Lapho amaphrojekthi amanje abuthakathaka ehlangabezana nokudluliswa kwebanga elide, i-fiber optics ivame ukusetshenziswa. Ngenxa yokuthi ibanga lokudlulisela le-fiber optical lide kakhulu, ngokuvamile, ibanga lokudlulisela le-fiber yemodi eyodwa lingaphezu kwamakhilomitha angu-10, futhi ibanga lokudlulisela le-multi-mode fiber lingafinyelela kumakhilomitha angu-2.
Kumanethiwekhi e-fiber optic, sivame ukusebenzisa ama-transceiver e-fiber optic. Ngakho-ke, ungawaxhuma kanjani ama-fiber optic transceivers? Ake sibheke ndawonye.
Okokuqala, indima ye-fiber optic transceivers
① I-optical fibre transceiver inganweba ibanga lokudlulisela le-Ethernet futhi inwebe irediyasi yokukhava ye-Ethernet.
② I-optical fibre transceiver canshintshaphakathi kuka-10M, 100M noma 1000M Ethernet isixhumi esibonakalayo sikagesi nesixhumi esibonakalayo esibonakalayo.
③ Ukusebenzisa i-fiber optic transceivers ukwakha inethiwekhi kungasindisa ukutshalwa kwezimali kwenethiwekhi.
④ Ama-transceivers efiber optical enza ukuxhumana phakathi kwamaseva, abaphindayo, amahabhu, amatheminali namatheminali kusheshe.
⑤ I-optical fibre transceiver ine-microprocessor kanye nesixhumi esibonakalayo sokuxilonga, esingahlinzeka ngolwazi oluhlukahlukene lokusebenza kwesixhumanisi sedatha.
Okwesibili, iyiphi i-transceiver enayo futhi ithola yiphi?
Lapho usebenzisa ama-optical fibre transceiver, abangani abaningi bazobhekana nemibuzo enjengale:
1.Ingabe ama-optical fibre transceivers kufanele asetshenziswe ngababili?
2.Ingabe i-optical fibre transceiver ihlukaniswe yaba eyodwa yokwamukela neyokudlulisela? Noma ingabe ama-transceiver optical amabili kuphela angasetshenziswa njengepheya?
3. Uma ama-transceiver e-fiber optical kufanele asetshenziswe ngababili, ingabe kuyadingeka ukuthi abe uhlobo olufanayo kanye nemodeli? Noma ingabe amabhrendi angasetshenziswa ngokuhlanganiswa?
Impendulo: Ama-transceivers e-fiber optical ngokuvamile asetshenziswa ngababili njengamadivayisi okuguqula isithombe kagesi, kodwa kungenzeka futhi ukubhanqa ama-transceivers e-fiber optic ne-fiber.amaswishi, i-fiber optic transceivers kanye nama-transceivers e-SFP. Empeleni, inqobo nje uma ubude begagasi be-optical transmission bufana Ifomethi ye-encapsulation yesiginali iyafana futhi zombili zisekela iphrothokholi ethile ukuze kuzuzwe ukuxhumana kwe-fiber optical.
Ngokuvamile, i-dual-fiber yemodi eyodwa (imicu emibili iyadingeka ekuxhumaneni okuvamile) ama-transceivers awahlukaniswanga ekugcineni kokudlulisela kanye nesiphetho sokwamukela, futhi angasetshenziswa inqobo nje uma evela ngamabili.
I-transceiver ene-fiber eyodwa kuphela (ifayibha eyodwa iyadingeka ekuxhumaneni okuvamile) ezoba nesiphetho sokudlulisa kanye nesiphetho sokwamukela.
Ngamanye amazwi, amanani ahlukene (i-100M ne-Gigabit) namaza amaza ahlukene (1310nm no-1300nm) awakwazi ukuxhumana. Ngaphezu kwalokho, ngisho noma i-fiber transceiver eyodwa kanye ne-fiber ekabili yomkhiqizo ofanayo kubhanqiwe, akunakwenzeka ukuxhumana. Ukusebenzisana.
Ngakho umbuzo uwukuthi, yini i-fiber transceiver eyodwa futhi iyini i-dual fiber transceiver? Uyini umehluko phakathi kwabo?
Iyini i-single-fiber transceiver? Iyini i-dual-fiber transceiver?
I-transceiver ye-fiber eyodwa ibhekisela kukhebuli yokubona yemodi eyodwa. I-transceiver ene-fiber eyodwa isebenzisa umgogodla owodwa kuphela futhi iziphetho zombili zixhumeke kulo mgogodla. Ama-transceiver emikhawulweni yomibili asebenzisa amaza okukhanya ahlukene, ngakho-ke angadluliselwa ngesignali eyodwa yokukhanya.
I-transceiver ene-dual-fiber isebenzisa ama-cores amabili, eyodwa eyokudlulisela neyodwa yokwamukela, futhi isiphetho esisodwa kufanele sifakwe kwesinye isiphetho, futhi iziphetho ezimbili kufanele zeqe.
1.Single fiber transceiver
I-transceiver ye-fiber eyodwa kufanele isebenzise kokubili umsebenzi wokudlulisa kanye nomsebenzi wokwamukela. Isebenzisa ubuchwepheshe be-wavelength division multiplexing ukuze idlulise futhi yamukele amasiginali amabili okukhanya anamaza ahlukene e-wavelength ku-fiber optical eyodwa.
Ngakho-ke, i-transceiver ye-single-fiber yemodi eyodwa idluliselwa nge-fiber optical core, ngakho ukukhanya okudlulisayo nokwamukelayo kudluliselwa nge-fiber core ngesikhathi esifanayo. Kulokhu, ukuze kuzuzwe ukuxhumana okuvamile, amaza okukhanya amabili kufanele asetshenziselwe ukuhlukanisa.
Ngakho-ke, imojula ye-optical ye-transceiver ye-single-fiber ye-fiber ine-wavelengths emibili yokukhanya okukhishiwe, ngokuvamile i-1310nm / 1550nm. Ngale ndlela, kunomehluko phakathi kweziphetho ezimbili zepheya lama-transceivers:
I-transceiver ekugcineni idlulisa i-1310nm futhi ithola i-1550nm.
Esinye isiphetho sikhipha i-1550nm futhi sithola i-1310nm.
Ngakho-ke kulula kubasebenzisi ukuhlukanisa, futhi ngokuvamile basebenzise izinhlamvu esikhundleni.
I-A-terminal (1310nm / 1550nm) kanye ne-B-terminal (1550nm / 1310nm) ivele.
Abasebenzisi kufanele basebenzise ukubhanqa kwe-AB, hhayi ukuxhumana kwe-AA noma kwe-BB.
Ukuphela kwe-AB kusetshenziselwa kuphela ama-transceivers e-fiber optic eyodwa.
2.I-dual fiber transceiver
I-dual-fiber transceiver inembobo ye-TX (imbobo yokudlulisa) kanye nembobo ye-RX (imbobo eyamukelayo). Womabili amachweba adlulisa nge-wavelength efanayo ye-1310nm, futhi ukwamukelwa nakho kuyi-1310nm. Ngakho-ke, imicu emibili ye-optical ehambisanayo esetshenziswa kuzintambo ixhumekile.
3. Ungahlukanisa kanjani i-fiber transceiver eyodwa ku-dual fiber transceiver?
Njengamanje kunezindlela ezimbili zokuhlukanisa ama-transceiver e-fiber eyodwa kuma-dual-fiber transceivers.
①Uma i-transceiver ebonakalayo ishumekwe ngemojula ye-optical, i-transceiver ebonakalayo ihlukaniswa ibe i-transceiver ye-fiber eyodwa kanye ne-dual-fiber transceiver ngokuya ngenani lama-cores we-jumper optical fiber exhunyiwe. Ukulandelana kwe-optical fiber jumper exhunywe kusidluliseli se-fiber eyodwa (kwesokudla) kuwumgogodla we-fiber, onesibopho sakho kokubili ukudlulisa nokwamukela idatha; I-linearity ingama-cores amabili. Omunye umongo unesibopho sokudlulisa idatha kanti omunye umongo unesibopho sokwamukela idatha.
②Lapho i-transceiver ye-fiber optical ingenayo i-module optical egxilile, kuyadingeka ukuhlukanisa phakathi kwe-fiber transceiver eyodwa kanye ne-transceiver ye-fiber kabili ngokusho kwe-module optical efakiwe. Uma i-single-fiber bidirectional optical module ifakwe ku-transceiver fiber optical, okungukuthi, isikhombimsebenzisi siwuhlobo olulula, i-transceiver ye-fiber optical iyi-transceiver ye-fiber eyodwa (isithombe esifanele); lapho i-dual-fiber bidirectional optical module ifakwe ku-transceiver fiber optical, Okusho ukuthi, lapho isixhumi esibonakalayo siwuhlobo lwe-duplex, le-transceiver iyi-dual-fiber transceiver (isithombe esingakwesokunxele).
Okwesine, inkomba kanye nokuxhumeka kwe-transceiver ye-fiber optical
1.Inkomba ye-optical fiber transceiver
Ngenkomba ye-optical fibre transceiver, sinendatshana edlule enikelwe kulokhu okuqukethwe.
Lapha siphinde sivakashele ngesithombe ukuze sikucacise.
2.Uxhumano lwe-Fiber optic transceiver
