov chaw uas tsis ua raws li cov cai yuav ua rau kev pov hwm tsis muaj txiaj ntsig lossis tsim teeb meem kev lav ris.

Xaiv kom zoo zoo:

Qhov chaw plenum (cov kav cua): xav tau CMP

Cov kav dej ntsug (nruab nrab ntawm cov plag tsev): xav tau CMR

Chaw ua haujlwm dav dav/kev lag luam (ib pem teb): CM feem ntau txaus

Sab Nraud/Chaw Nyob/Sab Hauv Txwv: CMX (Saib cov kev txwv hauv zos)
