Fiber to the Home (FTTH) isystem inoisa mafiber optics kubva pakati pezvivakwa zvakanangana nedzimba sedzimba nemafurati. FTTH deployment yasvika kure vashandisi vasati vatora fiber optics pachinzvimbo chemhangura yeBroadband Internet yekuwana.
Pane nzira mbiri dzekutanga dzekuendesa yakakwira-kumhanya FTTH network:anoshanda optical network(AON) uye passiveoptical network(PON).
Saka AON nePON network: chii mutsauko?
Chii chinonzi AON network?
An AON inzvimbo-ku-point network architecture umo munyoreri wega wega ane yake fiber optic mutsara iyo inogumiswa pane optical concentrator. inetiweki yeAON inotenderedza magetsi emagetsi ekuchinjisa zvishandiso semarouter kana kushandura aggregator kubata kugovera kwechiratidzo uye kusaina kwakananga kune chaivo vatengi.
Kushandura kunovhurwa uye kuvharwa nenzira dzakasiyana-siyana dzekutungamira zviratidzo zvinopinda uye zvinobuda kune nzvimbo dzakakodzera.Iyo AON network inotsamira paEthernet teknolojia inoita kuti kudyidzana pakati pevanopa zvive nyore. Vanyoreri vanogona kusarudza Hardware inopa yakakodzera data mazinga uye kukwira kumusoro sezvo zvavanoda zvichiwedzera pasina kugadzirisa zvakare network. Nekudaro, AON network inoda inokwana imwe switch aggregator pamunhu anonyoresa.
Chii chinonzi PON network?
Kusiyana neAON network, PON inzvimbo-kune-multipoint network architecture inoshandisa passive splitters kuparadzanisa uye kuunganidza masaini masaini. Fiber splitters inobvumira network yePON kuti ishumire vanyori vakawanda mufiber imwe chete pasina chikonzero chekuisa mafibhi akaparadzana pakati pehubhu nemushandisi wekupedzisira.
Sezvinoratidzwa nezita racho, maPON network haasanganisire mota yekuchinja midziyo uye kugovera mafibha masumbu ezvikamu zvetiweki. Active midziyo inongodiwa pane kwazvino uye kugamuchira migumo yechiratidzo.
Mune yakajairika PON network, iyo PLC splitter ndiyo yepakati. Fiber optic taps inosanganisa akawanda masaini masaini kuita imwe chete inobuda, kana fiber optic taps inotora imwechete yekuona yekuisa uye kuigovera kune akawanda ega anobuda. Aya matepi ePON ane bidirectional. Kuti zvive pachena, masaini efiber optic anogona kutumirwa pasi kubva kuhofisi yepakati kuti atepfenyure kune vese vanyoreri. Zviratidzo kubva kune vanyoreri zvinogona kutumirwa kumusoro uye kusanganiswa kuita imwe fiber kutaurirana nehofisi yepakati.
AON vs PON Networks: Misiyano uye Sarudzo
Ose maPON neAON network anoumba iyo fiber optic musana weFTTH system, ichibvumira vanhu nemabhizinesi kuwana iyo Internet. Usati wasarudza PON kana AON, zvakakosha kunzwisisa kusiyana pakati pavo.
Signal Distribution
Kana zvasvika kune AON nePON network, musiyano mukuru pakati pavo inzira iyo chiratidzo chemaziso chinogoverwa kune mumwe nemumwe mutengi muFTTH system. Muchirongwa cheAON, vanyoreri vakatsaurira masumbu efiber, izvo zvinovatendera kuti vawane mukana kune imwechete bandwidth, pane yekugovaniswa. Mune network yePON, vanyoreri vanogovana chikamu chetiweki fiber bundle muPON. Nekuda kweizvozvo, vanhu vanoshandisa PON vanogona zvakare kuona kuti system yavo inonoka nekuti vese vashandisi vanogovana bandwidth yakafanana. Kana dambudziko rikaitika mukati mePON system, zvinogona kuve zvakaoma kuwana kwainobva dambudziko.
Mariro
Mutengo mukuru unoenderera mberi munetiweki mutengo wemagetsi ekushandisa uye kugadzirisa. PON inoshandisa zvigadziriso zvinoda kugadziriswa zvishoma uye pasina magetsi kupfuura AON network, inova network inoshanda. Saka PON yakachipa kupfuura AON.
Kuvhara Distance uye Applications
AON inogona kuvhara chinhambwe chinosvika makiromita makumi mapfumbamwe, nepo PON ichiwanzoganhurwa netambo dzefiber optic dzinosvika makiromita makumi maviri kureba. Izvi zvinoreva kuti vashandisi vePON vanofanirwa kunge vari padyo nenzvimbo yechiratidzo.
Uye zvakare, kana yakabatana neimwe application kana sevhisi, akati wandei zvimwe zvinhu zvinoda kutariswa. Semuyenzaniso, kana RF nemavhidhiyo masevhisi achizoiswa, ipapo PON kazhinji ndiyo yega mhinduro inoshanda. Nekudaro, kana masevhisi ese ari Internet Protocol-based, ipapo PON kana AON inogona kunge yakakodzera. Kana madaro marefu achibatanidzwa uye kupa simba uye kutonhora kuzvinhu zvinoshanda mumunda zvinogona kunetsa, saka PON inogona kunge iri sarudzo yakanyanya kunaka. Kana, kana mutengi anotarisirwa ari kutengeserana kana purojekiti inosanganisira nzvimbo dzakawanda dzekugara, saka network yeAON inogona kuve yakakodzera.
AON vs. PON Networks: Ndeipi FTTH yaunoda?
Pakusarudza pakati pePON kana AON, zvakakosha kuti utarise kuti ndeapi masevhisi achaunzwa pamusoro penetiweki, iyo yakazara network topology, uye kuti vatengi vekutanga ndivanaani. Vazhinji vashandisi vakaisa musanganiswa wemaseti ese ari maviri mumamiriro akasiyana. Nekudaro, sezvo kudiwa kwekudyidzana kwetiweki uye scalability kuri kuramba kuchikura, magadzirirwo etiweki ari kuda kubvumira chero faibha kuti ishandiswe zvakasiyana muPON kana AON application kuti isangane nezvinodiwa zvezvido zvemangwana.
