Ngokuvamile, i-transceiver iyidivayisi engathumela futhi yamukele amasignali, kuyilapho i-transponder iyisakhi esinomshini wokucubungula ohlelwe ukuqapha amasignali angenayo futhi sibe nezimpendulo ezihlelwe kusengaphambili kumanethiwekhi okuxhumana e-fiber-optic. Eqinisweni, ama-transponder ngokuvamile abonakala ngesilinganiso sawo sedatha kanye nebanga eliphezulu isignali engahamba ngalo. Ama-Transceiver nama-transponder ahlukile futhi awakwazi ukushintshaniswa. Lesi sihloko sichaza umehluko phakathi kwama-transceiver nama-repeater.
Ama-Transceiver vs. Ama-Transponder: Izincazelo
Ekuxhumaneni kwe-fiber optic, ama-transceiver e-optical aklanyelwe ukudlulisa nokwamukela izimpawu ze-optical. Amamojula e-transceiver asetshenziswa kakhulu ngamadivayisi e-I/O (okufaka/okukhiphayo) ashintshwayo ashisayo, axhunywe kumadivayisi enethiwekhi, njengezishintshi zenethiwekhi, amaseva, nokunye okunjalo. Ama-transceiver e-optical avame ukusetshenziswa ezikhungweni zedatha, amanethiwekhi ebhizinisi, i-cloud computing, izinhlelo zenethiwekhi ze-FTTX. Kunezinhlobo eziningi zama-transceiver, okuhlanganisa ama-transceiver e-1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G ngisho nama-transceiver e-400G. Angasetshenziswa nezintambo noma izintambo zethusi ezahlukahlukene zokudlulisa ibanga elide kumanethiwekhi amafushane noma amade. Ngaphezu kwalokho, kune-transceiver ye-fiber optic ye-BiDi evumela amamojula ukudlulisa nokwamukela idatha nge-fiber eyodwa ukuze kube lula izinhlelo zekhebula, ukwandisa umthamo wenethiwekhi, nokunciphisa izindleko. Ngaphezu kwalokho, amamojula e-CWDM kanye ne-DWDM ahlanganisa ubude obuhlukahlukene be-wavelength ku-fiber eyodwa afanele ukudlulisa ibanga elide kumanethiwekhi e-WDM/OTN.
Umehluko Phakathi Kwe-Transceiver Ne-Transponder
Zombili iziphindaphindi kanye nama-transceiver zingamadivayisi afanayo ngokusebenza aguqula izimpawu zikagesi ezi-duplex ezigcwele zibe izimpawu ezibonakalayo ezi-duplex ezigcwele. Umehluko phakathi kwazo ukuthi i-transceiver ye-optical fiber isebenzisa isikhombikubona esi-serial, esingathumela futhi samukele izimpawu kumojuli efanayo, kuyilapho i-repeater isebenzisa isikhombikubona esihambisanayo, esidinga amamojuli amabili e-optical fiber ukuze kufezwe konke ukudluliselwa. Okusho ukuthi, i-repeater idinga ukuthumela isignali ngemojuli ohlangothini olulodwa, kanti imojuli kolunye uhlangothi isabela kulowo mqondiso.
Nakuba i-transponder ingaphatha kalula amasignali ahambisanayo anezinga eliphansi, inobukhulu obukhulu kanye nokusetshenziswa kwamandla okuphezulu kune-transceiver. Ngaphezu kwalokho, amamojula e-optical angahlinzeka kuphela ngokuguqulwa kukagesi kuya kokukhanya, kuyilapho ama-transponder engafinyelela ukuguqulwa kukagesi kuya kokukhanya kusuka kobude obuthile kuya kobunye. Ngakho-ke, ama-transponder angacatshangwa njengama-transceiver amabili abekwe emuva emuva, okungenzeka kakhulu ukuthi asetshenziswe ekudluliseni ibanga elide ezinhlelweni ze-WDM ezingafinyelelwa ngama-transceiver avamile e-optical.
Ekuphetheni, ama-transceiver nama-transponder ahlukile ngokwemvelo ngomsebenzi kanye nokusetshenziswa. Ama-fibre repeater angasetshenziswa ukuguqula izinhlobo ezahlukene zezimpawu, kufaka phakathi i-multimode ibe yimodi eyodwa, i-dual fiber ibe yi-single fiber, kanye ne-wavelength eyodwa ibe yi-wavelength eyodwa. Ama-Transceiver, angaguqula kuphela izimpawu zikagesi zibe izimpawu ezibonakalayo, asetshenziswe isikhathi eside kumaseva, ukushintsha kwenethiwekhi yebhizinisi, kanye namanethiwekhi esikhungo sedatha.
