Ngokuvamile, i-transceiver iyidivayisi ekwazi ukuthumela nokwamukela amasignali kokubili, kuyilapho i-transponder iyingxenye ephrosesa yayo ehlelelwe ukuqapha amasignali angenayo futhi ibe nezimpendulo ezihlelwe kusengaphambili kumanethiwekhi okuxhumana e-fiber-optic.Eqinisweni, ama-transponder ngokuvamile abonakala ngezinga lawo ledatha kanye nebanga eliphakeme isignali elingahamba ngayo.Ama-transceivers nama-transponder ahlukene futhi awashintsheki.Lesi sihloko sichaza umehluko phakathi kwama-transceivers nama-repeaters.
Ama-Transceivers vs. Transponders: Izincazelo
Ekuxhumaneni kwe-fiber optic, ama-transceivers optical aklanyelwe ukudlulisa nokwamukela amasignali optical.Amamojula e-transceiver asetshenziswa kakhulu angamadivayisi e-I/O (okufakwayo/okuphumayo) ashintshwayo, axhunywe kumadivayisi enethiwekhi, njengamaswishi enethiwekhi, amaseva, nokunye okunjalo.Ama-transceivers optical avame ukusetshenziswa ezikhungweni zedatha, amanethiwekhi ebhizinisi, i-cloud computing, izinhlelo zenethiwekhi ze-FTTX.Kunezinhlobo eziningi zama-transceiver, okuhlanganisa i-1G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G kanye nama-transceivers angu-400G.Zingasetshenziswa ngezinhlobonhlobo zezintambo noma izintambo zethusi zokudlulisa ibanga elide kumanethiwekhi amafushane noma amade.Ngaphezu kwalokho, kunama-transceivers e-BiDi fibre optic avumela amamojula ukuthi adlulise futhi amukele idatha ngefayibha eyodwa ukuze kube lula izinhlelo zekhebula, ukwandisa umthamo wenethiwekhi, nokunciphisa izindleko.Ukwengeza, amamojula e-CWDM kanye ne-DWDM aphindaphinda ubude begagasi obuhlukene ku-fiber eyodwa afaneleka ukudluliswa kwebanga elide kumanethiwekhi e-WDM/OTN.
Umehluko Phakathi Kwe-Transceiver ne-Transponder
Kokubili okuphindaphindayo kanye nama-transceivers kungamadivayisi asebenzayo afanayo aguqula amasiginali kagesi ayiduplex egcwele abe amasiginali we-pull-duplex optical.Umehluko phakathi kwabo ukuthi i-transceiver ye-fiber optical isebenzisa isikhombimsebenzisi se-serial, esingathumela futhi samukele amasignali kumojula efanayo, kuyilapho umphindaphindi esebenzisa isikhombimsebenzisi esihambisanayo, esidinga amamojula amabili e-fiber optical ukufeza konke ukudluliswa.Okusho ukuthi, ophindayo udinga ukuthumela isignali ngemojula ngakolunye uhlangothi, futhi imojula ngakolunye uhlangothi iphendula kuleyo siginali.
Nakuba i-transponder ingakwazi ukuphatha kalula amasiginali ahambisanayo wesilinganiso esiphansi, inosayizi omkhulu kanye nokusetshenziswa kwamandla okuphezulu kune-transceiver.Ukwengeza, amamojula we-optical anganikeza kuphela ukuguqulwa kukagesi kuya ku-optical, kuyilapho ama-transponders angakwazi ukufeza ukuguqulwa kukagesi kuya ku-optical kusuka ku-wavelength eyodwa kuya kwenye.Ngakho-ke, ama-transponders angacatshangwa njengama-transceivers amabili abekwe emuva-kuya-back, okungenzeka ukuthi asetshenziselwe ukudluliswa kwebanga elide ezinhlelweni ze-WDM ezingenakufinyelelwa ngama-transceivers optical ajwayelekile.
Sengiphetha, ama-transceivers nama-transponder ahlukile ngokwemvelo ekusebenzeni nasekusetshenzisweni.Iziphindaphinda ze-Fiber zingasetshenziswa ukuguqula izinhlobo ezahlukene zamasiginali, okuhlanganisa i-multimode iye kwimodi eyodwa, ifayibha ekabili ibe ifayibha eyodwa, kanye nobude begagasi obunye buyise kobunye ubude begagasi.Ama-Transceivers, angaguqula amasignali kagesi kuphela abe amasignali optical, sekuyisikhathi eside esetshenziswa kumaseva, amaswishi enethiwekhi yebhizinisi, namanethiwekhi esikhungo sedatha.
