Izinzuzo kanye Nobubi be-XGPON ne-GPON

I-XGPON ne-GPON ngayinye inezinzuzo zayo kanye nokubi futhi ifanele izimo ezihlukene zohlelo lokusebenza.

Izinzuzo ze-XGPON zifaka:

I-1.Izinga lokudlulisela eliphezulu: I-XGPON inikeza kufika ku-10 Gbps i-downlink bandwidth kanye ne-2.5 Gbps uplink bandwidth, ifanele izimo zohlelo lokusebenza ezinesidingo esikhulu sokudluliswa kwedatha ngesivinini esikhulu.

I-2.Ubuchwepheshe bokushintshashintsha obuthuthukisiwe: I-XGPON isebenzisa ubuchwepheshe obuthuthukisiwe bokuguquguquka obufana ne-QAM-128 ne-QPSK ukuthuthukisa ikhwalithi nebanga lokudluliswa kwesignali.

3.Inethiwekhi ebanzi: Isilinganiso sokuhlukanisa se-XGPON singafinyelela ku-1:128 noma ngaphezulu, siyivumele ukuthi ihlanganise indawo ebanzi yenethiwekhi.

Kodwa-ke, i-XGPON nayo inokungalungi okuthile:

1.Izindleko eziphakeme: Ngenxa yokuthi i-XGPON isebenzisa ubuchwepheshe obuthuthukisiwe kanye nezisetshenziswa zamafrikhwensi aphezulu, izindleko zayo ziphakeme futhi zingase zingalungeli izimo zohlelo lokusebenza ezingazweli kakhulu.

Izinzuzo zeI-GPONikakhulukazi zihlanganisa:

1.Isivinini esikhulu kanye nomkhawulokudonsa ophezulu:I-GPON inganikeza amazinga okudlulisela angu-1.25 Gbps (indlela eya phansi komfula) kanye no-2.5 ​​Gbps (inkomba yomfula) ukuze ihlangabezane nezidingo zabasebenzisi zokuxhuma i-broadband enesivinini esikhulu.

2.Ibanga elide lokudlulisela:Ukudluliswa kwe-fiber optical kuvumela amabanga okudlulisa isignali ukuthi afinyelele amashumi amakhilomitha, ahlangabezane nezidingo eziningi ze-network topology.

3.Ukudluliselwa kwe-Symmetric ne-asymmetric:I-GPON isekela ukudluliswa kwe-symmetric kanye ne-asymmetric, okungukuthi, amazinga okudlulisa i-uplink ne-downlink angahluka, okuvumela inethiwekhi ukuthi ivumelane kangcono nezidingo zabasebenzisi abahlukene kanye nezinhlelo zokusebenza.

4.I-architecture esabalalisiwe:I-GPON isebenzisa i-point-to-multipoint optical fiber transmission architecture futhi ixhuma amatheminali olayini obonakalayo (OLT) kanye namayunithi enethiwekhi amaningi optical (ONUs) ngomugqa owodwa wefiber optical, ukuthuthukisa ukusetshenziswa kwezinsiza zenethiwekhi.

5.Isamba sentengo yesisetshenziswa siphansi:Njengoba izinga le-uplink liphansi uma kuqhathaniswa, izindleko zezingxenye zokuthumela ze-ONU (njengama-lasers) nazo ziphansi, ngakho-ke inani lentengo yezinto zokusebenza liphansi.

Ububi be-GPON ukuthi ihamba kancane kune-XGPON futhi ingase ingafaneleki izimo zohlelo ezidinga ukudluliswa kwedatha okunesivinini esikhulu.

Kafushane, i-XGPON ne-GPON ngayinye inezinzuzo zayo kanye nokubi futhi ifanele izimo ezihlukene zohlelo lokusebenza. I-XGPON ifanele izimo zohlelo lokusebenza ezinesidingo esikhulu sokudluliswa kwedatha ngesivinini esikhulu, njengamabhizinisi amakhulu, izikhungo zedatha, njll.; kuyilapho i-GPON ifaneleka kakhulu kuzimo zokufinyelela eziyisisekelo zamanethiwekhi asekhaya nawebhizinisi ukuhlangabezana nezidingo zenethiwekhi zansuku zonke. Lapho kukhethwa ubuchwepheshe benethiwekhi, izici ezifana nesidingo, izindleko, nezimfuneko zobuchwepheshe kufanele zicatshangelwe.
