Kugadzirisa Matambudziko uye Mhinduro dzeMatambudziko eOptical Module Transmission

Rudzi urwu rwekukanganisa runosanganisira zvakanyanyamaports asiri kuuya kuUP, maports anoratidza mamiriro eUP asi asiri kutumira kana kugamuchira mapaketi, zviitiko zve port up/down zvinowanzoitika, uye zvikanganiso zveCRC.
Chinyorwa chino chinoongorora nyaya idzi dzakajairika zvakadzama.

I. Chiteshi Hachiuyi Mudenga

Kutora10G SFP+/XFP ma modules e opticalSemuenzaniso, kana optical port ikatadza kubuda mushure mekunge yabatanidzwa nemumwe mudziyo, kugadzirisa matambudziko kunogona kuitwa kubva pazvinhu zvishanu zvinotevera:

Danho 1: Tarisa kana nzira dzekumhanya nedzeduplex dziri kumativi ese dzichienderana

Ita kutiratidza pfupiso yeinterfaceraira kuti uone mamiriro echiteshi.
Kana paine kusawirirana, gadzirisa speed yechiteshi uye duplex mode uchishandisakumhanyauyeduplexmirairo.

Danho rechipiri: Tarisa kana chiteshi chemudziyo nemodule ye optical zvichienderana ne speed uye duplex mode

Shandisaratidza pfupiso yeinterfaceraira kuti uone gadziriro yacho.
Kana paine kusawirirana, gadzirisa kumhanya kwakakodzera uye duplex mode uchishandisakumhanyauyeduplexmirairo.

Danho rechitatu: Tarisa kana madoko ese ari maviri ari kushanda nemazvo

Shandisa loopback test kuti uone kana maport ese ari maviri achigona kukwira.

• On 10G SFP+ madokoPakadhi remagetsi, shandisa tambo ye10G SFP+ yakabatana zvakananga (yekubatanidza zviri kure) kana mamodule eSFP+ optical ane tambo dzefiber patch.

• On Madhoo e10G XFP, shandisai XFP optical modules uye optical fiber pakuedza.

Kana chiteshi chikasvika UP, chiteshi chepeer hachina kujairika.
Kana chiteshi chikasakwira, chiteshi chemuno hachina kujairika.
Dambudziko rinogona kusimbiswa nekutsiva nzvimbo yemuno kana yekambani.

Danho rechina: Tarisa kana optical module iri kushanda nemazvo

Tarisa zvakanyanyaRuzivo rweDDM, simba rekuona, kureba kwewavelength, uye daro rekutumirwa.

• Ruzivo rweDDM
  Shandisaratidza ruzivo rwe transceiver ye interfacesraira kuti utarise kana ma parameter ari akajairwa.
  Kana maaramu akaonekwa, module ye optical inogona kunge isina kunaka kana kuti isingaenderane nerudzi rwe optical interface.

• Simba reOptical
  Shandisa chiyereso chemagetsi che optical kuti uedze kana mazinga emagetsi e optical anotumirwa uye anogamuchira akagadzikana uye ari mukati mehuwandu hwakajairika.

• Kureba kweWave / Kureba
  Shandisaratidza chiratidziro chetransceiverkuraira kuti uone kana kureba kwewavelength uye daro rekutumirwa kwema optical modules kumativi ese ari maviri zvakafanana.

Danho rechi5: Tarisa kana fiber ye optical iri yakajairika

Semuyenzaniso:

• Mamodule eSFP+ optical emodhi imwe chete anofanira kushandiswa nefiber yemodhi imwe chete.

• Multimode SFP+ optical modules dzinofanira kushandiswa ne multimode fiber.

Kana paine kusawirirana, chinja faibha nerudzi rwakakodzera nekukasika.

Kana dambudziko risingawanikwe mushure mekupedza zvese zvataurwa pamusoro apa, zvinokurudzirwa kubata vashandi verutsigiro rwehunyanzvi hwemutengesi kuti vabatsirwe.

II. Chimiro chePort chiri kumusoro asi hachisi kutumira kana kugamuchira mapaketi

Kana mamiriro echiteshi ari UP asi mapaketi asingakwanise kutumirwa kana kugamuchirwa, gadzirisa matambudziko kubva pazvinhu zvitatu zvinotevera:

Danho 1: Tarisa nhamba dzepaketi

Tarisa kana mamiriro echiteshi kumativi ese ari maviri achiramba ari UP uye kana ma "packet counter" kumativi ese ari kuwedzera.

Danho rechipiri: Tarisa kana gadziriro yechiteshi ichikanganisa kutapurirana kwepaketi

• Kutanga, tarisa kana paine magadzirirwo enetwork akashandiswa uye tarisa kana akarurama. Kana zvichidikanwa, bvisa magadzirirwo ese woedza zvakare.

• Chechipiri, tarisa kana kukosha kwechiteshi cheMTU kuri1500Kana MTU yakakura kupfuura 1500, gadzirisa magadzirirwo acho zvinoenderana.

Danho rechitatu: Tarisa kana chiteshi chekubatanidza nepakati pekubatanidza zviri zvakajairika

Tsiva chiteshi chakabatana wochibatanidza kune chimwe chiteshi kuti uone kana dambudziko rakafanana richiitika.
Kana dambudziko rikaramba riripo, chinja optical module.

Kana dambudziko racho risingagone kugadziriswa mushure mekuongorora kwataurwa pamusoro apa, zvinokurudzirwa kubata vashandi verutsigiro rwehunyanzvi hwemutengesi.

III. Chiteshi Chinowanzokwira Kumusoro Kana Kudzika

Kana chiteshi che optical chichiwanzokwira kana kudzika:

• Kutanga, simbisa kana optical module isina kunaka nekutarisa kutiruzivo rwearamu, uye kugadzirisa matambudziko ese ari maviri ma optical modules pamwe ne connecting fiber.

• Kune ma module e optical anotsigirakuongorora kuongororwa kwedhijitari, tarisa ruzivo rweDDM kuti uone kana simba reoptical riri padanho rakakosha.

  • Kanatumira simba remazisoKana iri pamutengo wakakosha, tsiva optical fiber kana optical module kuti usimbise cross-proof.

  • Kanagamuchira simba rekuonairi pamutengo wakakosha, gadzirisa dambudziko re peer optical module uye connecting fiber.

Kana dambudziko iri rikaitika nemamodule emagetsi emagetsi, edza kugadzirisa speed yechiteshi uye duplex mode.

Kana dambudziko rikaramba riripo mushure mekutarisa chinongedzo, zvishandiso zve peer, uye michina yepakati, zvinokurudzirwa kubata vashandi verutsigiro rwehunyanzvi hwemutengesi.

IV. Zvikanganiso zveCRC

Danho 1: Tarisa nhamba dzepaketi kuti uone dambudziko racho

Shandisaratidza chimiroraira kuti utarise nhamba dzepaketi yekukanganisa munzira dzese dziri mbiri dzekupinda nedzekubuda uye uone kuti ndeapi macounter ari kuwedzera.

• Zvikanganiso zveCEC, furemu, kana throttle zvinowedzera pakupinda

  • Shandisai zvishandiso zvekuyedza kuti muone kana chinongedzo chacho chisina kunaka. Kana zvakadaro, chinjai tambo ye network kana optical fiber.

  • Neimwe nzira, batanidza tambo kana optical module kune imwe port.

    • Kana zvikanganiso zvikaonekwazve mushure mekuchinja maports, chiteshi chekutanga chingave chisina kunaka.

    • Kana zvikanganiso zvichiri kuitika pachiteshi chinozivikanwa, dambudziko ringangodaro riri pamudziyo wepeer kana kuti intermediate transmission link.

• Zvikanganiso zvekudarika zvichiwedzera pakupinda
  Mhanyaratidza chimiroraira kakawanda kuti uone kanazvikanganiso zvekuisazviri kuwedzera.
  Kana zvakadaro, izvi zvinoratidza kuwedzera kwehuwandu hwezvinhu zvinodarika mwero, zvichida zvichikonzerwa nekuzara kwemukati kana kuvharika kwekadhi remutsara.

• Zvikanganiso zvemahombe zviri kuwedzera pakupinda
  Tarisa kana magadzirirwo efuremu huru kumativi ese ari maviri akafanana, kusanganisira:

  • Hurefu hwepaketi hwakatarwa

  • Hurefu hwakanyanya hwepaketi hunobvumidzwa

Danho rechipiri: Tarisa kana simba re optical module rakajairika

Shandisaratidza ruzivo rwe transceiver interfaceskuraira kuti utarise kukosha kwekuongorora kwedhijitari kuripo kwemodule ye optical yakaiswa.
Kana simba remagetsi risina kujairika, chinja module yemagetsi.

Danho rechitatu: Tarisa kana gadziriro yechiteshi yakajairika

Shandisaratidza pfupiso yeinterfacemurairo wekusimbisa marongero echiteshi, uchitarisa pane:

• Mamiriro ekutaurirana

• Duplex mode

• Kumhanya kwechiteshi

Kana pakawanikwa nzira yehafu-duplex kana kusawirirana kwespeed, gadzirisa nzira chaiyo ye duplex uye port speed uchishandisaduplexuyekumhanyamirairo.

Danho rechina: Tarisa kana chiteshi chekufambisa negedhi remagetsi zviri zvakajairika

Tsiva chiteshi chakabatana kuti uone kana dambudziko richiripo.
Kana zvikadaro, tarisa zvishandiso zvepakati uye nzira dzekutumira data.
Kana zviri zvakajairika, tsiva optical module.

Danho rechishanu: Tarisa kana chiteshi chiri kugamuchira huwandu hwakawanda hwemafuremu ekudzora kuyerera

Shandisaratidza chimiromurairo wekutarisafuremu yekumbomirakaunda.
Kana kaunda ikaramba ichikwira, chiteshi chiri kutumira kana kugamuchira huwandu hwakawanda hwemafuremu ekudzora kuyerera kwemvura.

Tarisawo kana vanhu vakawanda vari kupinda nekubuda uye kana mudziyo wepeer une mukana wakakwana wekugadzirisa vanhu vari kufamba.

Kana pasina matambudziko anowanikwa ne configuration, peer devices, kana transmission link mushure mekupedza kuongorora kwese, ndapota taura nechikwata chekutsigira tekinoroji chemutengesi zvakananga.
