Lub hauv paus rau phau ntawv
Cov roj fiber ntau lub cav, suav nrog "Fiber ntau Cords," yog qhov tsis tseem ceeb ntawm kev sib tham niaj hnub thiab cov ntaub ntawv network. Cov cables txuas ntxiv ua qhov tseem ceeb ntawm cov khoom tseem ceeb ntawm cov khoom siv kho mob, ua kom qhov kev sib kis ceev, kev sib kis tau qis ntawm cov ntaub ntawv hla cov ntaub ntawv hla kev sib txuas. Raws li tus kws tshaj lij choj nrog dhau kaum xyoo ntawm kev paub hauv kev sib txuas lus kho mob, Kuv yuav tshawb xyuas cov khoom siv hluav taws xob kev sib txuas lus, lawv cov ntawv thov, thiab kev txiav txim siab tseem ceeb rau kev xa tawm.
Anatomy ntawm cov fiber ntau optic thaj cable
Ib qho teeb meem fiber ntau cov khoom siv cable cable cable peb cov ntsiab lus tseem ceeb:
Kho Qhov Muag Fiber: Feem ntau ua los ntawm Silica iav los yog yas, cov tub ntxhais fiber ntau (8-62.5 μm inch) cov phiaj xwm teeb pom kev zoo tag nrho. Ib hom-hom (smf) thiab ntau hom fibers (MMF) yog ob pawg thawj coj.
Cladding Thiab Tiv Thaiv Txheej: Ib qho qis-refrathare-index cladding puag ncig lub tub ntxhais kom kaw lub teeb. Ntxiv cov khaubncaws (tsis muaj cov txheej txheem ntxiv (tsis muaj zog, lub zog ntawm cov tswv cuab, thiab tsho tiv no) muab kev tiv thaiv tshuab.
Tus sib txuas: Pre-terminated xaus (piv txwv li, LC, SC, STR, lossis MPO, MBO) Xyuas kom meej meej cov kev hloov pauv lossis cov vaj huam sib luag.
Hom Fiber Ntau Zais Cables
Los ntawm Fiber Hom
Ib Leeg-Hom Patch Cables (SMF): Tsim qauv rau kev sib kis mus ntev (piv txwv li, telecom pob txha caj qaum) siv 9/125 μm core / cladding. Kev khiav haujlwm ntawm 1310 nm lossis 1550 nm wavelengths.
Ntau hom Patch Cables (MMF): Optimized for short-reach applications (eg, data centers) with core sizes of 50/125 µm (OM3/OM4/OM5) or 62.5/125 µm (OM1/OM2). Siv 850 nm lossis 1300 nm wavelengths.
Los ntawm Connector Hom
Lc (lucent connector): Kev cog lus cog lus, dav siv nyob rau hauv lub siab ib puag ncig.
SC (Cov Neeg Txuas Khoom Txuas): Ua kom muaj zog SNAP-hauv kev tsim rau cov tes hauj lwm lag luam.
MTP / MPO: Multi-Fiber Connectors (12-24 fibers) rau parallel optics hauv 40G / 100g / 400g tshuab.
Los ntawm polarity
Ncaj-los ntawm (yooj yim) lossis duplex kev teeb tsa. Kev tswj hwm polarity yog qhov tseem ceeb rau kev sib txuas lus Bidirectional (piv txwv li TX / RX sib ncab).
Cov Ntawv Qhia Tseem Ceeb
Cov Chaw Teev Khoom: Interconecting servers, hloov chaw, thiab cov tshuab cia thiab cia nrog OM4 / OM5 MMF rau 100G-400G Ethernet.
Telecom Tes hauj lwm: Smf jumpers rau ftth (fiber-rau-hauv-tsev) thiab 5g fronthaul / backhaul.
Enterprise Networks: Txuas cov khoom siv ua haujlwm ntawm kev sib sau ua ke.
Kev lag luam thiab kho mob: Harsh-ib puag ncig-rated cables cov ntaub ntawv lossis endoscopes.
Qhov tseem ceeb ua tsis tau
Thaum xaiv cov cable fiber ntau, ntsuas:
Kev nkag mus tsis tau (Il): Feem ntau<0.3 dB for premium connectors. Excessive loss degrades signal integrity.
Rov qab poob (RL): >40 dB (SMF) or >35 DB (MMF) kom txo qis reflections.
Cable ntev: Zam kev tshaj qhov siab tshaj plaws ncav cuag cov lus uas muaj fiber ntau thiab transceiver fais fab.
Khoov tshuab hluav taws xob: Tswj kom muaj ntau dua lossis sib npaug rau 10 x cov cable hla kom tiv thaiv microbently poob.
Kev coj ua zoo tshaj plaws rau kev xa tawm
Soj ntsuam cov txuas: Siv tsom iav fiber ntau los xyuas cov tshuaj kis lossis khawb.
Zam kev ntxhov siab: Tsis txhob de los yog hla-khoov cables. Siv khoov-insensitive fiber ntau (BIF) qhov kev hloov tau zoo yog qhov yuav tsum tau ua.
Sau npe thiab cov ntaub ntawv: Meej meej cables los ua kom yooj yim daws teeb meem.
Kev huv: Hmoov av kaus mom thiab cov ntaub so lim dej dawb yog qhov tseem ceeb kom tsis txhob muaj kev cuam tshuam cov particulate-indles tsis ua tiav.
Yav Tom Ntej
Cov thev naus laus zis zoo li 800G / 1.6T Ethernet, co-ntim cov khoom lag luam, thiab quaredded sib txuas lus cables nrog sensors rau kev tshuaj xyuas lub sijhawm tiag tiag.
Tag
Fiber ntau Optic Patch cable yog unsung heroes ntawm kev sib txuas nrawm. Lawv cov kev ua tau zoo cuam tshuam cuam tshuam network kev ntseeg tau thiab thev taus. Los ntawm kev nkag siab tias lawv cov qauv tsim qauv, ua raws li kev saib xyuas kev lag luam (piv txwv li kev ua kom nruj kev saib xyuas kev lag luam network (}
