Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Izinhlobo Zezintambo Ze-MTP/MPO
Izintambo ze-MTP/MPO zokuxhumeka kwe-switch-to-switch zivame ukulinganiselwa ku-plenum ukuze zisetshenziswe ngaphakathi futhi zitholakala kokubili ku-singlemode (OS2) kanye nezinhlobo ze-multimode fiber (OM3, OM4, OM5). I-OM4 iyisinqumo esivame kakhulu kuzinhlelo zokusebenza ze-multimode ngenxa yokubambezeleka kwayo okuncishisiwe kwemodi yokuhlukanisa, okusekela amabanga amade. I-OM5 fiber ilungiselelwe i-short wavelength division multiplexing (SWDM), okuvumela ama-wavelength amaningi ukuthi adlulisele idatha ngesikhathi esisodwa ukuze kufinyeleleke isikhathi eside.
Lezi zintambo ziza ngobude obujwayelekile noma obungokwezifiso futhi zisukela kumafayibha angu-8 kuya kwangu-144, ziphela ngezixhumi ze-MTP/MPO ezingu-8, 12, 16, noma ezingu-24. Izintambo ezine-fiber ephezulu zinezixhumi eziningi ngaphansi kwe-sheath eyodwa—isibonelo, ikhebula le-fiber engu-72 livame ukuba nezixhumi eziyisithupha ze-fiber ezingu-12 ekugcineni ngakunye. Izixhumi ezintsha ezincane kakhulu ze-form factor (VSFF), njengesixhumi se-US Conec's MMC 16-fiber, zinikeza ukuminyana kwe-port okuphindwe kathathu ngenxa yobukhulu bazo obuncane.
Izintambo ze-MTP/MPO zingalungiswa njengezintambo ze-trunk ezinezixhumi ezifanayo kuzo zombili izinhlangothi noma njengezintambo ze-breakout (fan-out) zokuxhuma ama-port anesivinini esikhulu kumadivayisi amaningi anesivinini esiphansi. Ngenkathi izintambo ze-breakout zivame ukushintsha kusuka ku-MTP/MPO ziye ku-duplex connectors kumaseva angu-25, 50, noma angu-100 Gig, zingasekela nezixhumanisi ze-switch-to-switch—isibonelo, ukuphula isixhumi se-fiber esingu-16 noma esingu-24 sibe izixhumi eziningi ze-MTP/MPO ezine-fiber engu-8 noma engu-12 ukuze kusetshenziswe kahle i-port.
Indlela Yokukhetha Ikhebula Elifanele Le-MTP/MPO
Ukukhethwa kwezintambo ze-MTP/MPO zokuxhumeka kwe-switch-to-switch kuqhutshwa kakhulu yizidingo ezithile zohlelo lokusebenza, ezithonywa yizici ezifana nesivinini sokudlulisa, ibanga phakathi kwama-switch, izindleko, kanye nobuningi be-port.
Zombili izintambo zefayibha ze-multimode kanye ne-singlemode zisekela isivinini sama-200, 400, kanye nama-800 Gig, kodwa ukufinyelela kuyahlukahluka kakhulu. Ifayibha ye-Multimode ivame ukukhawulelwa kumamitha ayi-100 ukuze kuxhunywe izixhumanisi zesivinini esikhulu, okwenza ifaneleke kakhulu ekuxhumaneni kwesikhungo sedatha yangaphakathi. Ifayibha ye-Singlemode isekela amabanga afinyelela kumakhilomitha angama-40, okubalulekile ezikhungweni zedatha ezinkulu zamafu noma ze-hyperscale lapho izixhumanisi zingadlula amamitha ayi-100. Izindleko nazo zidlala indima ebalulekile; izinhlelo zokusebenza ze-singlemode ezifinyelela isikhathi eside zivame ukudinga ama-WDM optics angabiza ngokuphindwe kahlanu kunemishini ye-multimode. Ngamabanga adlula amamitha ayi-100, izinhlelo zokusebenza ze-DR singlemode ezifinyelela isikhathi esifushane zinikeza enye indlela engabizi kakhulu esebenzisa ama-laser asebenzisa amandla kahle, kuyilapho izinhlelo zokusebenza ze-VR multimode ezifinyelela isikhathi esifushane zihlala ziyisinqumo esingabizi kakhulu sezixhumanisi ezingaphansi kwamamitha angama-50.
Inani lefayibha kanye nohlobo lwesixhumi kuyahlukahluka ngohlelo lokusebenza. Isibonelo, izixhumanisi ezingu-200 no-400 Gig SR4, VR4, kanye ne-DR4 zisebenzisa izixhumi ze-MTP/MPO ezingu-8-fiber ezinezintambo ezine zokudlulisa kanye nezine zokwamukela ku-50 noma 100 Gb/s ngomzila ngamunye. Ngokuphambene nalokho, izinhlelo zokusebenza ezingu-800 Gig SR8, VR8, kanye ne-DR8 zidinga izintambo ezingu-16—eziyisishiyagalombili zokudlulisa kanye neziyisishiyagalombili zokwamukela ku-100 Gb/s ngomzila ngamunye—ezingasekelwa izixhumi ezimbili ze-fiber ezingu-8, isixhumi esisodwa se-MTP/MPO esingu-16-fiber, noma isixhumi se-VSFF MMC esingu-16-fiber. Isixhumanisi sesixhumi kumele sihambisane ne-switch port noma iphaneli ye-patch, kanye nezixhumi ze-VSFF ezifana ne-MMC ezinikeza ukuminyana okuphezulu ezindaweni ezivinjelwe isikhala. Ithebula elingezansi lifingqa izinhlelo zokusebenza zakamuva ze-multimode kanye ne-singlemode zezixhumanisi ze-200, 400, kanye ne-800 Gig switch-to-switch ezisebenzisa izintambo ze-MTP/MPO.

Ezinye Izinto Ezibalulekile Okufanele Uzicabangele
Ezinye izinto okufanele uzicabangele lapho ukhetha izintambo ze-MTP/MPO zifaka phakathi ukucushwa kwe-breakout kanye nezinhlobo zokuphela kwesixhumi. Izinhlelo zokusebenza ze-breakout, njenge-2X100G, 4X100G, 2X200G, noma i-2X400G, zidinga imiklamo ethile yekhebula. Isibonelo, ikhebula le-breakout le-4X100G livame ukuba nesixhumi se-8-fiber MTP/MPO kolunye uhlangothi kanye nezixhumi ezine ze-duplex kolunye. Ezindaweni ze-HPC ezifana namaqoqo e-AI, izinhlelo zokusebenza ze-breakout ze-2X400G zivamile, kusetshenziswa isixhumi se-16-fiber MTP/MPO esiqhekeka sibe izixhumi ezimbili ze-8-fiber MTP/MPO.
Uhlobo lwesiphetho sesixhumi luyisici esibalulekile. Izixhumi ze-UPC (ezisicaba) ziyindinganiso yezinhlelo zokusebenza ze-multimode, kuyilapho izixhumi ze-APC (ezine-angled) zidingeka kwimodi eyodwa ngenxa yokukhanya kwazo okuphansi, okubalulekile ekunciphiseni ukulahleka kwesignali. Iziphetho ze-APC nazo ziyanconywa kakhulu kwizixhumanisi ze-multimode ezinesivinini esikhulu ku-400G kanye no-800G. Kubalulekile ukufanisa uhlobo lwesiphetho—i-UPC noma i-APC—nengxenye yokuhlangana, njengoba ukuxuba lokhu okubili kungabangela ukuwohloka kwesignali kanye nomonakalo ongaba khona ezixhumini.
Njengoba izixhumanisi zokushintshela ku-switch zakha umgogodla wemisebenzi yesikhungo sedatha, ukusebenza kanye nekhwalithi kubaluleke kakhulu. Ukuze wandise isikhathi sokusebenza kanye nokuthembeka, khetha kuphela izintambo ze-MTP/MPO ezakhiwe nge-fiber esezingeni eliphezulu, izingxenye ze-optical ezinembile, kanye nokusebenza kokulahlekelwa kokufakwa okuqinisekisiwe.
I-KEXINT ingumhlinzeki ohamba phambili wezintambo ze-multimode kanye ne-singlemode MTP/MPO, enikeza ubude obukhethekile kanye nokulungiselelwa okulungiselelwe ukuxhumana kwakho kwe-data center switch-to-switch. Ikhebula ngalinye lakhiwe ngezingxenye zokunemba zesimanje futhi lisekelwa ukuzibophezela kwethu okungaguquki kwikhwalithi. Xhumana nathi namuhla ukuze uthole zonke izidingo zakho zokuxhuma izintambo ze-MTP/MPO.
