  • Product Detail


Enhanced Performance Fiber Unit (EPFU) is small size, light weight, enhanced surface outer sheath fiber unit designed for blowing into micro tube bundles by air flow. The outer thermoplastic layer provides a high level of protection and excellent installation properties.


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


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
