Isingeniso:I-ONU(Optical Network Unit) ihlukaniswe yaba iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi ye-passive optical,I-ONUiyisisetshenziswa esibulalayo somsebenzisi kunethiwekhi yokubona, ebekwe ekugcineni komsebenzisi, esetshenziswa nayoOLTukuze kuzuzwe I-Ethernet Layer 2, imisebenzi Yesendlalelo sesi-3, ukunikeza abasebenzisi ngezwi, idatha kanye namasevisi we-multimedia.
I-ONUIncazelo yenkomba yephaneli:
Ukukhanya kwamandla: Kuvaliwe okuluhlaza: Ukuhluleka kwamandla; Ukuvula Okuluhlaza: Vula amandla
Ukukhanya kwe-PON: Kukhanya okuluhlaza: kuvuliwe isikhathi eside kubonisa ukuthi ibhodi liphumelele ukuzihlola futhi imishini isebenza ngokujwayelekile.
Ukukhanya kwe-LOS: Kuvaliwe: Kujwayelekile
Jaja iphutha lomsebenzisi:
Iningi lamaphutha amaphutha omugqa we-fiber optical kanyeI-ONUamaphutha emishini. Okokuqala, hlola ukuthi inkomba yephaneli ijwayelekile yini. Uma kwenzeka ukwehluleka komugqa we-fiber optical, bheka isimo sokukhanya kwe-PON: uma ukukhanya kwe-PON kuluhlaza, kubonisa ukuthi umugqa we-fiber optical ujwayelekile, futhi uma ukukhanya kwe-PON kuvaliwe, kubonisa ukuthi umugqa we-fiber optical unqanyuliwe.
Hlola umugqa wefiber optical imitha yamandla optical. Ibanga elifanelekile lamandla okubona yila: 1490nm ububanzi: – 8dB ukuya – 28dB. Uma idlula ububanzi, izothinta ikhwalithi yokusebenza evamile yeI-ONUfuthi ukufinyelela ku-inthanethi komsebenzisi kuzothinteka. Hlola umugqa wefiber optical osezingeni eliphezulu bese uhlola intambo yomsila yesihlukanisi ehambisana nekhebuli yokubona yomsebenzisi engalungile ebhokisini lekhebula lokubona.
Ukuncishiswa kwe-2-way optical splitter ngu-3db
Ukuncishiswa kwe-4-way optical splitter ngu-6db
Ukuncishiswa kwe-splitter ye-8-way Optical ngu-9db
Ukuncishiswa kwesihlukanisi se-16-way Optical ngu-12db
Ukuncishiswa kwe-32-way optical splitter ngu-15db
Ukuncishiswa kwe-64-way optical splitter ngu-18db
1.Uma amandla okukhanya okukhiphayo we-pigtail ehlukanisiwe efanelekile, sicela ubeke esikhundleni se-fiber core phakathi kwebhokisi lokudlulisa ikhebula le-optical kanye nesakhiwo. Ngokuvamile, sibeka okungenani ama-fiber cores amabili esakhiweni, bese sihlola ekugcineni ngemva kokushintshwa. Uma kungumsila ovela kusihlukanisi futhi amandla ayo okukhanya efiber engafanelekile, sicela ubeke esikhundleni se-pigtail eyisipele, futhi usebenzise imitha yamandla okukhanya ukuze uhlole ofanelekayo ukuze uxhume ku-pigtail yokwakha.
2.Uma ulayini wefiber optical unephutha: qala ukhiphe i-pigtail ku-I-ONUukuhlola amandla okubona, uma kungekho ukukhanya noma amandla engafanelekile, sicela uye ku-flange yebhokisi lokudlulisa ikhebula ukuze uthole enye ye-1-32 ye-pigtails ye-optical splitter ehambisanaI-ONUUma i-pigtail ingafaneleki, ungashintsha noma iyiphi ye-pigtails eyi-1-32 engenzi lutho. Khumbula: i-fiber eyinhloko ye-optical splitter ayikwazi ukukhishwa, ezothinta bonkeI-ONU.
I-ONUIncazelo yenkomba yephaneli:
Isibani samandla: Isibani esiluhlaza sihlale sivuliwe: Amandla avuliwe; Cisha ukukhanya okuluhlaza: Cisha amandla
Ukukhanya kwe-LOS: KUVALIWE: Amandla optical atholiwe we-PON port ajwayelekile; Isibani esiluhlaza sihlala sivuliwe: Idivayisi itholakele futhi yabhaliswa; Ukucwayiza kokukhanya okuluhlaza: Idivayisi ayinayo idatha; Ukucwayiza: Imbobo ye-PON ayinakho ukukhanya noma amandla okubona aphansi kunokuzwela kokwamukela.
I-LAN1, LAN2, LAN3 kanye ne-LAN4 zonke ziyi-4RJ45 Port
I-FXS1 iyimbobo yezwi
Ukuxazulula inkinga: Okokuqala, hlola ukuthi ngabe i-I-ONUidivayisi isebenza ngokujwayelekile (ukuthi isibani senkomba kuphaneli yocingo sijwayelekile), bese uhlola ezinye izizathu ngemuva kokuthi ucingo lusebenze ngokujwayelekile. Inqubo iyafana nale engenhla.
Ukuze uthole ukuhlakanipha okwengeziweI-ONU/ ibhokisiI-ONU/ ukuxhumanaI-ONU/ i-fiber opticalI-ONU, ungathintana ngqo ne-HDV Phoelectron Technology LTD ukuze uthole imininingwane eyengeziwe. Inkampani yethu futhi inemikhiqizo yezokuxhumana yeOLT, I-Media Converter,Shintshakanye ne-SFP. Siyakwamukela ukubonisana.
Kusukela ekukhulumisaneni kwakho okukhaliphileI-ONUnomkhiqizi we-SFP.
