To taub Fiber Optic Cable Jacket & Hluav Taws Kub Ntaus Hluav Taws Xob
Fiber optic cable yog tsim los ntawm cov hauv paus hauv plawv, cladding, txheej, muaj zog rau cov neeg sab nrauv cable tsho. Raws li cov mis nyuj khov yog yooj yim tawg, fiber optic cable tsho yuav tsum tau muab kev tiv thaiv rau lub shielding thiab conductors nyob rau hauv lub cable. Lub tsho cable yog thawj kab ntawm ya raws, txhua yam, nplaim taws thiab tshuaj tiv thaiv rau ib tus fiber ntau cable.
Fiber Optic Cable Jacket Khoom
Fiber cable tsho yog tsim los ntawm ntau hom ntaub ntawv. Nws yog ib qho tseem ceeb uas yuav tsum xav txog lub hnab tsho thaum xaiv cov kev sib tw nrog cov ntawv sib txuas lus thiab qhov chaw nyob. Cov lus hauv qab no muaj qee cov hom khoom siv fiber ntau tshaj plaws uas siv sab hauv tsev thiab sab nraum zoov:
| Cov khoom hnav | Nyiaj ntawm Jacket Khoom |
|---|---|
| PE (Polyethylene) | PE muaj cov khoom zoo heev ntawm kev ya raws thiab huab cua tsis haum, thiab muaj cov khoom hluav taws xob zoo nyob rau ntau qhov chaw kub. Nws tseem yog cov uas tiv taus. Yog li PE yog cov khoom siv tsho dav rau sab nraum zoov fiber ntau optic cables . |
| PVC (Polyvinyl Chloride) | PVC yog feem ntau qes-nqi, hloov tau yooj yim, rugged haum, thiab nplaim / roj-resistant khoom, yog li nws tau formulated ua haujlwm nyob rau hauv ntau yam kev kawm thiab kev siv. Hauv lwm lo lus, nws tuaj yeem siv ua cov ntaub ntawv tsho rau sab hauv tsev thiab sab nraum zoov. |
| PVDF (Polyvinyl Difluoride) | PVDF yog siv rau plenum cables, vim nws muaj cov khoom hluav taws kub zoo dua PE thiab ua rau me nyuam haus luam yeeb tsawg. |
| LSZH (Tsawg Haus Luam Yeeb Xoom Halogen) | LSZH lub tsho yog dawb ntawm cov ntaub ntawv halogenated uas tau hloov mus rau qhov tshuaj lom thiab corrosive matte thaum lub sij hawm combustion. LSZH cov ntaub ntawv yog siv los ua ib lub koob yees duab tshwj xeeb hu ua LSZH cable, uas yog kev xaiv zoo rau cov kev sib puab. Tab sis nws yog cov tsho kim tshaj plaws. |
Fiber Optic Cable Jacket xim xim
Raws li EIA / TIA-598, fiber optic cable colour code qhia lub tsho xim xim rau ntau hom fiber ntau (SMF lossis MMF). Rau tib hom fiber , lub tsho xim yog feem ntau yog daj. Thaum rau cable ntau hom, lub tsho xim yuav ua rau txiv kab ntxwv (OM1 & OM2 cable), aqua (OM3 cable) thiab ntshav (OM4 cable). Rau sab nrauv cog cables, tus qauv tsho xim dub. Yog xav paub ntxiv txog fiber optic cable colour code thov hu rau Fiber Optic Cable Color Code li cas?
Fiber Optic Cable Qhov Kev Ntsuam Xyuas Hluav Taws Xob
Feem ntau, muaj yim theem ntawm cov hluav taws tsis ua haujlwm rau ob leeg uas tsis muaj kev sib txuas thiab cov kab hluav taws xob uas teev los ntawm NEC (National Electrical Code). Tag nrho cov fais fab hauv chaw tsim hluav taws xob hauv hluav taws xob yuav tsum raug cim thiab ntsia kom zoo rau nws cov kev siv: plenums, risers thiab chaw dav dav.
Nco Ntsoov:
(1) Ib qho Plenum hauv cheeb tsam yog ib qho chaw siv rau kev siv cua khiav lossis cua tshuab pa (tshem tav thiab tsa cov plag tsev).
(2) Ib thaj chaw muaj thaj chaw yog lub plag zom zaws, lub taub hau los yog cov ciav uas khiav ntawm ib los yog ntau plag tsev.
(3) Ib qho chaw dav dav yog tag nrho lwm qhov uas tsis yog plenum lossis riser thiab nyob rau tib lub floor.
| NEC Code | Kev piav qhia | Daim Ntawv Thov Kev Pabcuam | Tau Hloov Tau |
|---|---|---|---|
| OFNP | Optical Fiber Non-conductive Plenum Cable | Plenum, nyiaj siv ua haujlwm, fiber ntau xwb | / |
| OFCP | Optical Fibre Infenum Cable | Plenum, nyiaj siv ua haujlwm, veg (fiber / xaim) | / |
| OFNR | Optical Fiber Tsis Txhob Lawm Kab Mob | Riser, qaum, fiber ntau xwb | OFNP |
| OFCR | Optical Fiber Kab Mob Rise Cable | Riser, qaum, hybrid | OFCP |
| OFNG | Optical Fiber Txheej txheem General-Purpose | Lub hom phiaj dav dav, kab rov tav | OFNP, OFNR |
| OFCG | Optical Fiber Conductive General-Purpose | Lub hom phiaj | / |
| OFN | Optical Fiber Tsis Nqis | Lub hom phiaj dav dav, kab rov tav, fiber ntau xwb | OFNP, OFNR |
| OFC | Optical Fiber Conductive | Lub hom phiaj, dav, hybrid | OFCP, OFCR |
OFNP thiab OFNR
Raws li tau hais los saum no, OFNP thiab OFNR yog ob hom fiber ntau fiber ntau uas siv hauv tsev. OFNP cables muaj hluav taws ua xyaw thiab cov pa luam yeeb tsawg tsawg. Qhov no yog qhov hluav taws xob ntau tshaj tawm hluav taws xob thiab tsis muaj lwm hom kab mob sib tw siv tau. Yog li cov cables no feem ntau ntsia hauv plenum cheeb tsam. Whereas, cov fiber ntau-ua thiab tsis tshua muaj pa ntawm OFNR cables tsis zoo li OFNP. OFNP plenum cables yuav siv tau cov khoom hloov chaw rau OFNR cables. Los ntawm OFNR thiab OFNP, nws tsim nyog lees paub tias OFNR fiber optic cable tsis tau siv hauv plenum cheeb tsam los hloov OFNP cables, tab sis, tom kawg, siv tau rau hauv cov chaw riser. Ob leeg OFNP thiab OFNR siv tau rau hauv cov hom phiaj dav dav.
FOCC Plenum / Riser Fiber Optic Cable Solutions
Nyob rau hauv lub nutshell, plenum rated thiab riser rated cables feem ntau deployed nyob rau hauv cov tuam tsev. Kev xaiv hom kab ntsuas cov khoom muaj peev xwm ua kom tsis txhob poob thaum cov cables hlawv. Yog hais tias koj daim ntawv thov cabling yuav tsum tau cov ntaub ntawv uas muaj hluav taws xob los yog ua raws li cov txheej txheem kev ruaj ntseg, thov nco ntsoov xaiv cov kab hluav taws xob ntsuas. FOCC muab cov kab mob plenum thiab riser fiber ntau, xws li cov kab mob MTP plenum, cov kab mob MTP-LC plenum kab hlau , cov cuab yeej ceev ntim cov plenum cables , cov hlua nrawm ntawm lub plenum plenum cables , thiab cov kab sib tsoo ceev nrawm / tawg.
