Isingeniso: I-ONU (Optical Network Unit) ihlukaniswe yaba iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi ye-passive optical, i-ONU iyisisetshenziswa esibulalayo somsebenzisi kunethiwekhi ye-optical, ebekwe ekugcineni komsebenzisi, esetshenziswa ne-OLT ukuze kuzuzwe i-Ethernet Layer 2, imisebenzi ye-Layer 3. , ukuhlinzeka abasebenzisi ngezwi, idatha kanye namasevisi we-multimedia.
Incazelo yephaneli ye-ONU:
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 e-optical fiber line kanye namaphutha emishini ye-ONU.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 evamile yokusebenza ye-ONU futhi 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 umugqa we-fiber optical unephutha: qala ukhiphe i-pigtail ku-ONU ukuze uhlole amandla okukhanya, uma kungekho ukukhanya noma amandla engafaneleki, sicela uye ku-flange yebhokisi lokudlulisa ikhebula ukuze uthole eyodwa i-pigtails engu-1-32 ye-splitter ye-optical ehambisana ne-ONUKhumbula: i-fiber eyinhloko ye-optical splitter ayikwazi ukukhishwa, ezothinta yonke i-ONU.
Incazelo yephaneli ye-ONU:
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 idivayisi ye-ONU isebenza ngokujwayelekile yini (ukuthi ukukhanya okukhomba kuphaneli yedivayisi kujwayelekile), bese uhlola ezinye izizathu ngemuva kokuthi idivayisi isebenza ngokujwayelekile.Inqubo iyafana nale engenhla.
Ukuze uthole ukuhlakanipha okwengeziwe kwe-ONU / ibhokisi le-ONU / ukuxhumana kwe-ONU / i-fiber optical ONU, ungaxhumana ngokuqondile ne-HDV Phoelectron Technology LTD ukuze uthole imininingwane eyengeziwe.Inkampani yethu futhi inemikhiqizo yokuxhumana ye-OLT, Media Converter, Switch kanye ne-SFP.Siyakwamukela ukubonisana.
Kusukela kumkhiqizi wakho we-ONU&SFP wokuxhumana ohlakaniphile.
