I-G.652D I-fiber optical yemodi eyodwa (B1.3)-Ibanga B

I-G.652D I-Optical fiber yemodi eyodwa (B1.3)-Ibanga B Isithombe Esifakiwe

Incazelo emfushane:

Isiqongo samanzi aphansi esingahlakazisi i-fiber yemodi eyodwa ilungele uhlelo lokudlulisela lwebhendi egcwele engu-1280nm ~ 1625nm, engagcini nje ngokugcina ukuhlakazeka okuphansi kwebhendi yendabuko engu-1310nm, kodwa futhi inokulahlekelwa okuphansi ku-1383nm, okwenza ibhendi ye-E. (1360nm ~ 1460nm) isetshenziswa ngokugcwele. Ukulahlekelwa nokuhlakazeka kwebhendi yonke kusuka ku-1260nm kuya ku-1625nm kuthuthukisiwe, futhi ukulahlekelwa ukugoba kwe-wavelength ye-1625nm kuncishisiwe, okunikeza izinsiza zomkhawulokudonsa wenethiwekhi yomgogodla, i-MAN kanye nenethiwekhi yokufinyelela.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici Zomkhiqizo

● Inkomba yefayibha yemodi eyodwa enconyelwe i-ITU-T G.652D kanye ne-IEC B1.3 yefayibha enconyiwe ye-IEC B1.3;

● Ukusebenza okuhle kakhulu kokubona, kunganelisa ukusebenza kahle okuphezulu kwe-DWDM kanye nokudluliswa kwezidingo zesistimu ye-CWDM;

● Usayizi wejiyomethri omuhle kakhulu, wokuqinisekisa ukushiselwa kokulahlekelwa okuphansi nokusebenza kokuvala okuphezulu;

● I-coefficient ephansi ye-PMD, yanelisa uhlelo lokudlulisela lwebanga elide nokusebenza kahle okuphezulu.

Ukukhiqizwa Komkhiqizo

Isicelo somkhiqizo

1. Ifanele zonke izinhlobo zesakhiwo sekhebula le-fiber optic: uhlobo lweshubhu ye-beam emaphakathi, uhlobo oluxhumeke lwesendlalelo somkhono oxekethile, uhlobo lwamathambo, isakhiwo sekhebula le-fiber optic;

2. Izicelo ze-fiber optical zihlanganisa: izinhlelo ze-fiber optical ezidinga ukulahlekelwa okuphansi kanye nomkhawulokudonsa ophezulu, njengokuxhumana okude, imigqa ye-trunk, i-loop feeders, imigqa yokusabalalisa kanye ne-cable TV, njll., efanelekile ikakhulukazi i-1383nm band coarse wavelength division multiplexing ( I-CWDM), i-multiplexing ye-wavelength division multiplexing (i-DWDM) kanye nokusetshenziswa okukhethekile kwemvelo okuhlukahlukene (isb. Ikhebula le-OPGW elifaka umbani elifaka umbani, ikhebula le-ADSS optical, njll.), i-fiber optical ngokusebenzisa okokucwenga okukhethekile okuphulukisayo kanye nenqubo yokuhlanganisa nangemva kokucubungula, ukuze inokusebenza okuphezulu kakhulu kuzakhiwo zemishini kanye nokusebenza kwemvelo kokushisa okuphezulu.
