Cov Khoom Siv Hluav Taws Xob Fiber Optic yuav tsum muaj cov chaw nres nkoj tshwj xeeb

 

 

Kuv tau ua haujlwm nrog network infrastructure rau txog xya xyoo tam sim no, thiab yog hais tias muaj ib yam uas nws tau muaj fiber ntau nrog fiber ntauOptic HloovCov. Koj yuav xav tias chaw nres nkoj tsuas yog chaw nres nkoj xwb, txoj cai? Plug thiab ua si? Tsis txawm nyob ze.

 

 

Qhov chaw nres nkoj tsis muaj leej twg tham txog qhov txaus

 

Ntawm no yog muaj dab tsi tshwm sim: tuam txhab txiav txim siab hloov kom muaj fiber ntau vim tias "nws nrawm dua" (nws yog, tab sis qhov ntawd ib sab ntawm lub ntsiab lus). Lawv yuav cov tes no, cov khoom kim heev dhau, thiab tom qab ntawd ib tug neeg- Kuv tau pom ib yam dab tsi uas lawv tau pom ua ntej. SFP SLOTS yog qhov khoob. Muaj lub sijhawm no ntawm ceeb. Muaj nyob ntawd.

Qhov yog, cov tshuab hluav taws xob fiber ntau tsis tuaj nrog ua -}} hauv cov chaw nres nkoj tib txoj kev tooj liab mus ua. Lawv siv cov kev hloov pauv modular, thiab cov feem ntau koj yuav khiav mus rau IS SFP (daim ntawv me me-}}}} qhov tseeb pluggable) thiab SFP + modules. Cov rooj sib tham uas tsis txaus ntseeg vim tias SFP + suab zoo li nws yuav tsum tsuas yog ua kom zoo dua qub ntawm SFP, tab sis lawv tsis tshua muaj kev sib pauv tau ntau dua li koj xav. SFP MAXES tawm ntawm 1 Gbps thaum SFP + XWM 10 GBPS. Tom qab ntawd muaj QSFP rau 40 Gbps, QSFP28 rau 100 Gbps, thiab kev ncaj ncees cov niam ntawv cov niam ntawv tsuas yog mus.

 

Vim li cas qhov kev hloov kho no muaj nyob (thiab vim li cas nws ob leeg ci ntsa iab thiab ntxhov siab)

 

 

Cov qauv uas tau ua tiav ua tau zoo ib zaug koj tau txais yav dhau los thawj mob taub hau. Cov hom sib txawv uas xav tau cov opt optics. Koj tau txais ib qho - hom fiber uas tuaj yeem khiav mus rau cov khoom siv tau yooj yim rau xyoo pua no, 80} Koj tsis tuaj yeem siv tib transceiver rau ob qho tib si vim tias nthwv dej yog sib txawv kiag li.

Ib qho -} hom feem ntau khiav ntawm 1310nm lossis 1550nm wavelength. Multimode? Feem ntau 850nm. Lub optics yuav tsum tau phim lossis koj tsuas yog tua lub teeb rau hauv cable thiab vam rau qhov zoo tshaj plaws, uas tsis ua haujlwm. Txhua. Kuv twb pom cov neeg sim.

Dab tsi tiag tiag tau kuv yog tias txawm li ntawd txawm nyob hauv tib qeb, koj tau txais kev hloov pauv. Nqa SFP + Modules rau ib leeg- hom fiber ntau {} Muaj cov version (lr), 80km (ZR), thiab txawm tias ncua ntev. Txhua tus siv cov tshuab laser sib txawv, cov peev nyiaj kho tau zoo. Lub 80kM module yuav raug nqi tsib zaug ntau dua li 10km version, thiab lawv saib zoo ib yam ntawm sab nraud. Koj yuav tsum nyeem cov ntawv me me ntawm sab, thiab hmoov zoo ua qhov ntawd hauv chav ua hauj lwm tsis zoo.

 

Kev Koom Tes Nyiaj Txiag

 

Qhov no yog qhov uas tau nthuav, lossis kev txaus siab, nyob ntawm koj cov nyiaj txiag peev. Ib qho kev ua haujlwm zoo -}}}}}}}}}}}}}}}}}}}}}}}}}}} hloov chassis tej zaum yuav khiav koj $ 8,000 rau $ 15,000. Suab kim, tab sis tos - uas tsuas yog lub thawv khoob. SFP + transceivers? Txhua tus tuaj yeem nyob txhua qhov chaw ntawm $ 150 txog $ 800 nyob ntawm hom thiab specs. Xav tau 24 chaw nres nkoj? Ua lej. Thiab saum ntuj txwv tsis pub koj xav tau cov khoom siv ntau yam ntxiv lossis cov khoom DWDM.

Qee tus neeg sim txuag nyiaj los ntawm kev yuav thib peb -} kev hloov tog tog. Qee zaum qhov no ua haujlwm zoo. Qee zaum nws kiag li tsis, thiab koj cov phanted phantom pob ntawv poob ntawm 3 AM vim tias tus hloov pob ua si tsis zoo nrog lub tawm ntawm- hom brandics. Cisco tsis muaj npe rau kev kus paub txog qhov no {6} Lawv hloov chaw ntau zaus yog tias nws tsis pom zoo "yog tias nws tsis raug pom zoo". " Koj tuaj yeem tiv thaiv cov lus ceeb toom no, tab sis tom qab ntawd koj tau muab daim ntawv cog lus txhawb nqa koj. Lub sijhawm lom zem.

 

Lub Txuas Kev Ua Si

Tom qab ntawd muaj tag nrho cov teeb meem txuas, uas tsim nyog nws tus kheej rant. LC txuas tau zoo nkauj ntau dua tam sim no rau ib qho -}}}} Kuv me me, thiab lawv xauv nyob rau hauv qhov chaw nrog kev txaus siab nyem. Tab sis multimode nruab qee zaum tseem siv sc txuas, uas yog cov khoom loj no uas koj yuav tsum thawb hauv thiab sib ntswg. Thiab yog tias koj ua haujlwm nrog cov txheej txheem qub dua, tej zaum koj yuav khiav mus rau hauv cov stillors, uas yog puag ncig nrog ib tug bayonet {{5} Cov style xauv. Sim ua kom taug qab cov thaj uas koj xav tau rau qhov teeb tsa uas yog nws tus kheej tshwj xeeb hom kev sib tw.

Kuv ib zaug tau siv tag nrho yav tav su nrhiav ib qho LC {{0} {{1} {1} {1} {1} {1} {1} Kev tswj kev tswj hwm ntawm cov xim hloov chaw. Lub cable yog txiv kab ntxwv. Txhua yam fiber yog txiv kab ntxwv lossis daj lossis qee zaum xiav yog tias nws yog ib leeg {{} hom. Pab tau heev.

 

 

Polarity thiab ob - fiber ntau

 

Nov yog qee yam uas tsis tau piav qhia zoo nyob rau hauv feem ntau cov ntaub ntawv: Fiber ntau yog unidirectional. Koj xav tau ob txoj kev strands -}} ib qho rau xa, ib qho kom tau txais. Tus Transceiver muaj ib sab ntawm tus mob ntsws thiab ib sab rx, thiab koj yuav tsum tau txais txoj cai polarity. Txuas cov roj rau TX thiab RX rau RX, thiab koj zaum nyob ntawd xav paub tias yog vim li cas qhov txuas yuav tsis los. Nug kuv tias kuv paub li cas.

Qee cov thev naus laus zis tshiab xws li BIDI (Bidirectional) Optics tuaj yeem khiav ob qho tib si cov lus qhia ntawm ib qho fiber ntau strand siv wavelengths, uas yog qhov ntse heev. Tab sis cov uas yog tshwj xeeb, kim kim, thiab koj tsis tuaj yeem tsuas yog sib pauv lawv mus rau hauv tus qauv kev teeb tsa yam tsis tau tshuaj xyuas kev sib raug zoo. Txhua yam hauv fiber ntau yuav tsum tau kuaj xyuas kom haum. Nws sab hauv.

Tag nrho cov teeb meem polarity tau txais ntau yam ntxiv nrog MPO / MTP cov txuas txuas siv hauv 40G thiab 100g daim ntawv thov. Cov no yog txoj kev sib txuas nrog 12 lossis 24 tus kab hauv ib qho txuas, thiab koj tsis yog kho ib qho txuas, thiab koj tsis yog kho ib qho kev txiav txim siab tag nrho CABLE. Kuv tsis xav tham txog tias yuav siv sijhawm ntev npaum li cas.

 

Kev sib txuam ceev thiab autonegotiation (lossis tsis muaj nws)

 

Tooj liab ethernet muaj autonegotiation. Nws tsis zoo tag nrho, tab sis nws ua haujlwm feem ntau. Ob lub tshuab xuas tes ua, xam tawm nrawm nrawm nrawm nrawm, thiab koj mus. Fiber ntau? His. Kev hloov pauv fiber ntau yog tsau - ceev. SFP Module yog 1G. SFP + Module yog 10G. Koj tuaj yeem nres 10G module ntawm 1G ceev yog tias tus hloov hloov txhawb nws thiab koj teeb tsa nws tus kheej, tab sis nws tsis yog lees paub.

Qhov no tsim cov teeb meem tiag tiag hauv kev sib xyaw - ceev cov chaw. Koj tsis tuaj yeem tsuas yog plug ib tus neeg rau zaub mov nrog lub 10g fiber nic rau hauv ib qho chaw nres nkoj hloov nrog 1g SFP module thiab cia siab tias nws yuav ua haujlwm, txawm tias lub cev sib txuas haum zoo. Lub optics yuav tsis sync. Lub txuas nyob qis qis. Tom qab ntawd koj tab tom yuav cov qauv sib txawv lossis rov qab ua kom koj cov network topology.

 

Kub ntsuas teeb meem ntau dua li koj xav

Industrial -} transce transceivers muaj rau qhov laj thawj. Cov Qauv Kev Lag Luam Optics yog nyob rau tej zaum 0 Qib rau 70 degree. Qhov ntawd yog qhov zoo rau kev nyab xeeb rau - tswj cov ntaub ntawv cov ntaub ntawv. Tab sis yog tias koj txhim kho cov pob zeb, lossis lub xov tooj ntawm tes ntau dua, koj xav tau txias heev, koj xav tau txias kev lag luam rau -40℃rau 85 degree. Cov nqi no tseem ceeb dua.

Kuv tau ua haujlwm ntawm ib qho haujlwm uas ib tus neeg siv coj kev lag luam {{}}}}}}} qib SFP + cov qauv hauv lub txee sab nraum zoov. Ua haujlwm zoo nyob rau lub caij nplooj ntoo hlav. Lub caij ntuj sov ntaus, lub txee rau lub cev hauv Temi 500 Degree, thiab transceivers pib ua tsis tiav. Sib tw sib txawv yog qhov phem tshaj vim tias koj siv sijhawm ua ntej hnub koj paub tias qhov teeb meem kub yog qhov ntsuas kub. Peb xaus li hloov 32 modules. Lub ncua - temp versions raug nqi txog 40% ntau dua ib chav.

 

 

Cov nyiaj txiag hluav taws xob thiab kho qhov muag

 

Qhov no tau txais kev nrawm, tab sis cov tswv yim yooj yim yog tias txhua lub fiber ntau cov kev sib txuas qhia txog kev poob. Connector ntxiv txog 0.5 DB ntawm kev poob txhua. Sples Add 0.1 txog 0.3 DB. Lub fiber nws tus kheej tau attenuation - Feem ntau nyob ib ncig ntawm 0.5 DB / KM rau ib leeg {8nm, tsawg dua thaum 1550nm. Koj ntxiv tag nrho cov no, thiab koj tau txais koj qhov txuas tag nrho.

Tus transceiver muaj cov nyiaj txiag hluav taws xob - Qhov sib txawv ntawm hloov zog thiab txais rhiab rhiab. Rau ib txwm muaj 10g LR module, koj yuav muaj -1 dBM xa hwj chim thiab -14.4 DBM tus txais kev paub zoo, muab koj 13.4 DB ntawm cov nyiaj fais fab. Koj qhov kev ua tiav yuav xav tau tsawg dua li ntawd, nrog qee cov npoo rau kev ua tsis tiav sijhawm.

Hauv kev coj ua, koj tsis tshua ua cov kev suav ntawm kev ua haujlwm ntxiv vim tias cov ntaub ntawv los ntawm cov npe nrov moduable codule tuam ntxhab qhia koj qhov kev ntsuas ntsuas. Tab sis thaum koj thawb kev ncua deb rau qhov txwv, lossis thaum koj daws teeb meem txuas, nkag siab qhov muag hluav taws xob kho qhov muag tau dhau los ua qhov tseem ceeb. Koj xav tau lub ntsuas hluav taws xob kho qhov muag, uas yog lwm $ 300 txog $ 2000 raws cov yam ntxwv.

 

Lub DWDM luav qhov

 

Dirt Wavelength division multiplexing yog qhov twg tau ua kom zoo. Hloov chaw ntawm kev siv ib lub wavelength ib fiber, DWDM cia koj khiav ntau yam wavelengths {}} 32, 96, txawm ntau-rau ib fiber ntau. Txhua lub nthwv dej yog qhov tseem ceeb ib cais 10g lossis 100g channel.

Cov kev hloov pauv rau DWDM tau tuned rau cov wavelengths rau ntawm iTU kab sib chaws. Muaj 96 channel 50 ghz sib nrug hauv c - band (1530nm rau 1565nm cheeb tsam). Koj yuav tsum tau taug qab qhov twg transceer yog nyob rau ntawm lub wavelength, thiab lawv yog xim - coded tab sis cov xim tsis sib haum rau hauv txoj kev intuitive. Channel 29 yog ntshav. Channel 30 yog liab. Vim li cas? Tsis muaj vim li cas.

DWDM tau siv nyob rau hauv ntev - haul applicions thiab cov ntaub ntawv chaw ua haujlwm uas fiber ntau thiab kim. Kev hloov pauv tau them ntau dua, koj xav tau ntau yam kev hloov pauv, thiab cov khoom siv kub thiab txias tau dhau los ua cov nthwv dej tau tuaj yeem ua rau cov Crosstalk.

 

Software kev teeb tsa tsis yog ib txwm ncaj

Txawm tias tom qab koj tau txais txoj cai hloov lub cev, koj tsis tau ua. Ntau lub tshuab xa hluav taws xob yuav tsum tau ua kom pom qhov chaw nres nkoj ceev, hom uas yuav tsum tau tag nrho rau fiber, tab sis kuv tau pom cov kab uas txawv txawv), thiab qee zaum pab kom qhov chaw nres nkoj ntawm tus kheej. Qee tus muag khoom siv tsis tau ports los ntawm lub neej ntawd.

Yog tias koj siv DAC (qhia ncaj qha rau tooj liab) Cables rau kev hloov kho tshiab {}}} Txoj kev hloov pauv mus rau hauv ob qho kawg. Tab sis tus hloov mus tseem pom cov li SFP + chaw nres nkoj thiab koj tseem yuav tsum tau teeb tsa lawv. DAC cov cab kuj pheej yig dua Fiber ntau ntxiv rau ob transceiversivers, tab sis lawv tau txwv tsis pub dhau 5 metres thiab lawv tuab thiab inflexible. Kev tswj hwm cable nrog DAC cables tsis lom zem.

 

Tus neeg muag khoom xauv - hauv thiab sib xyaw

 

Qhov loj hloov mus rau cov neeg muag khoom loj - Cisco, Juniper, Arista, Hpe {{} txhua tus xav tau koj yuav lawv cov kev hloov tsheb branded. Cov no feem ntau tsuas yog REBRANDED Modules los ntawm cov chaw tsim khoom optics zoo li finisar, laryum, lossis avago, tab sis nrog tus neeg muag khoom {{} eeprom kev pab cuam. Lub Marcup tuaj yeem yog 300% lossis ntau dua.

Thib peb {- tog optics los ntawm cov tuam txhab zoo li fs.com lossis 10gtek ua haujlwm zoo feem ntau ntawm lub sijhawm. Tus yuam sij yog kom tau coded modules uas txheeb xyuas lawv tus kheej kom raug rau tus hloov. Qee cov neeg muag khoom ua qhov yooj yim dua li lwm tus. Arista yog qhov zoo nkauj qhib li thib peb-} aipt optics. Cisco ... tsawg dua. Muaj tiag tiag ib lub tsev meuv lag luam ntawm cov tuam txhab optics uas tshwj xeeb hauv "Tau tshaj tawm" cov qauv siv khoom muag.

Qhov kev ntxhov siab tiag tiag yog thaum koj ua ntau - Tus neeg muag khoom lub teeb tsa thiab txhua tus neeg muag khoom lub optics siv cov kev sib txawv me ntsis txawm tias ib qho tib teev nrawm thiab deb. Koj tuaj yeem xaus nrog kev sib txuas uas ua haujlwm tab sis qhia cov qhab nia ua yuam kev siab, lossis cov kev txuas uas ua haujlwm tau zoo thaum xub thawj tab sis tsis txaus ntseeg nrawm dua li kev cia siab.

 

Kev ntxuav thiab txij nkawm

 

Tsis muaj leej twg nyiam tham txog kev tu fiber ntau, tab sis nws yog kiag li tseem ceeb. Ib lub plua tshauv ntawm lub endface ntawm cov sib txuas fiber ntau tuaj yeem ua rau cov teeb liab tsis tseem ceeb lossis kev sib txuas ua tiav tsis ua haujlwm. Qhov endefaces yog me me - nyob ib ncig ntawm 9 microns rau ib leeg- hom fiber ntau txoj kab uas hla. Ib qho plua plav yog qhov sib piv.

Koj yuav tsum ntxuav kom huv txhua lub fiber kev sib txuas, txhua lub sijhawm. Kev muaj tiag? Qhov ntawd tsis yog ib txwm tshwm sim rau hauv cov chaw tsim khoom uas koj yuav ua kom muaj kev pabcuam. Tab sis nws yuav tsum tshwm sim. Siv cov cuab yeej zoo fiber ntau - Cov ntaub so tshwj xeeb thiab tu cov pas, tsis yog koj lub tsho. Tshawb xyuas nrog fiber tsom. Tshuab tawm cov ports nrog cua compressed.

Kuv twb muaj teeb meem "kev hloov pauv tsis zoo" uas yog qhov tseeb tsuas yog kev sib txuas qias neeg. Ntxuav cov fiber ntau, teeb meem daws teeb meem. Tab sis koj tsis tuaj yeem pom cov av nrog koj lub qhov muag liab qab, yog li koj tau pov tseg lub sijhawm muab cov khoom siv kho thiab khiav ua haujlwm ua ntej.

 

Yav tom ntej -} ua pov thawj taub hau

Thaum koj tau tsim cov network fiber ntau, koj yuav tsum xav txog kev loj hlob thiab yav tom ntej bandwidth xav tau. Lag, zoo. Tab sis deb npaum li cas rau yav tom ntej? SFP + ntawm 10G zoo li overkill kaum xyoo dhau los. Tam sim no nws tau ua cov hauv paus rau cov neeg rau zaub mov sib txuas. Koj puas khiav OM3 multimode fiber ntau uas yog qhov zoo rau 10g, lossis siv ntau dua rau Om4 uas tuaj yeem lis 40g thiab 100g dhau qhov kev ncua tshwj xeeb?

Ib Leeg - hom fiber yog "yav tom ntej-}}} Qhov kev txwv tsis pub lwm tus muaj transceivers thiab hloov chaw nres nkoj. Tab sis ib qho -} hom nqi them ntau dua rau nruab ntau dua, yuav tsum tau them ntau dua transabilivers, thiab koj yuav tau them nyiaj rau tej zaum koj yuav tsis xav tau xyoo. Lossis koj yuav xav tau nws lwm xyoo. Leej twg paub?

Qhov chaw nres nkoj suav teeb meem muaj feem xyuam. Koj yuav ib qho hloov nrog 48 chaw nres nkoj. Koj populate 30 ntawm lawv pib. Nkawd zoo. Ob xyoos tom qab koj xav tau 52 chaw nres nkoj thiab koj tab tom nruab rau lwm tus hloov, cuam tshuam nrog cov khoom sib tsoo lossis cov ntaub qhwv, ntxiv cov nyom. Puas yog koj yuav tsum tau yuav tus loj hloov upfront? Tej zaum, tab sis nws raug nqi 50% ntxiv thiab tsis muaj tus tuaj yeem lav koj yuav tau loj hlob mus rau hauv nws.

 

Thaum yam tsis ncaj ncees lawm

Kev daws teeb meem cov teeb meem fiber ntau yog nws tus kheej cov txuj ci. Qhov txuas yog down. Vim li cas? Yuav yog:

Qias neeg txuas (huv si thiab kho dua tshiab)

Tsis ncaj transceiver hom (kuaj cov qauv)

Fiber ntau (khiav otdr kuaj yog tias koj muaj ib qho, hmoov zoo yog tias koj tsis)

Tshaj kev ntsuas qhov ntsuas (ntsuas cov cable tiag tiag)

Yoj nthwv dej tsis zoo (xyuas ob qho tib si xaus)

Chaw nres nkoj tsis tau teeb tsa (kuaj xyuas hloov chaw)

Txhaum kev hloov pauv (sib pauv thiab sim)

Polarity Reversed (Khij Cov Txiaj Ntsig Los / RX Kev Sib Txuas)

Lub Hwj Chim Pob Nyiaj Ntau Tshaj Plaws (Ntsuas Hluav Taws Xob)

Software kab laum nyob rau hauv hloov firmware (hloov tshiab thiab thov)

Qhov teeb meem yog, cov kev ua tsis tiav feem ntau saib zoo ib yam ntawm sab nraud. "Tsis muaj qhov txuas" yog txhua yam koj tau txais. Koj pib ua haujlwm los ntawm cov npe, pauv cov Cheebtsam, kom txog thaum muaj qee yam ua haujlwm. Nws tsis muaj kuab heev.

Cov teeb meem sib txawv yog qhov phem dua. Txuas daim flapping, pob ntawv poob uas los thiab mus, yuam kev uas ntsia zoo li hauv lub nra. Cov no tuaj yeem tshwm sim los ntawm marginal kho qhov muag, ntsuas hluav taws xob cuam tshuam, EMI yog tias koj tau khiav ntawm lwm cov khoom siv fais fab, lossis txog kaum ob yam.

 

Qhov kuv xav tau ib tug neeg tau hais rau kuv

Pib nrog cov ntaub ntawv zoo. Taug qab cov transceivers nyob hauv dab tsi hauv cov chaw nres nkoj, dab tsi firmware tau khiav, hom twg loj thiab ntev tau ntsia. Siv cov ntawv pov tseg kom raug. Khaws cov spares ntawm tes vim tias transceivers ploj thiab tos rau kev thauj khoom thaum kev tsim khoom poob qis yog tsis lom zem.

Yuav los ntawm cov neeg muag khoom siv tau txawm hais tias nws tus nqi ntau dua. Cov pheej yig tshaj tawm tau opics yuav txuag tau cov nyiaj uas pib, tab sis cov teeb meem uas txawv tsis pub dawb. Koj lub sijhawm muaj nuj nqis.

Ntsuam xyuas txhua yam ua ntej xa khoom. Cov hwj chim kho qhov muag, cov nqi yuam kev, kev ntsuas ceev. Tsis txhob xav tias nws ua haujlwm tsuas yog vim tias qhov txuas los.

Thiab tej zaum tseem ceeb tshaj: ports tshwj xeeb tsis yog kab laum, lawv yog ib qho tshwj xeeb. Modularity muab rau koj yooj kom phim cov hom fiber ntau, qhov deb, thiab kev ceev ceev rau txhua qhov kev sib txuas. Nws tsuas yog tias txoj kev kawm nkhaus yog steeper dua li ib tus neeg lees paub upfront.

Cov cuab yeej thev naus laus zis. Thaum koj nkag siab qhov koj tau hais txog, Fiber Optics yog kev ntseeg siab thiab nrawm thiab ua rau cov tes hauj lwm niaj hnub zoo dua li lwm yam. Tab sis hais tias "Thaum koj nkag siab"? Uas siv sij hawm, ua yuam kev, thiab tej zaum muaj qee hmo ntuj kawg ntawm Unit Portent wonde leds dab tsi koj tau ua txhaum.

Nws zoo. Txhua tus mus dhau nws.
