Umfanekiso oBonisiweyo weFiber yeMode enye- G.657A2

I-Fiber yeMode enye- G.657A2 I-Fiber yeMode enye- Wasin Fujikura

Inkcazo emfutshane:

I-Nanjing Wasin Fujikura ye-G.657A2 single mode fiber ineempawu ezingcono zokugoba, ezisetyenziswa kakhulu kwinethiwekhi ye-FTTH. Ivelisa ngokwemigangatho ephezulu, ukusebenza kugqwesile, i-ITU-TGB/T9771 yeyona migangatho intsha. I-Wasin Fujikura inokubonelela ngobubanzi be-180um, 200um, 400um fiber, yamkela ububanzi obulungiselelwe wena ngokweemfuno zabathengi.
