Module optique ya DWDM ni iki?

Ikoranabuhanga rya Dense Wavelength Division Multiplexing (DWDM) irashobora gukoreshwa mubice bitandukanye byurusobe rwitumanaho, harimo imiyoboro miremire miremire, imiyoboro ya metero nkuru (MAN), imiyoboro yo guturamo, hamwe numuyoboro waho (LAN).

Muri iyi porogaramu, cyane cyane ABAGABO, uburyo buto-bushobora gucomeka (SFP) nubundi bwoko bwa optique modules akenshi bishyirwa mubintu byinshi-byuzuye.Niyo mpamvu abantu bategereje cyane transvers ya DWDM optique.Iyi nyigisho izakubwira kubyerekeye incamake ya moderi ya optique ya DWDM, ikanakumenyesha kuri Beiyi Fibercom (WWW.F-TONE.COM) DWDM optique module ibisubizo.

Module optique ya DWDM ni iki?

Nkuko izina ryayo ribitubwira, module ya DWDM ni module optique ihuza ikoranabuhanga rya DWDM.Moderi ya optique ya DWDM ikoresha uburebure butandukanye kugirango igwize ibimenyetso byinshi bya optique muri fibre optique, kandi iki gikorwa ntigikoresha imbaraga.Izi moderi optique zagenewe ubushobozi-buke, kohereza intera ndende, igipimo gishobora kugera kuri 10GBPS, naho intera ikora irashobora kugera kuri 120KM.Muri icyo gihe, module ya optique ya DWDM yateguwe hakurikijwe amasezerano menshi (MSA) kugirango harebwe uburyo butandukanye bwibikoresho byurusobekerane.10G DWDM optique modules ishyigikira ESCON, ATM, Umuyoboro wa Fibre na 10 Gigabit Ethernet (10GBE) kuri buri cyambu.Moderi ya optique ya DWDM kumasoko mubisanzwe irimo: DWDM SFP, DWDM SFP +, DWDM XFP, DWDM X2 na DWDM XENPAK optique, nibindi.

Imikorere nihame ryakazi rya DWDM optique module

Igikorwa cyibanze nihame ryakazi rya moderi ya optique ya DWDM ni kimwe nizindi moderi optique, ihindura ibimenyetso byamashanyarazi mubimenyetso bya optique, hanyuma bigahindura ibimenyetso bya optique mubimenyetso byamashanyarazi.Nyamara, moderi ya optique ya DWDM yagenewe porogaramu ya DWDM, kandi birakwiye ko tuvuga ko ifite imiterere n'imikorere byayo.Ugereranije na moderi ya optique ya CWDM igabanya (CWDM) module ya optique, module ya optique ya DWDM yagenewe fibre yuburyo bumwe, kandi nkuko byasobanuwe neza na ITU-T, iri mumurongo wa DWDM uri hagati ya 1528.38 kugeza 1563.86NM (umuyoboro wa 17 kugeza kuri 1563.86NM) umuyoboro 61).ikore hagati yuburebure.Ikoreshwa mugukoresha ibikoresho bya rezo ya DWDM yo kugera mumijyi hamwe numuyoboro wibanze.Iza ifite SFP 20-pin ihuza imikorere ishyushye-swappable imikorere.Igice cyayo cyohereza ikoresha DWDM nyinshi ya kwant ya DFB ya laser, ikaba ari laser yo mu cyiciro cya 1 yujuje ubuziranenge mpuzamahanga IEC-60825.Mubyongeyeho, moderi ya optique ya DWDM itangwa nabaguzi benshi yujuje ubuziranenge bwa SFF-8472.Udushya tugezweho muri sisitemu yo kohereza DWDM harimo gucomeka, guhuza optique ishoboye gukora kumiyoboro 40 cyangwa 80.Ibi byagezweho bigabanya cyane gukenera modules zitandukanye mugihe urwego rwuzuye rwuburebure rushobora gukoreshwa gusa nibikoresho bike byacomeka hano na hano.

Itondekanya rya DWDM optique module

Mubisanzwe, iyo tuvuze kuri moderi ya optique ya DWDM, twerekeza kuri Gigabit cyangwa 10 Gigabit DWDM optique.Ukurikije uburyo butandukanye bwo gupakira, modul ya optique ya DWDM irashobora kugabanywa muburyo butanu.Nibo: DWDM SFP, DWDM SFP +, DWDM XFP, DWDM X2, na modul optique ya DWDM XENPAK.
