Kuma-transceivers e-fiber optical, umsebenzi oyinhloko we-transceiver ukunweba ibanga lokudluliswa kwenethiwekhi, okunganciphisa iphutha lokuthi ikhebula lenethiwekhi alikwazi ukudlulisa ibanga elide ngokwezinga elithile, futhi ilethe ukunethezeka ekudlulisweni kwekhilomitha lokugcina, kodwa kulabo. abasha ku-transceiver Amanye amaphutha avame kakhulu enziwa abantu, njengokungahlukaniswa kwesiphetho sokudlulisela kanye nokwamukela ukuphela kwe-fiber optic. i-transceiver. Kungani ama-transceiver e-fiber optic ehlukaniswa abe isidlulisi nomamukeli? Ingabe ukuphela kwe-A/B kwe-fiber optic transceiver kungaxhunywa ngokunganaki?

I-ab end ye-fiber optic transceiver kufanele ibe isiphetho sokudlulisa (isiphetho) kanye nesiphetho sokwamukela (b end). Isizathu sokuthi kungani i-transceiver ihlukaniswe ekugcineni kokudlulisela kanye nesiphetho sokwamukela ukuthi i-transceiver idinga ukudlulisa isignali kabili lapho isetshenziswa, ngokuvamile ngamabili. Abantu abaningi basebenzisa ama-transceiver anefayibha eyodwa emakethe; Iziphetho ezimbili ze-transceiver eyodwa-fiber yi-A-end kanye ne-B-end ngokulandelana. Ama-wavelength kulezi ziphetho ezimbili ahlukile. Ubude begagasi bomkhawulo wokudlulisa bufushane kunalelo lokuphela kokwamukela. Eqinisweni, i-dual-fiber transceiver ayinawo u-A no-B, ngoba amaza obude emikhawulweni yomibili ayafana. Kuphela uma uxhuma isiphetho se-TX (esidlulisayo) kanye nesiphetho se-RX (eyamukelayo), i-fiber eyodwa, njengoba negama libonisa, iyi-fiber optical, futhi abanye ochwepheshe bayibiza ngokuthi i-transceiver eyodwa-core, okubhekisela ekuthumeleni nasekutholeni amasignali emikhawulweni yomibili ku-fiber eyodwa optical, ngoba kumodi eyodwa Imojula ye-optical esetshenziswa ngaphakathi kwe-transceiver ye-fiber eyodwa inamaza amabili okukhanya okukhishiwe, kuyilapho i-dual-fiber ixhunywe ngokuphambana ngamafiber optical amabili, futhi ibhulokhi yefilimu ebonakalayo yangaphakathi inobude obubodwa kuphela.

Ama-transceivers e-fiber optical ahlukaniswe abe yi-single-mode dual-fiber optical fibre transceivers kanye ne-single-fiber optical fiber transceivers yemodi eyodwa ngokwenani lama-fiber cores. I-transceiver ye-single-fiber transceiver idluliselwa nge-core optical fiber, ngakho kokubili ukukhanya okudlulisiwe nokwamukelwe kudluliselwa ngomgogodla owodwa we-fiber optical ngesikhathi esifanayo.Kulokhu, ukuze kuzuzwe ukuxhumana okuvamile, amaza okukhanya amabili kufanele abe esetshenziswa ukuhlukanisa. Ngakho-ke, i-module ye-optical ye-transceiver ye-single-fiber ye-fiber ine-wavelengths emibili yokukhanya, ngokuvamile i-1310nm / 1550nm, futhi ibanga elide liyi-1490nm / 1550nm. Ngale ndlela, kuzoba nomehluko phakathi kweziphetho ezimbili zokuxhumanisa kwepheya lama-transceivers, futhi umkhawulo owodwa we-transceiver uzohluka. Dlulisa i-1310nm futhi uthole i-1550nm. Esinye isiphetho ukudlulisa i-1550nm bese uthola i-1310nm. Ngakho-ke kulula kubasebenzisi ukuhlukanisa, futhi izinhlamvu zivame ukusetshenziswa esikhundleni salokho. Bese kuba ne-a-end (1310nm/1550nm) kanye ne-B-end (1550nm/1310nm). Abasebenzisi kufanele basebenzise ukubhanqa kwe-ab. Ukuxhumeka kwe-Aa noma kwe-bb akuvunyelwe.
