I-Singlemode Fiber- G.657A2 I-Singlemode Fiber Isithombe Esifakiwe

I-Singlemode Fiber- G.657A2 I-Singlemode Fiber Wasin Fujikura

Incazelo emfushane:

I-Nanjing Wasin Fujikura ye-G.657A2 ifayibha yemodi eyodwa inesici sokugoba esingcono, esisetshenziswa kakhulu kunethiwekhi ye-FTTH. Khiqiza ngokwezinga eliphakeme kakhulu, ukusebenza kudlule i-ITU-TGB/T9771 izinga elisha kakhulu. I-Wasin Fujikura inganikeza ububanzi buka-180um, 200um, 400um fiber, yamukela ububanzi obungokwezifiso ngokwezidingo zamakhasimende.
