Ingabe ama-transceiver e-fiber optic kufanele asetshenziswe ngababili?Ingabe kukhona ukuhlukana kwe-fiber transceiver?Noma ipheya nje yama-transceiver e-fiber optic angasetshenziswa ukwakha ipheya? Uma ama-fibre transceivers kumele asetshenziswe ngababili, ingabe iwuphawu olufanayo nemodeli? Noma ungasebenzisa noma iyiphi inhlanganisela yemikhiqizo?
Impendulo: Ama-transceivers okubona ngokuvamile asetshenziswa ngababili njengamadivayisi okuguqula i-photoelectric. Kodwa-ke, kungenzeka futhi ukusebenzisa ama-transceivers optical kanye ne-fiberamaswishi, ama-fiber transceivers kanye nama-transceivers e-SFP. Empeleni, inqobo nje uma ubude begagasi be-optical transmission bufana, ukuxhumana kwe-Fiber-optic kungafinyelelwa ngefomethi efanayo ye-encapsulation yesignali nokusekela iphrothokholi ethile.
Ngokuvamile, ama-dual-fiber (ama-fiber amabili adingekayo ekuxhumaneni okuvamile) ama-transceivers awahlukaniswanga ekugcineni kokudlulisela kanye nesiphetho sokwamukela. I-transceiver ene-fiber eyodwa kuphela (edinga ifayibha eyodwa ekuxhumaneni okuvamile) ezoba nesiphetho sokudlulisa kanye nesiphetho sokwamukela.
Noma ngabe i-dual-fiber transceiver noma i-single-fiber transceiver, iyahambisana ukusebenzisa amabhrendi ahlukene ngamabili. Kodwa-ke, amanani ahlukene (amamegabhithi angu-100 namagigabhayithi) namaza amaza ahlukene (1310 nm no-1300 nm) awahambisani. Ngaphezu kwalokho, ngisho ne-transceiver ye-fiber eyodwa yomkhiqizo ofanayo kanye namapheya e-dual-fiber kanye namapheya e-dual-fiber awakwazi ukusebenzisana.
I-dual-fiber transceiver inembobo ye-TX (imbobo yokudlulisa) kanye nembobo ye-RX (imbobo eyamukelayo). Zombili izimbobo zikhipha ubude begagasi obufanayo buka-1310 nm, nokwamukelayo nakho kungu-1310 nm, ngakho imicu emibili ehambisanayo ixhunywe ekuxhumekeni okunqamulayo. . Isebenzisa ubuchwepheshe be-wavelength division multiplexing ukuze idlulise futhi yamukele amasiginali amabili okubona amaza ahlukene e-wavelengths ku-fiber optical eyodwa. Ngokuvamile basebenzisa amaza wamaza angu-1310 nm no-1550 nm.
Izinhlobo ezahlukene zama-transceiver optical zisekela amaphrothokholi e-Ethernet. Bangakwazi ukuxhumana nama-transceiver anencazelo efanayo, kodwa amanye ama-transceiver engeza imisebenzi ethile (efana nokwenza isibuko) futhi asekele amaphrothokholi athile. Endabeni yecala alisekelwe.
