Intambo yokubona ye-Aipu-waton GJYXCH kanye ne-GJYXFCH iyikhebula yokudonsa engaphandle ye-FTTH. Ikhebula le-optical liqukethe i-1 ~ 4 ye-silica optical fibers ene-coating, engaba i-G657A1 noma i-G652D. Imicu yokubona eyenziwe ngomklamo ofanayo, impahla kanye nenqubo izosetshenziswa kuqoqo elifanayo lemikhiqizo, futhi imicu yokubona izobekwa phakathi nendawo yekhebula le-optical. I-optical fiber coating layer ingaba nombala. Umbala wesendlalelo esinemibala uzoba luhlaza okwesibhakabhaka, owolintshi, oluhlaza okotshani, onsundu, ompunga, omhlophe, obomvu, omnyama, ophuzi, onsomi, opinki noma o-cyan ngokuhambisana ne-GB 6995.2, futhi i-fiber eyodwa ingaba umbala wemvelo.
