I-Optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ihlukaniswe ikakhulukazi ngama-transceiver optical optical-fiber eyodwa kanye nama-transceiver optical amabili-fiber ngokwezidingo zawo Okulandelayo, sizokwethula ngokuningiliziwe ukuthi iyini i-single-fiber / dual-fiber optical transceiver? Yimuphi umehluko phakathi kwama-transceivers e-single-fiber ye-single-fiber kanye ne-dual-fiber transceivers yemodi eyodwa? Bangane abanentshisekelo, ake sibheke!
Iyini i-single-fiber optical transceiver yemodi eyodwa?
I-single-fiber optical fiber transceiver yemodi eyodwa, imishini ye-fiber eyodwa ingagcina ingxenye ye-fiber optical, okungukuthi, ukwamukela idatha nokudluliswa kwe-fiber eyodwa.
I-single-fiber optical fibre transceiver: Idatha etholiwe futhi yadluliselwa idluliselwa ngefayibha eyodwa yokubona. Njengoba igama lisho, imishini ye-fiber eyodwa ingagcina ingxenye ye-fiber optical, okungukuthi, ukwamukela nokuthumela idatha ku-fiber eyodwa, efaneleka kakhulu ezindaweni lapho izinsiza ze-fiber ziqinile. Lolu hlobo lomkhiqizo lusebenzisa ubuchwepheshe be-wavelength division multiplexing, kanti ubude begagasi obusetshenzisiwe ngokuvamile bungu-1310nm no-1550nm. Kodwa-ke, ngenxa yokuthi alikho izinga elihlanganisiwe lamazwe ngamazwe lemikhiqizo ye-transceiver ye-fiber eyodwa, imikhiqizo yabakhiqizi abahlukene ingase ingahambisani lapho ixhumeke. Ngaphezu kwalokho, ngenxa yokusetshenziswa kwe-wavelength division multiplexing, imikhiqizo ye-transceiver ye-single-fiber ngokuvamile inezici zokunciphisa isignali enkulu. Njengamanje, ama-transceiver amaningi e-fiber optical emakethe ayimikhiqizo ye-dual-fiber. Imikhiqizo enjalo ivuthiwe futhi izinzile, kodwa idinga imicu ye-optical eyengeziwe.
Iyini i-transceiver ebonakalayo yemodi eyodwa ye-dual-fiber?
I-transceiver optical yemodi eyodwa ye-fiber-fiber eyodwa-fiber bidirectional iyimishini yokuguqula i-photoelectric, inzuzo iwukugcina isigamu se-fiber optical.
I-Single-fiber bidirectional optical fiber transceiver iyithuluzi lokuguqula i-photoelectric esebenzisa ubuchwepheshe be-wavelength division multiplexing ukuze idlulise futhi yamukele idatha ku-fiber optical eyodwa futhi iguqule amasignali kagesi wenethiwekhi namasignali optical. I-single-fiber bidirectional fibre optic transceivers isidumile eminyakeni yamuva nje. Inzuzo yukuthi ingasindisa ingxenye yefiber optical, kanti ukuntuleka kwengxenye yefiber optical ukuthi okwamanje ayikho indinganiso yamazwe ngamazwe ehlangene. Imikhiqizo ekhiqizwa abakhiqizi abahlukahlukene ivamise ukuhambisana futhi izinzile kancane kunemikhiqizo ye-dual-fiber. Njengamanje, ama-transceiver e-fiber optic emakethe asabuswa yimikhiqizo ye-dual-fiber.
Uyini umehluko phakathi kwama-transceivers e-single-fiber yemodi eyodwa kanye nama-transceivers e-dual-fiber yemodi eyodwa?
I-multimode yemodi eyodwa incike kukhebuli yokubona. I-Single-fiber dual-fiber ibhekisela ekudluliselweni kwe-fiber optical ene-core eyodwa noma ukudluliswa kwe-fiber optical ene-core core; imodi eyodwa ibhekisela ekusebenziseni intambo yefibre yemodi eyodwa. Zombili zixhunywe kulo mgogodla, futhi ama-transceivers emikhawulweni yomibili asebenzisa ama-wavevel optical ahlukene, ukuze akwazi ukudlulisa amasignali optical kumongo owodwa. I-transceiver ene-dual-fiber isebenzisa ama-cores amabili, eyodwa ukuthumela futhi enye ukwamukela, futhi enye ukuphela ukuphela kokuthumela futhi enye ekugcineni kufanele ifakwe embotsheni eyamukelayo, okungukuthi, iziphetho ezimbili kufanele ziwele.
Ezinhlelweni ezithile, imodi ekabili yemodi eyodwa, inani lemodi eningi liphezulu kunemodi eyodwa, ikakhulukazi ebangeni lezintambo elingaphansi kuka-500m, imodi eminingi ingavele ihlangane, nakuba ukusebenza kungekuhle njengokukodwa. -imodi. Imodi eyodwa isetshenziswa endaweni enezidingo ezingaphezu kwama-500m noma zomkhawulokudonsa ophezulu, ikakhulukazi ezindaweni ezinkulu ezifana nezinhlelo zokusebenza ezisezingeni lebhizinisi. Ngenxa yokuthi ukuzinza nokusebenza kwamamojula we-fiber optical kungcono kakhulu kunama-transceivers, ezindaweni zesicelo semodi eyodwa enezidingo eziphezulu zokusebenza, izinkampani ezimbalwa zizosebenzisa ama-transceivers, kodwa zisebenzisa ngokuqondile amamojula esikhundleni. Bambalwa abakhiqizi bama-analogue transceiver namanani aphezulu.
Ifayibha eyodwa kanye nefayibha ekabili ngokuvamile inamachweba amabili, futhi izimbobo ezimbili zefayibha ekabili zisondelene. Amakwe TX, RX, transmit eyodwa futhi eyodwa wamukela, ngokulandelana. Izimbobo ezimbili zefayibha eyodwa ngokuvamile ziyi-P1. I-P2 ikhombisa ukuthi zombili izimbobo zingathunyelwa futhi zamukelwe ngokwehlukana, okungukuthi, imbobo eyodwa isetshenziselwa ukuthumela nokwamukela, ngakho ibizwa ngokuthi i-fiber eyodwa. Ama-transceiver optical TX kanye ne-RX amele ukwamukela nokuthumela. Kunezinhlobo ezimbili zama-transceiver optical: eyodwa iyimodi eyodwa futhi enye ine-dual-mode, njengemigwaqo emikhulu ingase iminyaniswe kuphela uma kunomugqa owodwa kuphela, kodwa ishelela kakhulu uma imigqa emibili, ngakho-ke. kusobala ukuthi ukuzinza kwesamukeli semodi ekabili Iphuzu elihle.
I-fiber eyodwa iwukuxhumana kwefayibha eyodwa phakathi kwama-transceiver amabili, i-dual fiber ivame kakhulu, udinga ukusebenzisa imicu emibili, intengo ye-fiber eyodwa iphakeme kancane. I-transceiver yemodi eminingi ithola izindlela zokudlulisa eziningi, ibanga lokudlulisela lifushane, futhi i-transceiver yemodi eyodwa ithola imodi eyodwa kuphela; ibanga lokudlulisela lide uma kuqhathaniswa. Nakuba i-multi-mode iqedwa, kodwa ngenxa yentengo ephansi, zisekhona eziningi ezisetshenziselwa ukuqapha kanye nokudluliswa kwebanga elifushane. Ama-transceivers emodi eningi ahambisana namafiber optical enemodi eminingi, imodi eyodwa kanye nemodi eyodwa ahambisana, futhi awakwazi ukuxutshwa.
