G.657A1 Ifayibha egobisayo yemodi eyodwa Isithombe Esifakiwe

Incazelo emfushane:

Umkhiqizo wamukela ubuchwepheshe obuthuthukisiwe bokwenziwa kwenduku yokwenziwa kwe-fiber prefabricated prefabricated, obungakwazi ukulawula okuqukethwe kwe-OH- kwe-fiber prefabricated rod ibe sezingeni eliphansi kakhulu, ngakho-ke umkhiqizo une-coefficient yokuncishiswa okuhle kakhulu kanye nesiqongo samanzi esiphansi, ukusebenza kahle kakhulu kokudlulisela. Umkhiqizo ungaqinisekisa irediyasi encane yokugoba kuyilapho ihambisana ngokugcwele nenethiwekhi ye-G.652D, ukuze ifayibha ikwazi ukuhlangabezana ngokugcwele nezimfuneko zezintambo ze-FTTH.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izici Zomkhiqizo

● I-attenuation coefficient enhle kakhulu kanye nenani elincane lamanzi.

● "O - E - S - C - L yawo wonke ukuthunyelwa kwebhendi.

● Ukulahlekelwa ukugoba okuphansi.

● Amandla aphezulu okukhathala.

● Ihambisana ngokugcwele nenethiwekhi ye-G.652D.

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 optics zihlanganisa: izinhlelo ze-fiber optic ezidinga ukulahlekelwa okuphansi kanye nomkhawulokudonsa ophezulu; Ifaneleka ngokukhethekile ikhebula elithambile le-MAN, idivayisi encane ye-fiber optical, i-optical fiber coupler nezinye izinhlelo zokusebenza ezikhethekile;

3. Lolu hlobo lwe-fiber lufanele ama-O, E, S, C no-L bands (okungukuthi, kusukela ku-1260 kuya ku-1625nm). Lolu hlobo lwefiber optical luhambisana ngokugcwele ne-G.652D fiber. Ukucaciswa kokulahleka kokugoba kanye nesikhala esihlangene kuthuthukiswa kakhulu, kokubili ukuthuthukisa ukuxhumana;

4. Ingakwazi ukusekela ukufakwa kwezinhlelo ezincane ze-half-diameter kanye nevolumu encane yokucubungula i-fiber optical eziteshini zamahhovisi ezokuxhumana kanye nezindawo zamakhasimende ezakhiweni zokuhlala nasezindlini zokuhlala ngabanye.
