Intshayelelo:I-ONU(Iyunithi yeNethiwekhi yeOptical) yahlulwe yaba ziiyunithi zothungelwano olusebenzayo kunye neeyunithi zothungelwano lwe-passive optical network.I-ONUsisixhobo somsebenzisi kwiinethiwekhi zamehlo, ezibekwe ekupheleni komsebenzisi, kwaye zisetyenziswe ngokudibeneyoOLTukufezekisa i-Ethernet Layer 2 kunye nemisebenzi ye-Layer 3, ukubonelela abasebenzisi ngelizwi, idatha, kunye neenkonzo zemultimedia.
Inkcazelo yeI-ONUizalathisi zephaneli:
AMANDLA isibane: cima luhlaza: cima amandla: vula amandla
Ukukhanya kwe-PON: Kulayitiwe luhlaza: Ukuvula ixesha elide kubonisa ukuba ibhodi iluphumelele uvavanyo lobuqu kwaye isixhobo sisebenza ngokwesiqhelo
Isibane se-LOS: asikhanyisi: imeko eqhelekileyo
Qinisekisa iimpazamo zabasebenzisi:
Iziphene ziziimpazamo zendlela ye-optical kwayeI-ONUiimpazamo zesixhobo. Okokuqala, khangela ukuba ukukhanya kwesalathisi sepaneli kuqhelekileyo. Khangela isibane sesibane se-PON kwiimpazamo zendlela ye-optical: isibane se-PON sivame ukulayita eluhlaza, ebonisa ukuba indlela ye-optical iyinto eqhelekileyo, kwaye isibane se-PON sivaliwe, esibonisa ukuba indlela yokubona iphukile.
Sebenzisa imitha yamandla okukhanya ukuvavanya indlela yamehlo. Uluhlu olwamkelekileyo lwamandla okukhanya lu: 1490nm: – 8db ukuya – 28db. Ukuba uluhlu lugqithisiwe, luya kuchaphazela umgangatho oqhelekileyo wokusebenza weI-ONU, kwaye ukufikelela kwe-intanethi komsebenzisi kuya kuchaphazeleka. Jonga umgangatho ophezulu wendlela yokubona, kwaye uye kwibhokisi yonikezelo yentambo yokukhanya ukuvavanya ifayibha yomsila wesahlukanisi esihambelana nentambo yokukhanya yomsebenzisi engalunganga.
Ukuqwalaselwa kwe-1:2 i-channel splitter yi-3 db
I-1:4 i-channel splitter attenuation yi-6db
Ukuthotywa kwe-1:8 i-channel splitter yi-9db,
1:16 ukuthotywa kwejelo lokwahlulahlula yi-12db,
Ukuthotywa kwe-1:32 isiqhekeza isitishi yi-15 db,
Ukuthotywa kwe-1:64 isiqhekeza setshaneli yi-18db,
I-1, Ukuba imveliso ye-optical power ye-pigtail ye-splitter ifanelekile, nceda ubuyisele i-fiber core phakathi kwebhokisi ye-optical cable junction kunye nesakhiwo. Ngokubanzi, siya kubeka ubuncinci ii-fiber cores kwisakhiwo, kwaye emva koko siqhube uvavanyo lokugqibela emva kokutshintshwa. Ukuba amandla okukhanya kwe-pigtail evela kwi-splitter ayifanelekanga, nceda utshintshe i-pigtail eseleyo, kwaye usebenzise imitha yamandla okukhanya ukuvavanya umntu ofanelekileyo ukudibanisa kwi-pigtail yokwakha.
Ukuba yimpazamo yendlela yokukhanya: Okokuqala, khulula i-pigtail kwiI-ONUukuvavanya amandla optical. Ukuba akukho kukhanya okanye amandla akafanelekanga, nceda ufumane enye ye-1-32 pigtails ehambelana neI-ONUkwi-flange yebhokisi ye-optical cable junction, kwaye ukhuphe i-pigtail kwi-flange ukuvavanya amandla optical. Ukuba i-pigtail ayifanelekanga, buyisela nayiphi na enye ye-1-32 ye-pigtails engasebenziyo. Khumbula ukuba i-fiber ephambili ye-splitter ayikwazi ukukhutshwa, eya kuchaphazela bonkeI-ONUs.
I-ONUIsixhobo sepaneli yesalathisi Inkcazo yokukhanya Isibane esiluhlaza ngokusisigxina: Amandla esixhobo Cinyiwe: Cima isixhobo sicinywa isibane se-LOS: Cimile: Izibuko le-PON lifumana amandla okukhanya aqhelekileyo Isibane esiluhlaza ngokusisigxina: Isixhobo sigqibezela ukufunyanwa kunye nokubhaliswa Ukukhanya okuluhlaza okudanyazayo: Isixhobo asenzi idatha Hayi. kwi: Izibuko lePON alinakukhanya okanye amandla okubona asezantsi kunovakalelo lolwamkelo LAN1, LAN2, LAN3 LAN4 lizibuko lombane, iFXS1 lizibuko lelizwi, kunye nolungiso lweengxaki: Kuqala, khangela ukubaI-ONUisixhobo sisebenza ngesiqhelo (nokuba isibane sokukhanya kwiphaneli yesixhobo siqhelekile). Emva kokuba isixhobo sisebenza ngokuqhelekileyo, fumana ezinye izizathu. Inkqubo iyafana nale ichazwe ngasentla.
