FutureGuide®-SR15E Bending-loss Insensitive Single-Mode Fiber (ITU-T G.657.A1)

FTTH (Fiber to the Home) is the hottest topic in Today's telecommunication industry. For compact storage in tight space of a building, Fujikura has developed FutureGuide®-SR15E, allowing smaller fiber bending radius compared to the standard G652 fiber without reducing the signal. FutureGuide®-SR15E is suitable for aerial drop cable, indoor cable, patch cord or any FTTx application cable.

Read full description



  • For optical cord and cable for FTTH / LAN / Premises

  • Allowable bending radius is 15mm, being half (1/2) in radius & one-fourth (1/4) in size, compared with that of 30mm of conventional SM fiber

  • Highly reliable low water peak characteristic

  • Good spliceability with conventional SM/LWP Fiber
