Txais tos mus yuav cov armored simplex fiber ntau thaj qaum lc/apc rau sc/apc rau ruaj khov khib-rau- khib optical txuas, lszh, tiv thaiv- nas, 10m nrog peb lub Hoobkas. Raws li ib qho ntawm cov ua lag luam thiab cov muag khoom nyob rau hauv Suav teb, peb kuj txais tos cov customized txiav txim. Tham tus nqi thiab cov lus hais nrog peb tam sim no.
Cov qauv thiab cov khoom tsim tau tsav los ntawm Network Stability
Tus nqi tseem ceeb ntawm armored fiber ntau thaj qaum tsis yog tsuas yog "muaj zog," tab sis hloov ntau hom kev ua haujlwm tsis zoo-xws li compression, nro, ntau dhau bending, twisting, thiab nas puas tsuaj-los ntawm cov xwm txheej uas cuam tshuam ncaj qha rau cov tub ntxhais fiber ntau (ua rau micro-bending poob) rau hauv kev ntxhov siab los ntawm cov qauv siv thiab tswj.
Kev tsim qauv kev lag luam paub tab feem ntau siv cov txheej txheem tsim:
- Stainless hlau raj (interlocked los yog kauv qauv)
- Aramid xov paj tensile reinforcement
- Lub tsho tiv thaiv sab nrauv
Hauv qhov kev teeb tsa no, lub raj hlau sab hauv muab kev sib tsoo thiab kev tiv thaiv lub cev tiv thaiv - nas barrier, thaum tseem tswj hwm qhov qis qis qis. Lub aramid yarn txheej absorbs tensile rog, thiab lub tsho sab nrauv tiv thaiv kev puas tsuaj thiab txhawb kev txheeb xyuas.
Anti-Rodent Design Logic: Physical Barrier First
Los ntawm qhov kev xav ntawm engineering, kev ua haujlwm tiv thaiv - nas yuav tsum nkag siab tias yoglub cev barrier qhov tseem ceeb.
Hauv kev xa tawm tiag tiag, kev cia siab rau lub tsho ntxiv rau cov nas tiv thaiv yog qhov tsis sib xws thiab nyuaj rau kev txheeb xyuas. Nyob rau hauv sib piv, hlau armor (xws li steel daim kab xev los yog steel tubing) muab ib tug ncaj thiab ntsuas txheej tiv thaiv.
Cov ntaub ntawv kev lag luam los ntawm cov tuam txhab ua lag luam qhia tau hais tias qhov ntev - kev ntsuas lub sij hawm tsis tu ncua qhia tau tiashlau armor (xws li, corrugated steel daim kab xev)yog ib qho kev daws teeb meem zoo tshaj plaws rau kev txhim kho nas tsis kam. Stainless hlau kuj tseem siv dav hauv cov qauv tsim, nrog rau tus nqi -kev ua lag luam kev ua tau zoo- tawm nyob ntawm daim ntawv thov.
Qhov no muab qhov tseeb thiab technically grounded rationale rau kev sib txuasarmored qauv nrog anti- nas muaj peev xwm.
Bending Performance thiab Stability: Dual -Txheej Txheej Txheej Txheem
Thawj txheej yog fiber ntau nws tus kheej. Yog tias ITU-T G.657.A2 ib leeg- hom khoov- tsis muaj fiber ntau raug xaiv, tus qauv qhia meej meej lub hom phiaj ntawm qhov chaw- txwv qhov xwm txheej xws li "siab-qhov ceev fiber ntau tswj tshuab thiab cov ntaub ntawv chaw sib txuas," thiab qhia qhov tsawg kawg nkaus lub vojvoog tsim rau A21.5mm (A). Tsis tas li ntawd, G.657.A tau piav qhia tias yog ib feem ntawm G.652.D (tshwj xeeb hauv kev sib cuam tshuam thiab kev sib txuas lus), txhawb kev sib koom tes nrog OS2 ecosystem uas twb muaj lawm.
Cov txheej txheem thib ob yog cov qauv siv cable. Cov hlau txuas thiab sab nraud ntawm cov hlua khi armored ua rau "tso cai dabtsi yog khoov vojvoog" mus rau kev tsim khoom ntau dua - tus nqi tswj tau, thiab cov qauv kev txwv tsis pub dabtsi yog khoov hauv qab lub vojvoog pom zoo, yog li txo qis qis dua thiab ntev -lub sij hawm kev ntxhov siab los ntawm micro-bending / macro{2}.
Tsawg Insertion Loss thiab High Return Poob (Core ntawm APC Stability)
APC (Angled Physical Contact) cov khoom txuas feem ntau muaj qhov kwv yees li 8℃angled kawg lub ntsej muag, uas geometrically redirects reflected lub teeb mus rau cladding, txo qhov kev xav rov qab mus rau qhov chaw.
Hauv kev xyaum ua haujlwm engineering, "APC Ntau dua lossis sib npaug ntawm 60 dB rov qab poob" feem ntau yog siv los ua lub hom phiaj rau kev xav txog kev kub ntxhov siab (feem ntau yuav tsum siab dua UPC). Qhov no yog vim li cas APC feem ntau xaiv rau siab - ruaj khov cov ntaub ntawv chaw txuas thiab kev xav txog - cov kab ke rhiab heev xws li PON / CATV.
LSZH (Low Smoke Zero Halogen) thiab Data Center Safety Stability
Tus nqi ntawm LSZH tsis yog tsuas yog "kev phooj ywg ib puag ncig," tab sis kuj txo qis "scope ntawm downtime" nyob rau hauv cov ntaub ntawv chaw teeb meem scenarios.
Cov keeb kwm ntawm IEC 60754-1 tau hais meej meej tias qee cov ntaub ntawv cable tso tawm cov kua qaub thaum hlawv, uas tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob thiab hluav taws xob ntau dhau ntawm qhov hluav taws kub nws tus kheej. Tus qauv muab txoj hauv kev los txiav txim siab halogen acid roj cov ntsiab lus, tsim lub hauv paus rau kev txwv cable txwv.
Ua ke nrog IEC 61034 series (kev ntsuas pa taws ntom ntom) thiab IEC 60332 nplaim hluav taws retardancy kuaj qhov system, LSZH coj hluav taws kub -txog kev pheej hmoo- xeb, pa taws, thiab nplaim taws kis tau - mus rau hauv lub hauv paus kev ua raws li qhov tseeb.
EMI Kev Tiv Thaiv Kev Tiv Thaiv (Cov Ntawv Ceeb Toom Siv Tau)
Fiber optics xa cov teeb liab siv lub teeb es tsis yog hluav taws xob tam sim no, thiab qhov nruab nrab tsis yog -conductive. Yog li ntawd, nyob rau theem txuas, fiber ntau inherently tiv thaiv electromagnetic cuam tshuam (EMI).
Nyob rau hauv ib puag ncig xws li siab -racks ceev, sib npaug routing nrog lub hwj chim cables, los yog thaj chaw uas muaj suab nrov electromagnetic nyob rau hauv cov ntaub ntawv chaw, tus yam ntxwv no ncaj qha txhim kho cov stability txwv ntawm me ntsis yuam kev tus nqi thiab txuas jitter.
Txo cov ntsiab lus txuas tsis ua haujlwm nrog kev txuas ntxiv 10m Optical Txoj Kev
Hauv cov kab ke tsim qauv, txhua qhov kev sib txuas ntxiv txuas ntxiv qhia txog cov teeb liab poob, tsis ruaj khov, thiab ntev - kev pheej hmoo txij nkawm ntev.
Ib qho 10-meter armored simplex fiber optic thaj qaum yog tsim los rautshem tawm cov ntsiab lus txuas tsis tsim nyog, tsim kom muaj kev ruaj khov thiab muaj txiaj ntsig ntawm qhov txuas kho qhov muag.
Yuav Ua Li Cas Txhim Kho Network Stability
Tsawg dua kev sib txuas Interfaces:Ib qho txuas txuas ib leeg 10m cable hloov ntau qhov luv luv patch cords thiab adapters, txo cov ntsiab lus ntawm lub cev tsis ua haujlwm.
Lower Insertion Loss Accumulation:Txhua qhov kev sib txuas feem ntau qhia txog 0.2-0.3 dB poob. Tshem tawm cov interfaces ntxiv pab tswj kom pom lub teeb pom kev zoo.
Consistent Rov Loss Performance:APC connectors (8℃angled polish) kom ruaj khov rov qab poob, txo cov teeb liab cuam tshuam thoob plaws tag nrho qhov txuas.
Xaus-rau-Xaum Teeb Meem Kev Ncaj Ncees:Ib txoj hauv kev txuas txuas ntxiv kom tsis txhob cuam tshuam, ua kom muaj kev sib kis tau zoo dua nyob rau hauv siab -xav tau ib puag ncig.
Daim ntawv thov scenarios thiab siab -Cov lus pom zoo rau kev xa tawm
Cov ntaub ntawv chaw topology thiab redundancy tsim hais txog tias ib qho ntawm qhov tsis ua haujlwm tuaj yeem ua rau muaj kev pheej hmoo ua lag luam. Yog li ntawd, nyob rau ntawm thaj chaw qaum, kev ruaj ntseg thiab rov ua dua yuav tsum raug tsim kho kom raug. ANSI/TIA-942-C txhais qhov tsawg kawg nkaus kev sib txuas lus infrastructure yuav tsum tau rau cov chaw zov me nyuam cov ntaub ntawv thiab cov chav computer, nrog rau cov ntsiab lus ntawm redundancy thiab muaj tiers. ISO / IEC 24764 tseem qhia meej txog kev siv fiber ntau thiab tooj liab cabling hauv cov chaw zov me nyuam.
Nyob rau hauv lub moj khaum no, armored LSZH tiv thaiv - nas thaj qaum yog nyob rau muab ib tug ntau txhim khu kev qha "kawg 10 meters" lub cev txheej kev ruaj ntseg rau kev sib tshuam tseem ceeb.
Cov ntawv thov raug suav nrog:
Hla -kev sib txuas ntawm thaj vaj huam sib luag / ODFs thiab ToR keyboards lossis optical modules nyob rau hauv ib lub khib (los yog nruab nrab ntawm racks hauv tib kab)
Luv-kev sib tshuam deb hauv siab- qhov sib txawv ntawm qhov ntom ntom
Routing los ntawm ODF mus rau cov khoom siv hauv cov kav dej lossis ib puag ncig uas qhov kev teeb tsa txuas ntxiv nyuaj
Xaus-rau- xaus patching Cheebtsam hauv A/B redundant link architectures
Daim duab qhia txog ob lub ntsiab lus tseem ceeb ntawm kev ruaj ntseg:
Muab qhov "siab-qhov chaw nres nkoj ceev" rau ntawm LC connector kom muaj qhov chaw nres nkoj siab dua thiab kev tswj xyuas cov kab hluav taws xob zoo dua, thaum siv SC txuas rau sab faib rau kev ua haujlwm ODF txheem.
Siv armored patch cords nyob rau hauv cov cheeb tsam uas feem ntau yog compression, dabtsi yog khoov, stepping, los yog txhob txwm rub -xws li nyob rau hauv racks thiab ze ntawm -kawg routing zones-thaum ua kom ntseeg tau tias txoj hauv kev rov qab ua raws li cov ntaub ntawv chaw nruab nrab rau kev sib cais thiab rov ua dua.
