2-12 Cores SM G657A2 EPFU Air Blown Fiber

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.

EPFU is supplied in pans of 2 kilometers as standard, but can be supplied in shorter or longer lengths on request. In addition, variants with different fiber numbers are possible. The EPFU is supplied in a sturdy pan, so that it can be transported without damage.

Fiber Type: ITU-T G.652.D/G.657A1/G.657A2, OM1/OM3/OM4 Fibers
