Ngokunyuka kweemfuno kuthungelwano, izixhobo ezahlukeneyo zothungelwano ziyenziwa ukuhlangabezana nezi mfuno.I-Fiber media converter yenye yezinto eziphambili kwezo zixhobo.Ineempawu zomthamo we-bandwidth ephezulu, ukusebenza komgama omde kunye nokuthembeka, okwenza ukuba idume kwiinkqubo zenethiwekhi zanamhlanje.Esi sithuba siza kuphonononga isiseko esithile kwaye sibonisa imizekelo emininzi yesicelo soguqulelo lwefiber media.

Iziseko zeFiber Media Converter

I-Fiber Media Converter sisixhobo esinokuguqula umqondiso wombane ube ngamaza okukhanya phakathi kobhedu lwe-UTP (isibini esijijekileyo esingakhuselekanga) uthungelwano kunye nothungelwano lwefiber optic.Njengoko sonke sisazi, xa kuthelekiswa nentambo ye-Ethernet, iintambo zefiber optic zinomgama omde wothumelo, ngakumbi iintambo zefayibha zemowudi enye.Ke ngoko, abaguquli bemidiya yefiber banceda abaqhubi ukuba basombulule ingxaki yothumelo ngokugqibeleleyo.
Iziguquli zemidiya yeFayibha ziqhelekile kwiprothokholi ethile kwaye ziyafumaneka ukuxhasa iintlobo ngeentlobo zenethiwekhi kunye namazinga edatha.Kwaye babonelela ngoguqulo lwefayibha ukuya kwifayibha phakathi kwemowudi enye kunye nefayibha ezininzi.Ngaphandle koko, ezinye iziguquli zemidiya yefayibha ezifana ne-copper-to-fiber kunye ne-fiber-to-fiber media converters zinamandla okuguqulwa kwe-wavelength ngokusebenzisa ii-transceivers ze-SFP.

Ngokwemigangatho eyahlukeneyo, abaguquli bemidiya yefayibha banokuhlelwa ngokweendidi ezahlukeneyo.Kukho isiguquli semidiya elawulwayo kunye nesiguquli semidiya esingalawulwayo.Umahluko phakathi kwabo kukuba lo wokugqibela unokubonelela ngokujongwa kwenethiwekhi eyongezelelweyo, ukufumanisa impazamo kunye nokusebenza koqwalaselo olude.Kukwakho necopper-to-fiber media converter, iserial to fiber media converter kunye nefiber-to-fiber media converter.

Ukusetyenziswa kweendidi eziqhelekileyo zeFayibha Media Converters
Ngeengenelo ezininzi ezikhankanywe ngasentla, abaguquli bemidiya yefayibha basetyenziswa ngokubanzi ukubhula uthungelwano lobhedu kunye neenkqubo zokukhanya.Eli candelo lelokuqala ukwazisa iindidi ezimbini zefiber media converter izicelo.

IFayibha ukuya kwiFayibha Media Converter
Olu hlobo lwe-fiber media converter lwenza uxhulumaniso phakathi kwe-fiber mode eyodwa (SMF) kunye ne-multimode fiber (MMF), kubandakanywa phakathi kwemithombo yefiber eyahlukeneyo "yamandla" kunye phakathi kwe-fiber enye kunye ne-fiber ezimbini.Ilandelayo yimizekelo yesicelo ye-fiber-to-fiber media converter.

I-Multimode kwi-Single Mode yeFayibha Isicelo
Kuba i-SMF ixhasa imigama emide kune-MMF, kuqhelekile ukubona ukuba uguqulo ukusuka kwi-MMF ukuya kwi-SMF kuthungelwano lwamashishini.Kwaye i-fiber-to-fiber media converter inokwandisa inethiwekhi ye-MM kwi-fiber ye-SM kunye nomgama ukuya kwi-140km.Ngolu mthamo, unxibelelwano lomgama omde phakathi kweeswitshi ezimbini zeGigabit Ethernet zinokuqondwa kusetyenziswa iperi yeGigabit fiber-to-fiber converters (njengoko kubonisiwe kulo mfanekiso ulandelayo).

IFayibha ezimbini kwiSicelo soGuqulo seFayibha enye
Ifayibha enye idla ngokusebenza ngamaza obude be-bi-directional, edla ngokubizwa ngokuba yi-BIDI.Kwaye amaza aqhele ukusetyenziswa e-BIDI-fiber enye yi-1310nm kunye ne-1550nm.Kwesi sicelo silandelayo, iziguquli ezimbini zefiber media media zidityaniswe yintambo yefiber yemowudi enye.Kuba kukho amaza amabini ahlukeneyo kwifiber, isidluliseli kunye nomamkeli kuzo zombini iziphelo kufuneka zihambelane.

Uthotho ukuya kwiFayibha Media Converter
Olu hlobo lwesiguquli semidiya lubonelela ngefayibha ukwandiswa koqhagamshelo lweprotocol yobhedu.Inokudityaniswa ne-RS232, RS422 okanye i-RS485 port yekhompyutha okanye ezinye izixhobo, ukusombulula iingxaki ze-RS232 yendabuko, i-RS422 okanye i-RS485 ingxabano yonxibelelwano phakathi komgama kunye nomlinganiselo.Kwaye ikwaxhasa i-point-to-point kunye noqwalaselo lwamanqaku amaninzi.

RS-232 Isicelo
I-RS-232 i-fiber converters inokusebenza njengezixhobo ze-asynchronous, isantya senkxaso ukuya kwi-921,600 baud, kunye nokuxhasa uluhlu olubanzi lweempawu zokulawula ukuhamba kwe-hardware ukwenzela ukuba unxibelelwano olungenamthungo kunye nezixhobo ezininzi ze-serial.Kulo mzekelo, ibini labaguquli be-RS-232 banikezela uxhulumaniso lwe-serial phakathi kwePC kunye ne-terminal server evumela ukufikelela kwizixhobo ezininzi zedatha ngefiber.

RS-485 Isicelo
I-RS-485 i-fiber converters isetyenziswa kwizicelo ezininzi ze-multi-point apho ikhompyutha enye ilawula izixhobo ezininzi ezahlukeneyo.Njengoko kuboniswe kumfanekiso ongezantsi, ibini labaguquli be-RS-485 banikezela uxhulumaniso lwe-multi-drop phakathi kwezixhobo zokusingatha kunye nezixhobo ezidibeneyo zokulahla ezininzi nge-fiber cable.

Isishwankathelo
Ukuchatshazelwa kukuncitshiswa kweentambo ze-Ethernet kunye nokunyuka kwezantya zenethiwekhi, uthungelwano luba nzima ngakumbi.Ukusetyenziswa kweziguquli zemidiya yefayibha akupheleli nje koyisa imida yomgama weentambo zenethiwekhi zesiqhelo, kodwa zenza uthungelwano lwakho lunxibelelane neentlobo ezahlukeneyo zemidiya ezinje ngeperi ejijekileyo, ifayibha kunye ne-coax.
