Ngokukhuphuka kwezidingo kunethiwekhi, amadivaysi enethiwekhi ahlukahlukene akhiqizwa ukuhlangabezana nalezi zidingo.I-Fiber media converter ingenye yezingxenye ezibalulekile kulawo madivayisi.Ifaka umthamo omkhulu womkhawulokudonsa, ukusebenza kwebanga elide nokuthembeka, okwenza idume ezinhlelweni zesimanje zokuxhumana.Lokhu okuthunyelwe kuzohlola isisekelo esithile futhi kukhombisa izibonelo ezimbalwa zohlelo lokusebenza lwe-fiber media converter.

Izisekelo ze-Fiber Media Converter

I-Fiber Media Converter iyithuluzi elingaguqula isignali kagesi ibe amaza okukhanya phakathi kwamanethiwekhi e-UTP yethusi (amapheya asontekile angavikelekile) namanethiwekhi e-fiber optic.Njengoba sonke sazi, uma kuqhathaniswa nekhebula le-Ethernet, izintambo ze-fiber optic zinebanga elide lokudlulisela, ikakhulukazi izintambo ze-fiber mode eyodwa.Ngakho-ke, iziguquli zemidiya ye-fiber zisiza opharetha ukuxazulula inkinga yokudlulisela kahle.
Iziguquli zemidiya ye-Fiber ngokuvamile ziqondene nephrothokholi futhi ziyatholakala ukuze zisekele izinhlobo eziningi zenethiwekhi namazinga edatha.Futhi zihlinzeka ngokuguqulwa kwe-fiber-to-fiber phakathi kwemodi eyodwa ne-multimode fiber.Ngaphandle kwalokho, ezinye iziguquli zemidiya ye-fiber ezifana neziguquli zemidiya ze-copper-to-fiber kanye ne-fiber-to-fiber zinamandla okuguqulwa kwe-wavelength ngokusebenzisa ama-transceivers e-SFP.

Ngokwamazinga ahlukene, iziguquli zemidiya yefiber zingahlukaniswa ngezinhlobo ezahlukene.Kukhona isiguquli semidiya esiphethwe kanye nesiguquli semidiya esingaphethwe.Umehluko phakathi kwabo ukuthi lena yokugcina inganikeza ukuqapha kwenethiwekhi okwengeziwe, ukutholwa kwamaphutha kanye nokusebenza kokucushwa okukude.Kukhona futhi i-copper-to-fiber media converter, i-serial to fibre media converter kanye ne-fiber-to-fiber media converter.

Izicelo Zezinhlobo Ezivamile Zeziguquli Zemidiya Ye-Fiber
Ngezinzuzo ezimbalwa ezishiwo ngenhla, iziguquli zemidiya ye-fiber zisetshenziswa kakhulu ukuvala amanethiwekhi ethusi nezinhlelo zokubona.Le ngxenye ingeyokwethula izinhlobo ezimbili zezinhlelo zokusebenza ze-fiber media converter.

I-Fiber-to-Fiber Media Converter
Lolu hlobo lwe-fiber media converter luvumela ukuxhumana phakathi kwe-fiber mode eyodwa (SMF) kanye ne-multimode fiber (MMF), okuhlanganisa phakathi kwemithombo yefayibha “yamandla” ehlukene naphakathi kwe-fiber eyodwa kanye ne-dual fiber.Okulandelayo ezinye izibonelo zohlelo lokusebenza lwe-fiber-to-fiber media converter.

I-Multimode kuya ku-Single Mode Fiber Application
Njengoba i-SMF isekela amabanga amade kune-MMF, kuvamile ukubona ukuthi ukuguqulwa kusuka ku-MMF kuya ku-SMF kumanethiwekhi ebhizinisi.Futhi i-fiber-to-fiber media converter inganweba inethiwekhi ye-MM yonkana i-SM fiber ngamabanga afika ku-140km.Ngalo mthamo, ukuxhumana kwebanga elide phakathi kwamaswishi amabili e-Gigabit Ethernet kungenziwa kusetshenziswa iziguquli ze-Gigabit fiber-to-fiber (njengoba kukhonjisiwe esithombeni esilandelayo).

Isicelo Sokuguqula I-Dual Fiber ukuya kwe-Single-Fiber
I-Single-fiber ivamise ukusebenza ngamaza angama-bi-directional, avame ukubizwa ngokuthi yi-BIDI.Futhi amaza amaza asetshenziswayo e-BIDI single-fiber angu-1310nm no-1550nm.Kuhlelo lokusebenza olulandelayo, iziguquli ezimbili zemidiya yefayibha ezimbili zixhunywe ngentambo yefayibha yemodi eyodwa.Njengoba kunamaza amaza amabili ahlukene efayibha, isidlulisi nomamukeli emikhawulweni yomibili idinga ukufaniswa.

I-Serial kuya ku-Fiber Media Converter
Lolu hlobo lwesiguquli semidiya luhlinzeka ngesandiso sefayibha ekuxhumekeni kwe-serial yephrothokholi yethusi.Ingaxhunywa ne-RS232, RS422 noma RS485 port yekhompyutha noma ezinye izisetshenziswa, ixazulula izinkinga zokungqubuzana kokuxhumana okungokwesiko kwe-RS232, RS422 noma RS485 phakathi kwebanga nesilinganiso.Futhi futhi isekela iphoyinti-kuya-iphuzu nokucushwa kwamaphuzu amaningi.

RS-232 Isicelo
Iziguquli ze-fiber ze-RS-232 zingasebenza njengamadivayisi asynchronous, ukwesekwa kusheshise kufika ku-921,600 baud, futhi kusekele amasiginali okulawula ukugeleza kwehadiwe okuhlukahlukene ukuze kunikwe amandla ukuxhumeka okungenamthungo namadivayisi amaningi we-serial.Kulesi sibonelo, ipheya yeziguquli ze-RS-232 ihlinzeka ngoxhumano lwe-serial phakathi kwe-PC neseva yetheminali evumela ukufinyelela kumadivayisi edatha amaningi nge-fiber.

RS-485 Isicelo
Iziguquli zefayibha ze-RS-485 zisetshenziswa ezinhlelweni eziningi ezinamaphoyinti amaningi lapho ikhompuyutha eyodwa ilawula amadivaysi amaningi ahlukene.Njengoba kuboniswe esithombeni esingezansi, ipheya yeziguquli ze-RS-485 ihlinzeka ngoxhumano lwamaconsi amaningi phakathi kwezinto zokusingatha kanye namadivayisi axhunywe amaconsi amaningi ngekhebula le-fiber.

Isifinyezo
Ethintwa ukukhawulelwa kwezintambo ze-Ethernet kanye nesivinini esikhulayo senethiwekhi, amanethiwekhi aba nzima nakakhulu.Ukusetshenziswa kweziguquli zemidiya ye-fiber akunqobi kuphela imikhawulo yebanga yezintambo zenethiwekhi evamile, kodwa kunika amandla amanethiwekhi akho ukuthi axhumane nezinhlobo ezahlukene zemidiya njengepheya esontekile, i-fiber ne-coax.

Uma udinga noma yisiphi isiguquli semidiya samaphrojekthi akho e-FTTx & Optical Access kulesi sigaba, sicela usithinte ngokusebenzisainfo@jha-tech.comukuze uthole ulwazi olwengeziwe.
