1.1 module function aasaasiga ah
Thefiber indhahatransceiver ka kooban yahay saddex modules functional aasaasiga ah: photoelectric media chip beddelka, isha signal interface (transceiver isku dhafan module) iyo interface signal koronto (RJ45).Haddii lagu qalabeeyo hawlaha maaraynta shabakada, waxa kale oo ku jira qaybta habaynta macluumaadka maamulka shabakada.
Fiber optic transceiver waa unugga beddelka warbaahinta gudbinta Ethernet kaas oo isweydaarsada calaamadaha korantada ee fogaanta-gaaban ee qalloocan iyo calaamadaha indhaha ee fog-fog.Waxa kale oo meelo badan loogu yeedhaa beddelaha korantada (Fiber Converter).Badeecada waxaa guud ahaan loo isticmaalaa jawiga shabakada dhabta ah halkaas oo fiilada Ethernet aysan dabooli karin iyofiber indhahawaa in loo istcimaalaa in la dheereeyo masaafada gudbinta, waxaana badanaa lagu meeleeyaa codsiga lakabka gelitaanka ee shabakada aagga weyn ee ballaaran;isla mar ahaantaana, waxay kaa caawinaysaa in la isku xidho maylka u dambeeya ee ahfiber indhahaKhadka ilaa magaalo-madaxda Internetka iyo shabakadaha dibadda ayaa iyaguna door wayn ka qaatay.
Qaar ka mid ah ganacsiyada waaweyn, fiber indhaha ayaa loo isticmaalaa sidii dhexdhexaadiyaha gudbinta si loo dhiso shabakad laf dhabarta inta lagu jiro dhismaha shabakada, halka dhexdhexaadinta gudbinta LAN gudaha guud ahaan tahay silig naxaas ah.Sida loo ogaado xidhiidhka ka dhexeeya LAN iyofiber indhahashabakada laf dhabarta?Tani waxay u baahan tahay beddelka u dhexeeya dekedo kala duwan, khadadka kala duwan, iyo fiilooyinka indhaha ee kala duwan waxayna dammaanad qaadaysaa tayada isku xirka.Soo ifbaxa transceivers fiber optical waxay u beddeleysaa calaamadaha korantada iyo indhaha ee lammaanaha qalloocan midba midka kale, hubinta gudbinta fudud ee xirmooyinka xogta ee labada shabakadood, isla markaana, waxay kordhisaa xadka fogaanta gudbinta ee shabakadda 100 mitir. ee fiilooyinka naxaasta ilaa in ka badan 100 kiiloomitir (Silig-mode fiber).
1.2 Astaamaha aasaasiga ah ee transceivers fiber optic

Isticmaal chip ASIC go'an si aad u xaqiijiso gudbinta xawliga xogta.Barnaamijka ASIC waxay xooga saartaa hawlo badan oo hal jajab ah, waxayna leedahay faa'iidooyinka naqshadda fudud, kalsoonida sare, iyo isticmaalka tamarta hooseeya, taas oo awood u siin karta qalabka si ay u helaan waxqabad sare iyo qiimo hoose.
5. Qalabka maamulka shabakadu wuxuu bixin karaa ogaanshaha shabakada, cusboonaysiinta, warbixinta heerka, warbixinta xaalada aan caadiga ahayn iyo hawlaha xakamaynta, wuxuuna bixin karaa diiwaanka hawlgalka oo dhamaystiran iyo diiwaanka digniinta.
6. Qalabka nooca rack-ka ah wuxuu ku siin karaa shaqo kuleyl ah oo la isku bedeli karo si loo dayactiro fudud iyo hagaajin aan kala go 'lahayn.
7. Taageer masaafada gudbinta dhamaystiran (0～120km).
8. Qalab badankoodu waxa ay qaataan nashqad koronto oo ah 1+1, waxa ay taageeraan danab koronto oo aad u ballaaran, waxa ayna garwaaqsadaan ilaalinta sahayda korontada iyo beddelka tooska ah.
1.3Kala soocida transceivers fiber optic
Waxaa jira noocyo badan oo fiber optic transceivers ah, iyo noocyadooda isbeddelka si waafaqsan hababka kala soocida.
Sida laga soo xigtay dabeecadda fiber-ka, waxa loo qaybin karaa transceiver fiber-mode-ka badan iyo transceiver fiber-ka hal-mode ah.Sababtoo ah fiilooyinka indhaha ee kala duwan ee la isticmaalo, fogaanta gudbinta ee transceiver waa ka duwan yahay.Masaafada guud ee gudbinta transceivers-yada kala duwan waa inta u dhaxaysa 2 kiiloomitir iyo 5 kiiloomitir, halka daboolida transceivers-ka-hal-halku u dhaxayn karo 20 kiiloomitir ilaa 120 kiiloomitir;
Sida laga soo xigtay fiber optic-ga loo baahan yahay, waxaa loo qaybin karaa hal-fiber optic fiber transceiver: xogta la diro oo la helo waxaa lagu kala qaadaa hal fiber indhaha;transceiver-ka laba-fiber optical fiber transceiver: xogta la helo oo la soo diro waxaa lagu kala qaadaa labo ka mid ah fiilooyinka indhaha.
Marka loo eego heerka shaqada, waxaa loo qaybin karaa hal 10M, 100M fiber optic transceivers, 10/100M transceivers fiber optic adaptive iyo 1000M fiber optic transceivers.Marka loo eego qaab-dhismeedka, waxa loo qaybin karaa desktop-ka (kaligii-taag) transceivers fiber optic iyo rack-ku rakiban fiber optic transceivers.Transceiver fiber optical desktop-ka ayaa ku habboon hal isticmaale, sida la kulanka kor u qaadista hal beddelka ee marinka.Rack-ku rakiban (modular) transceivers fiber optic waxay ku habboon yihiin isu geynta isticmaalayaasha badan.Tusaale ahaan, qolka kombayuutarka dhexe ee beesha waa inuu buuxiyaa isku xidhka dhammaan furayaasha bulshada.
zccording in maamulka shabakada, waxa loo qaybin karaa nooca maamulka network transceiver fiber indhaha iyo non-network maareyn transceiver fiber indhaha.
Marka loo eego nooca maamulka, waxaa loo qaybin karaa maamul aan shabakad ahayn Ethernet fiber optic transceivers: fur oo ciyaar, deji habka shaqada ee dekedda korantada iyada oo loo marayo furaha garaaca qalabka.Nooca maamulka shabakada Ethernet fiber optic transceiver: taageer maaraynta shabakada heerka side
Marka loo eego nooca sahayda korantada, waxa loo qaybin karaa ku-dhex-dhismay koronto fibre optic transceivers:-ku-xidhan sahayda korantada waa sahay koronto-qaade;transceivers fiber optic koronto dibadda: sahay koronto koronto dibadda ah waxaa inta badan loo isticmaalaa qalabka rayidka ah.Faa'iidada tan hore waa in ay taageerto koronto koronto oo aad u ballaaran, si fiican u xaqiijinta xasilinta korantada, shaandhaynta iyo ilaalinta awoodda qalabka, iyo in la yareeyo dhibcooyinka fashilka dibadda ee ay keento xiriirka farsamada;Faa'iidada tan dambe waa in qalabku uu yar yahay cabbirkiisuna jaban yahay.
Waxaa loo qaybiyaa habka shaqada, qaabka buuxa ee duplex (duplex buuxa) waxay ka dhigan tahay marka diritaanka iyo helitaanka xogta loo kala qaybiyo laba xariiq oo kala duwan, labada dhinac ee isgaarsiintu waxay diri karaan oo heli karaan isku mar.Gudbinta noocan oo kale ah Habkani waa laba-duplex, iyo qaabka-duplex-ka buuxa uma baahna inuu beddelo jihada, sidaas darteed ma jiro dib-u-dhac waqti ah oo uu keeno hawlgalka beddelka;
Duplex-ka badhku waxa loola jeedaa isticmaalka isla xariiqda gudbinta ee soo dhawaynta iyo diridaba.Inkasta oo xogta loo kala gudbin karo laba jiho, labada dhinac ee isgaadhsiintu isku mar ma diri karaan oo ma heli karaan xogta.Habkan gudbinta waa nus-duplex.
Marka habka nus-duplex-ka la qaato, gudbiyaha iyo qaataha dhammaadka kasta ee nidaamka isgaarsiinta ayaa loo wareejiyaa khadka isgaarsiinta iyada oo loo marayo furaha aqbalka/diridda si loogu beddelo jihada.Sidaa darteed, dib u dhac waqti ayaa dhici doona.
