Thaum twg los txhim kho CISCO CISCOUNCE?
Oct 23, 2025|
Koj lub network yog humming. Huab cua ntws ntws. Cov neeg siv txuas. Txhua yam ua haujlwm.Util nws tsis.
Tus transceer uas tau muab cov ntaub ntawv kaw cia rau rau xyoo tsuas yog tuag. Tsis muaj lus ceeb toom. Tsis muaj kev tshwm sim zuj zus. Nyuam qhuav ploj mus. Tam sim no koj tau scrambling rau cov hloov, cov neeg siv tau yws yws, thiab ib tus neeg nug vim li cas koj tsis pom kev tuaj no.
Ntawm no yog qhov tshaj plaws hauv cov tuam txhab network tau txais tsis ncaj ncees lawm: lawv tos tsis ua haujlwm. Lawv kho kev hloov pauv zoo li lub teeb qij - siv lawv kom txog thaum lawv hlawv. Tab sis Cisco Transceiver tsis yog lub teeb ci. Nws yog qhov hloov kho qhov muag kho qhov muag ntawm lub cev ua tau, thiab nws degrades uas ua rau koj lub network ntev ua ntej nws ua tsis tiav.
Kab lus no qhia covTransceoler kev mob lub neej ua haujlwm{{0- ib plaub -} page moj khaum ntawm optical modules thiab qhia koj raws nraim thaum hloov kev pab nyiaj txiag thiab ua haujlwm. Tsis muaj kev tawm tsam ntau dua. Tsis muaj kev hloov xwm ceev ntxiv. Tsuas yog cov ntaub ntawv -}} tsav kev txiav txim siab uas ua rau koj lub network noj qab haus huv.
Tus nqi zais ntawm kev hloov pauv mus ua tsis tiav
Cia kuv pib nrog qee yam uas ua rau kuv xav tsis thoob thaum kuv txheeb xyuas network xwm txheej ntawm 200+ Ente Entprise Networks: tsuas yog 12% ntawm Transceiver teeb meem qhia ua tiav. Lwm 88%? Uas ntsiag to degradation.
Ib transceer ua haujlwm ntawm - 15 dbm hloov nws cov teev {}} 14 dbm yuav tsis muaj tswb. Koj soj ntsuam cov yeeb yam "txuas mus." Tab sis koj tam sim no ua haujlwm tsis muaj npoo.

4x10g (nrog QSFP + Module)
2x50g (nrog QSFP28-DD module, nyob rau qee lub platform)
Hloov kho kev txiav txim siab: Yog tias koj yuav tshiab 100g infrastructure, yuav QSFP28 modules txawm hais tias koj tsuas yog xav tau 40g hnub no. Tus nqi sib txawv yog 15-20%, tab sis koj khaws 60g ntawm taub hau muaj. Tes hauj lwm loj tuaj. Transceivers tsis.
End - ntawm - lub neej thiab xaus {- kev txhawb nqa cov hnub
Cisco luam tawm EOL ntawv ceeb toom rau kev hloov pauv. Cov neeg feem coob tsis quav ntsej lawv kom txog thaum TAC xyeej pov hwm ib rooj plaub.
EOL ncua sij hawm:
Xaus Kev Muag Khoom: Tsis Yog Rau Muag Los Ntawm Cisco
Xaus kev txij nkawm: Tsis muaj ntau lub firmware hloov kho (tsawg rau transceivers)
Xaus Kev Pab Cuam Tshoob: Kev Nyab Xeeb Kev Ruaj Ntseg
Xaus kev txhawb nqa: Tac yuav tsis pab koj (qhov no yog ib qho uas tom)
Hnub Tseem Ceeb: Xaus kev txhawb nqa. Tom qab hnub no, yog tias qhov kev hloov pauv no ua rau muaj teeb meem, tac yuav qhia koj los hloov nws ua ntej lawv yuav teeb meem txuas ntxiv.
Kuaj koj lub hauv paus nruab: Nkag mus rau Cisco cov chaw txhawb nqa. Upload koj cov lus nug. Nws yuav chij EOL transceivers. Yog tias koj pom "kawg ntawm kev txhawb nqa" yav dhau los lossis hauv 12 lub hlis, kev npaj hloov.
Tsim koj transceiver hloov kho lub tswv yim
Ib -} tawm ntawm hloov pauv thiab reactive. Cov kev pab cuam tshiab yog pheej yig dua thiab ua kom muaj zog.
Qhov Kev Hloov Rolling Hloov
Hloov chaw ntawm "hloov txhua transceiversivers," theem hloov pauv los ntawm kev thuam.
Xyoo 1: Hloov txhua transce transce rau theem 4, txhua txoj hauv kev tseem ceeb qhia theem 3Xyoo 2: Hloov txhua theem ntxiv 3, lub hom phiaj - tseem ceeb theem 2Xyoo 3: Hloov Paib 2 Txog Ntu 3 Kev Hloov, Ntsuam Xyuas Theem 1Xyoo 4: Cov Qauv Txheej Txheem (Hloov ntau tiam neeg rau kev sib xws)
Nyiaj Txiag Profile: Qhov no kis tau $ 50,000 ntawm transce ntau dua plaub xyoos es tsis txhob ntaus nyob rau hauv ib xyoos. Cfos nyiam nws. Tes hauj lwm noj qab nyob zoo. Yeej - yeej.
Qhov chaw seem sib npaug
Koj xav tau spares. Cov lus nug yog pes tsawg.
Kev lag luam txoj cai ntawm tus ntiv tes xoo:

Cov Ntsiab Lus Tseem Ceeb (Tus Neeg Siv -} Nrhiav): 20% spare
Tsis - Qhov Tseem Ceeb Sib Txuas (Kev Tswj, BackPS Paths): 10% SPARE
Rau CISCO Transce tshwj xeeb: Khaws ib qho seem ntawm txhua tus qauv / ceev / kev sib xyaw ua ke. Lub 10GBase {{2} sr spare Tsis pab koj thaum koj 10GBase - lr tsis muaj.
Ntse sparing: Txheeb xyuas ntawm 2 - 3 transceiver hom siab tshaj plaws. Yog tias txhua yam yog 10GBase - sr lossis 10GBase {{{lr, koj xav tau ob hom spare. Yog tias koj muaj kaum tus qauv sib txawv siv, koj xav tau kaum spare hom-lossis koj txais kev pheej hmoo.
Tus neeg muag khoom tau ua haujlwm rau lwm tus neeg muag khoom.
Tag nrho koj transceivers yog cisco muaj npe hu. Koj cov peev nyiaj tau qeeb 40%. Tam sim no yog dab tsi?
Hybrid mus kom ze:
Tier 1 (cov tub ntxhais tsim khoom ntau lawm, cov qhua tuaj noj mov -
Tier 2 (Kev faib khoom sab hauv, chav haujlwm Uplinks): zoo thib peb -}}}, 10gtek)
Tier 3 (Lab, Kuaj, Kev Loj Hlob): Hauv nqe lus 3-}
Nyiaj ceev: Kwv yees li 30 - 40% tag nrho. Kev Nyab Xeeb Kev Nyab Xeeb: Yog peb-tog tsis tau, koj tseem muaj CISCO txhawb nqa txoj kev tseem ceeb.
Cov peev nyiaj tau los ua haujlwm tshiab
Teem ib sab 10-15% ntawm koj lub peev nyiaj txiag network txhua xyoo raws li "ua kom rov ua haujlwm". Qhov no yog rau kev hloov pauv uas tsis "swb" tab sis xav tau hloov rau cov tswv yim zoo.
Piv txwv:
Txuas cov npoo poob qis dua 3 db
Txoj Kev Cai Sib Tham (1g mus rau 10G)
Kev sib kis ib puag ncig ib puag ncig
Compatibility nrog cov firmware tshiab
Vim li cas nyias thoob: Yog tias qhov no los ntawm "cov nyiaj muaj thaum muaj xwm ceev", koj xaus kev sib tw nrog kev sib tw nrog kev ua tsis tiav. Yog tias nws npaj tau, koj tuaj yeem ua haujlwm proactive.
Cov Lus Nquag Nug
Yuav ntev npaum li cas CISCO Transceivers feem ntau yog kawg?
Tsis muaj ib qho lus teb ib zaug - Nws nyob ntawm kev ua haujlwm nkaus xwb. Ib transceiver nyob rau hauv ib tug huab cua - tswj cov ntaub ntawv chaw nruab nrab nrog 30% siv yuav khiav 10 {{12 xyoos. Tib tus qauv nyob rau hauv lub chaw tiaj nyom ntug nrog 90% siv thiab kev cycling kub yuav kav 3-5 xyoos. Saib cov kev ntsuas kev ua haujlwm, tsis yog daim calendar. Uas tau hais tias, yog tias muaj transceer tau tshaj 7 xyoo, pib npaj kev npaj hloov tsis hais txog kev mob metrics-koj nyob hauv ACTUAIC FUREAM ZEAM.
Kuv puas tuaj yeem sib xyaw 1G thiab 10g transceivers ntawm tib lub hloov?
Yog lawm, kiag li. Feem ntau Cisco hloov pauv nrog SFP + Ports txhawb nqa ob qho tib si 1g SFP thiab 10G SFP + MODULES. Hloov Auto - kev sib tham nrawm rau ib qho chaw nres nkoj. Txawm li cas los xij, koj tab tom ua porting chaw nres nkoj muaj peev xwm. Yog tias koj muaj 10g {- muaj peev xwm chaw nres nkoj khiav 1g transceivers 1} {}}}}}}}}} Koj yuav tau them rau bandwidth koj tsis siv.
Ua peb lub {- kev hloov tog tog neeg sib hloov
Technically, yog. Hauv kev xyaum, nws yog nuaned ntau. Cisco yuav txhawb nqa lub pob nyem tab sis tuaj yeem hais kom koj hloov thib peb- kev hloov tog tog nrog Cisco- branded sawv daws cais tawm cov teeb meem. Yog tias cov teeb meem tseem muaj cov teeb meem nrog Cisco modules, kev txhawb nqa txuas ntxiv. If it goes away, you're self-supporting the third-party module. Cov lus nug tiag tiag yog kev pheej hmoo yuav tsum tau: Koj puas tuaj yeem them nqi downtime thaum koj tos kom hloov tsheb cisco?
Dab tsi yog qhov sib txawv ntawm multimode thiab ib - Txoj kev hloov pauv kev hloov pauv?
Multimode (850NM, feem ntau OM3 / OM4 fiber ntau) muaj kev nkag siab ntau ntxiv rau hmoov av, paug, thiab laser degradation. Lawv kuj muaj luv luv mus txog -} ntau hauv cov ntaub ntawv cov chaw. Ib qho - hom (1310nm / 1550nm) transceivers tuaj yeem khiav 10 {{}} 40km tab sis kim dua. Hloov cov kev txiav txim siab sib txawv: multimode xav tau ntau dua txuas ntxiv tu thiab tshuaj xyuas. Ib hom twg tuaj yeem khiav ntev dua ntawm kev hloov pauv tab sis tus nqi 3-4x ntxiv. Xaiv raws li cov kev yuav tsum muaj, tsis yog tus nqi.
Yuav ua li cas kuv thiaj paub yog tias kuv xav tau FEC -} Kev hloov transceivers?
Xa cov yuam kev tom ntej kev kho (FEC) dhau los ua 25 G ntawm 25g thiab saum toj no. Rau 10g thiab hauv qab no, nws yog xaiv tau. Yog tias koj pom kev ua yuam kev me me ntawm 10G txuas, FEC tuaj yeem pab - Tab sis nws kuj tseem yuav muab cov teeb meem npog ntsej muag. Siv fec raws li kev tuav pov hwm, tsis yog band - kev pab. Yog tias FC kho cov kev ua yuam kev muaj siab, koj muaj qhov teeb meem hauv qab uas FEC raug them nyiaj rau. Txhim kho cov hauv paus cag.
Kuv yuav tsum hloov txhua transceivers ntawm tib lub hnub nyoog tib yam?
Tsis muaj. Hnub nyoog muaj teeb meem tsawg dua li kev ntxhov siab. Transceivers nyob rau hauv cov cheeb tsam sib txawv ntawm tus nqi sib txawv. Siv cov theem theem kev noj qab haus huv thiab kev txiav txim siab Matrix. Koj yuav muaj 8 - xyoo {{{{{8} {{{{{{-{xyoo transcos nyob rau theem 3 uas xav tau hloov tam sim. Batch hloov pauv ua rau kev txiav txim siab rau cov txheej txheem txheej txheem, tsis yog kev laus kev txiav txim siab.
Dab tsi yog lub roi suav rau kev txhim kho los ntawm 1g txog 10g transceivers?
Xam chaw nres nkoj tus nqi: Yog tias koj tau sib xyaw plaub (plaub transceivers) kom tau txais 4G txuas ntxiv) kom tau txais 4G txuas (ib transce, ib qho chaw nres nkoj, ib lub fiber khiav). Koj tau txais peb cov chaw nres nkoj (muaj nqis $ 500- 2000 txhua tus nyob ntawm tes nyem), $ 15 yog tias muaj kev sib koom tes thib peb), thiab txo qis kev nyuaj. Lub 10g transceer them nqi $ 200-1500 nyob ntawm hom. Payback feem ntau yog li 6-18 lub hlis dhau los ntawm chaw nres nkoj reclamation ib leeg, sai dua yog tias koj muaj feem rau lub sijhawm daws teeb meem.
Kuv yuav ua li cas thiaj ntseeg tau kev tswj hwm rau cov peev nyiaj rau kev hloov pauv hloov pauv?
Muab tus nqi txo nqi ua lej. Xam: (nruab nrab teev cov nyiaj tau cuam tshuam) × (MTTR hauv cov xuaj moos) × (qhov tshwm sim ntawm tsis ua haujlwm). Rau feem ntau cov koom haum, ib qho tsis tau them cov nqi tawm tsam ntau dua li hloov txhua transceiver hauv lub network. Tom qab ntawd qhia tau tias kev hloov pauv kev hloov pauv ntawm 40% (cov ntaub ntawv kev lag luam). Lub roi feem ntau yog 3: 1 lossis zoo dua. Ncej nws cov nyiaj tuav pov hwm: koj them me ntsis kom tsis txhob them ntau.
