Isingeniso:I-ONU(Optical Network Unit) ihlukaniswe yaba amayunithi enethiwekhi yokubona asebenzayo kanye namayunithi enethiwekhi ye-passive optical network.I-ONUiyithuluzi lomsebenzisi kumanethiwekhi okukhanya, abekwe ekugcineni komsebenzisi, futhi asetshenziswe ngokuhlanganyelaOLTukuze kuzuzwe imisebenzi ye-Ethernet Layer 2 kanye Nesendlalelo sesi-3, ihlinzeka abasebenzisi ngezwi, idatha, namasevisi emidiya exubile.
Incazelo yeI-ONUIzinkomba zephaneli:
AMANDLA ukukhanya: kuvaliwe okuluhlaza: vala amandla: vula amandla
Ukukhanya kwe-PON: Kukhanya okuluhlaza: Ukukhanya okude kubonisa ukuthi ibhodi liphumelele ukuzihlola futhi idivayisi isebenza ngokujwayelekile
Isibani se-LOS: asivuliwe: isimo esivamile
Nquma amaphutha omsebenzisi:
Amaphutha ngokuyinhloko amaphutha e-optical path kanyeI-ONUamaphutha edivayisi. Okokuqala, hlola ukuthi ukukhanya kwenkomba yephaneli kujwayelekile yini. Hlola isimo sesibani se-PON ukuze uthole amaphutha endlela yokubona: isibani se-PON sivamise ukukhanyiswa ngokuluhlaza, okubonisa ukuthi indlela yokubona ivamile, futhi isibani se-PON sivaliwe, okubonisa ukuthi indlela yokubona iphukile.
Sebenzisa imitha yamandla okubona ukuze uhlole indlela yokubona. Ibanga elamukelekayo lamandla okubona lithi: 1490nm: – 8db ukuya – 28db. Uma ububanzi budlulwa, buzothinta ikhwalithi yokusebenza evamile ye-I-ONU, futhi ukufinyelela ku-inthanethi komsebenzisi kuzothinteka. Hlola indlela yokubona esezingeni eliphezulu, bese uya ebhokisini lokunikeza ikhebula lokubona ukuze uhlole intambo yomsila yesihlukanisi esihambisana nekhebuli yokubona yomsebenzisi engalungile.
Ukuncishiswa kwesihlukanisi sesiteshi esingu-1:2 ngu-3 db
1:4 ukuncishiswa kwesihlukanisi sesiteshi ngu-6db
Ukuncishiswa kwesihlukanisi sesiteshi esingu-1:8 ngu-9db,
1:16 ukuncishiswa kokuhlukaniswa kwesiteshi ngu-12db,
Ukuncishiswa kwesihlukanisi sesiteshi esingu-1:32 ngu-15 db,
Ukuncishiswa kwesihlukanisi sesiteshi esingu-1:64 ngu-18db,
I-1, Uma amandla okukhanya okukhiphayo we-pigtail ehlukanisiwe efanelekile, sicela ushintshe i-fiber core phakathi kwebhokisi lokuhlangana kwentambo ye-optical kanye nesakhiwo. Ngokuvamile, sizobeka okungenani ama-fiber cores amabili esakhiweni, bese siqhuba ukuhlolwa kokuphela ngemva kokushintshwa. Uma amandla okukhanya we-pigtail avela ku-splitter engafanelekile, sicela ubeke esikhundleni se-pigtail esele, futhi usebenzise imitha yamandla optical ukuhlola ofanelekayo ukuze uxhume ku-pigtail yokwakha.
Uma kuyiphutha lendlela yokubona: Okokuqala, khipha i-pigtail ku-I-ONUukuhlola amandla optical. Uma kungekho ukukhanya noma amandla engafanelekile, sicela uthole eyodwa ye-pigtails engu-1-32 ehambisanaI-ONUku-flange yebhokisi lokuhlangana kwekhebula elikhanyayo, bese ukhipha i-pigtail e-flange ukuze uhlole amandla okubona. Uma i-pigtail ingafaneleki, shintsha noma iyiphi ye-pigtails eyi-1-32 engenzi lutho. Khumbula ukuthi i-fiber eyinhloko ye-splitter ayikwazi ukukhishwa, okuzothinta bonkeI-ONUs.
I-ONUIncazelo yenkomba yephaneli yedivayisi Isibani samandla esiluhlaza sivuliwe unomphela: Amandla edivayisi avaliwe: Vala idivayisi isibani se-LOS: Valiwe: Imbobo ye-PON ithola amandla okukhanya avamile Isibani esiluhlaza sivuliwe unomphela: Idivayisi iqedela ukutholwa nokubhaliswa Ukucwayiza kwesibani esiluhlaza: Idivayisi ayenzi idatha Cha. ivuliwe: Imbobo ye-PON ayinakho ukukhanya noma amandla okubona aphansi kunokuzwela kokwamukela i-LAN1, i-LAN2, i-LAN3 LAN4 iyimbobo kagesi, i-FXS1 iyimbobo yezwi, nokuxazulula inkinga: Okokuqala, hlola ukuthiI-ONUidivayisi isebenza ngokujwayelekile (ukuthi ukukhanya okukhomba kuphaneli yocingo kujwayelekile). Ngemva kokuthi idivayisi isebenza ngokujwayelekile, thola ezinye izizathu. Inqubo iyafana naleyo echazwe ngenhla.
Ukuze uthole ukuhlakanipha okwengeziweI-ONUs/ibhokisiI-ONUs/ukuxhumanaI-ONUs/i-fiber opticalI-ONUs, sicela uthinte i-Shenzhen Haidwiwei Optoelectronic Technology Co., Ltd. ukuze uthole ulwazi oluningiliziwe. Inkampani yethu futhi inemikhiqizo yokuxhumana efana neOLTs, ama-transceivers, amaswishi, namamojula. Wamukelekile ukuza sizobonisana..
