EPFU Fiber Cable/FU/ABF/Fiber Unit

able Section Design

1. Fiber     2. Resin     3. Fillers     4. Groove     5. HDPE sheath

 

Feature

• Smaller diameter
• Frees up capital to expand network and client base
• Network design flexibility
• 5/3.5mm microduct suitable
• Easy to upgrade
• Greater blowing distance
• Fiber: G.G652D, G.657A1, G.657A2

 

Standards

• Unless otherwise specified in this specification, all requirements shall be mainly in accordance with the following standard specifications.
• Optical fiber:ITU-T G.651、G.652、G.655、G.657 IEC 60793-2-10、IEC 60793-2-50
• Optical Cable:IEC 60794-1-2、IEC 60794-5
• Note: It is recommended that the structure of 2 fibers unit consist of 2 filled fibers, for it is proved that this structure is better in the blowing performance and the fiber separability than that of one with zero or one filled fiber
