Chithunzi Chodziwika cha Singlemode Fiber- G.657A2 Singlemode Fiber

Singlemode Fiber- G.657A2 Singlemode Fiber Wasin Fujikura

Kufotokozera Kwachidule:

Nanjing Wasin Fujikura ya G.657A2 single mode fiber ili ndi mawonekedwe opindika bwino, makamaka omwe amagwiritsidwa ntchito mu netiweki ya FTTH. Yopangidwa molingana ndi muyezo wapamwamba kwambiri, magwiridwe antchito abwino kwambiri. ITU-TGB/T9771 ndiye muyezo watsopano. Wasin Fujikura imatha kupereka mainchesi a 180um, 200um, 400um fiber, kulandira mainchesi osinthidwa malinga ndi zosowa za makasitomala.
