Ftth fiber cable Single Mode G.657 A-E , indoor drop cable access network fiber unit bend insensitive single mode optical outdoor cable.
The quality and technical indicators of 2 Core single mode fiber fully comply with the requirements of ITU-T G.652 and its accessories. And comply with the relevant technical specifications of IEC, especially IEC 60793 and IEC 60794 parts. At the same time, it meets the technical requirements of the corresponding national standards. It also meets the Ministry of Information Industry standard YD/T 901-2009 for optical cables. Raw materials should meet the requirements of relevant national standards. It means the outer sheath should comply with YD/T 1485-2006, Ointment and fiber paste should comply with YD/T 839.3, the steel strip should comply with YD/T723.3, etc.
The G 654 FTTH Optical Fiber has two characteristics of low attenuation and large effective area. After that, the G654 2 core single mode fiber used for Marine cable communication was mainly optimized around attenuation and effective area. And gradually developed into four subcategories: A / B / C / D.
