FutureGuide®-BIS-B ITU-T G.657.A2 (Superior Bend Insensitive Fiber + ITU-T G.652.D compliance)

Product code : BEFSOE

Just like FutureGuide®-SR15E, FutureGuide®-BIS-B is also designed for compact storage in tight space of a building, but allowing even smaller fiber bending radius than FutureGuide®-SR15E fiber with excellent bending loss performance. FutureGuide®-BIS-B is suitable for aerial drop cable, indoor cable, patch cord or any FTTx application cable.


  • For optical cord and cable for FTTH / LAN / Premises
  • Highly reliable low water peak characteristic
  • Excellent spliceability with conventional SM/LWP Fiber
