1. Menene XGS-PON?
DukaXG-PONkuma XGS-PON na cikinGPONjerin.Daga taswirar fasaha, XGS-PON shine juyin fasaha na XG-PON.
Dukansu XG-PON da XGS-PON sune 10G PON, babban bambanci shine: XG-PON shine PON asymmetric, ƙimar haɓakawa / saukar da tashar PON shine 2.5G/10G;XGS-PON PON mai ma'auni ne, ƙimar haɓakawa / saukar da tashar PON Adadin shine 10G/10G.
Babban fasahar PON da ake amfani da su a halin yanzu sune GPON da XG-PON, dukkansu PON asymmetrical ne.Tunda bayanan sama/sauka na mai amfani gabaɗaya asymmetrical ne, ɗaukar wani birni na farko a matsayin misali, matsakaicin zirga-zirgar sama na OLT shine kawai 22% na zirga-zirgar ƙasa.Don haka, halayen fasaha na asymmetric PON suna da alaƙa da buƙatun masu amfani.wasa.Mafi mahimmanci, ƙimar haɓakawa na asymmetric PON yayi ƙasa, farashin aika abubuwan da aka gyara kamar lasers a cikin ONU yayi ƙasa, kuma farashin kayan aiki yayi ƙasa daidai.

2. Kasancewar XGS-PON, XG-PON da GPON
XGS-PON shine juyin fasaha na GPON da XG-PON, kuma yana goyan bayan gauraye damar nau'ikan ONU guda uku: GPON, XG-PON da XGS-PON.
2.1 Kasancewar XGS-PON da XG-PON
Kamar XG-PON, hanyar saukar da XGS-PON tana ɗaukar hanyar watsa shirye-shirye, kuma haɗin kai yana ɗaukar hanyar TDMA.
Tun da ƙananan raƙuman raƙuman ruwa da ƙananan raƙuman ruwa na XGS-PON da XG-PON iri ɗaya ne, ƙananan XGS-PON ba ya bambanta tsakanin XGS-PON ONU da XG-PON ONU, kuma mai rarraba na gani yana watsa siginar gani na ƙasa zuwa ga hanyar haɗin ODN iri ɗaya Ga kowane XG (S) -PON (XG-PON da XGS-PON) ONU, kowane ONU ya zaɓi karɓar siginar kansa kuma yana watsar da sauran sigina.
Haɗin kai na XGS-PON yana aiwatar da watsa bayanai gwargwadon ramukan lokaci, kuma ONU yana aika bayanai a cikin ramukan lokacin da OLT ya ba da izini.OLT yana ba da ramukan lokaci gwargwadon buƙatun zirga-zirga na ONU daban-daban da nau'in ONU (shin XG-PON ne ko XGS-PON?).A cikin lokacin da aka ware wa XG-PON ONU, yawan watsa bayanai shine 2.5Gbps;a cikin lokacin da aka ware wa XGS-PON ONU, yawan watsa bayanai shine 10Gbps.
Ana iya ganin cewa XGS-PON a zahiri yana goyan bayan gauraye damar shiga tare da nau'ikan ONU guda biyu, XG-PON da XGS-PON.
2.2 Zaman tare na XGS-PON daGPON
Tun da tsayin raƙuman sama / ƙasa ya bambanta da na GPON, XGS-PON yana amfani da maganin Combo don raba ODN tare da GPON.Don ka'idar maganin Combo, koma zuwa labarin "Tattaunawa akan Magani don Inganta Amfani da Albarkatun XG-PON na Hukumar Masu Biyan Haɗin Haɗin".
Combo Optical Module na XGS-PON ya haɗa GPON na gani na gani, XGS-PON na gani na gani da WDM multiplexer.
A cikin jagorar sama, bayan siginar gani ta shiga tashar jiragen ruwa ta XGS-PON Combo, WDM tana tace siginar GPON da siginar XGS-PON gwargwadon tsayin raƙuman ruwa, sannan aika siginar zuwa tashoshi daban-daban.
A cikin hanyar da ke ƙasa, siginar daga tashar GPON da tashar XGS-PON suna da yawa ta hanyar WDM, kuma siginar da aka haɗe yana raguwa zuwa ONU ta hanyar ODN.Tun da tsayin raƙuman ruwa ya bambanta, nau'ikan ONU daban-daban suna zaɓar tsayin raƙuman ruwa da ake buƙata don karɓar sigina ta masu tacewa na ciki.
Tun da XGS-PON a zahiri yana goyan bayan zaman tare tare da XG-PON, Maganin Combo na XGS-PON yana goyan bayan gauraye damar GPON, XG-PON da XGS-PON nau'ikan ONU uku.Combo Optical module na XGS-PON kuma ana kiransa Mode Combo Optical Module (XG-PON's Combo Optical module ana kiransa nau'in Haɗaɗɗiyar Haɗaɗɗen yanayi biyu saboda yana goyan bayan haɗaɗɗen damar GPON da XG-PON nau'ikan ONU guda biyu).
3. Matsayin Kasuwa
Sakamakon farashin kayan aiki da balaga na kayan aiki, farashin kayan aiki na yanzu na XGS-PON ya fi na XG-PON.Daga cikinsu, farashin naúrar OLT (ciki har da kwamitin mai amfani da Combo) ya kai kusan kashi 20% sama da haka, kuma farashin naúrar ONU ya fi 50% girma.
Kodayake layukan da aka keɓe masu shigowa suna buƙatar samar da da'irori na asymmetrical na sama / ƙasa, ainihin zirga-zirgar mafi yawan layukan sadaukarwa har yanzu suna mamaye da halaye masu zuwa.Ko da yake akwai ƙarin yanayi inda masu amfani ke ba da hankali sosai ga haɓaka bandwidth, kusan babu yanayin sabis ɗin da ba za a iya isa ga ta hanyar XG-PON ba amma dole ne a samu ta hanyar XGS-PON.
