I-Optical fibre transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasiginali kagesi asontekile amabanga amafushane kanye namasiginali okubona amabanga amade. Ngokwezidingo zayo, ihlukaniswe ikakhulukazi ngama-fiber optical transceivers kanye nama-transceiver optical amabili-fiber.Okulandelayo, sizokwethula ngokuningiliziwe ukuthi iyini i-single-fiber / dual-fiber optical transceiver? Yimuphi umehluko phakathi kwama-transceivers abonakalayo we-single-fiber kanye nemodi eyodwa ye-dual-fiber optical transceivers? Uma unentshisekelo, ake sibheke!

Yini ai-transceiver ebonakalayo ye-single-fiber?

I-transceiver ye-fiber optical yemodi eyodwa ye-single-fiber, imishini ye-fiber eyodwa ingagcina isigamu se-fiber optical, okungukuthi, ukufeza ukwamukela idatha nokudluliswa kwe-fiber optical eyodwa.

I-single-fiber optical fiber transceiver: Idatha etholiwe futhi yathunyelwa idluliselwa ngefayibha yokubona. Njengoba igama libonisa, imishini ye-fiber eyodwa ingagcina ingxenye ye-fiber optical, okungukuthi, ukwamukela nokuthumela idatha ku-fiber eyodwa optical, efaneleka kakhulu ezindaweni lapho izinsiza ze-fiber optical ziqinile. Lolu hlobo lomkhiqizo lusebenzisa ubuchwepheshe be-wavelength division multiplexing, futhi iningi lamaza asetshenziswayo yi-1310nm kanye ne-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 zokunqanda isignali enkulu. Njengamanje, iningi lama-transceivers e-fiber optic emakethe yimikhiqizo ye-dual-fiber, evuthiwe futhi ezinzile, kodwa edinga imicu eyengeziwe.

Yini ai-transceiver ebonakalayo yemodi eyodwa ye-dual-fiber?

I-transceiver ye-fiber optical yemodi eyodwa yemodi eyodwa, kanye nohlobo lwe-fiber optical optical transceiver ye-single-fiber yimishini yokuguqula i-photoelectric, enenzuzo yokonga ingxenye yefayibha.

I-single-fiber bidirectional optical fiber transceiver iyidivayisi yokuguqula isithombe kagesi esebenzisa ubuchwepheshe be-wavelength division multiplexing ukuze ithumele futhi yamukele idatha ku-fiber optical, futhi iguqule amasignali kagesi wenethiwekhi namasignali optical. I-single-fiber bidirectional optical fibre transceivers isidume kakhulu eminyakeni yamuva. Inzuzo ukuthi ingagcina ingxenye yefiber optical. Alikho izinga elihlangene lamazwe ngamazwe lokuntuleka kwengxenye yefiber optical. Imikhiqizo ekhiqizwa abakhiqizi abahlukahlukene ngokuvamile iyahambisana futhi inozinzo olubi kakhulu kunemikhiqizo ye-dual-fiber. Njengamanje, ama-transceivers e-fiber optic emakethe asabuswa yimikhiqizo ye-fiber ekabili.

Uyini umehluko phakathiI-single-fiber ye-single-fiber kanye nama-transceivers optical wemodi eyodwa ye-dual-fiber?

Imodi eminingi yemodi eyodwa incike kukhebuli yokubona, i-single-fiber dual-fiber isho ukudluliswa kwefayibha ewumgogodla owodwa noma ukudluliswa kwefayibha enezingqikithi ezimbili; Imodi eyodwa ibhekisela ekusetshenzisweni kwezintambo ze-optical zemodi eyodwa, ama-transceivers e-fiber eyodwa asebenzisa i-core eyodwa kuphela, zombili iziphetho Zombili zixhunywe kulo mgogodla, futhi ama-transceivers emikhawulweni yomibili asebenzisa ama-wavevel optical ahlukene, ngakho-ke amasignali optical angadluliselwa umgogodla owodwa. I-dual-fiber transceiver isebenzisa ama-cores amabili, enye eyokuthumela nenye yokwamukela, enye iphethelo iyadlulisa kanti enye kufanele ifakwe embotsheni eyamukelayo, okungukuthi, iziphetho ezimbili kufanele ziwele.

Ekusetshenzisweni okukhethekile kwemodi eyodwa kanye nemodi ekabili, inani lemodi eminingi liphezulu kunelemodi eyodwa, ikakhulukazi kububanzi bezintambo obungaphansi kuka-500m, imodi eminingi ingavele ihlangane, nakuba ukusebenza kungasebenzi kahle. njengemodi eyodwa. Imodi eyodwa isetshenziswa ezindaweni ezingaphezu kwama-500m noma ezindaweni ezinezidingo zomkhawulokudonsa ophezulu, ikakhulukazi ezinhlelweni zokusebenza zenkambu emikhulu njengezinga lebhizinisi. Ngoba ukuzinza nokusebenza kweamamojula we-fiber opticalzingcono kakhulu kunama-transceivers, kuzinhlelo zokusebenza zemodi eyodwa ezinezidingo eziphezulu zokusebenza, izinkampani ezimbalwa zisebenzisa ama-transceivers, kodwa zisebenzisa ngokuqondile amamojula esikhundleni.

Ifayibha eyodwa kanye nefayibha ekabili ngokuvamile inamachweba amabili, futhi amachweba amabili efayibha ekabili asondelene. Amakwe ngo-TX kanye ne-RX, eyodwa yokuthumela neyodwa yokwamukela, eziqokiwe; amachweba amabili efayibha eyodwa ngokuvamile i-P1, i-P2 ikhombisa ukuthi zombili izimbobo zingathumela futhi zamukele ngokuhlukana, okungukuthi, imbobo eyodwa isetshenziselwa ukuqedela ukuthumela nokwamukela, ngakho ibizwa ngokuthi i-fiber eyodwa. Ama-transceiver optical TX kanye ne-RX amele ukwamukela nokudlulisa. Kunezinhlobo ezimbili zama-transceiver optical: eyodwa iyimodi eyodwa kanti enye iyimodi ekabili. Njengomgwaqo onemigqa yomzila owodwa kuphela, ithrafikhi ingase ibe nesiminyaminya. Uma kuwulayini wemigqa emibili, izoba bushelelezi kakhulu, ngakho-ke kusobala ukuthi ama-transceiver anemodi ekabili azinzile kangcono.

I-fiber eyodwa isho ukuthi i-fiber eyodwa kuphela esetshenziselwa ukuxhuma ama-transceiver amabili. I-dual fiber ivame kakhulu futhi idinga imicu emibili, kanti intengo yefayibha 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 ama-multi-mode esuswa, kusenezinhlelo zokusebenza eziningi ekuqapheni nasekudluliseleni amabanga amafushane ngenxa yenani eliphansi. Ama-transceiver anemodi eminingi ahambisana namafiber optical anemodi eminingi, kanti imodi eyodwa kanye nemodi eyodwa zihambisana. Azikwazi ukuxutshwa.
