Otu ụdị eriri Fiber- G.657A2 Otu ụdị eriri Fiber Fujikura
Nanjing Wasin Fujikura nke eriri G.657A2 nwere njirimara mgbagọ ka mma, nke a na-ejikarị eme ihe na netwọk FTTH. Mmepụta dịka ọkọlọtọ kachasị elu si dị, arụmọrụ ya karịrị ọkọlọtọ kachasị ọhụrụ nke ITU-T\GB/T9771. Wasin Fujikura nwere ike inye dayameta nke eriri 180um, 200um, 400um, na-anabata dayameta ahaziri ahazi dịka ihe ndị ahịa chọrọ si dị.
