Optimized bend performance for ocean applications


AllWave® FLEX Single-Mode Ocean Fiber is the first Zero Water Peak (ZWP) fiber to offer outstanding bend performance for ocean applications. It is an excellent choice for ocean riser applications or for cable designs that require a highly bend-resistant fiber. AllWave® FLEX Ocean Fiber meets the requirements of G.654C.

Product Description

AllWave® FLEX ZWP Ocean Fiber maintains very low bending loss while ensuring long-term fiber strength and reliability. It can be coiled into a 20 mm diameter loop with < 0.5 dB incurred loss at 1625 nm and < 0.2 dB incurred loss at 1550 nm - five times better bending performance than conventional single-mode and leading low water peak (LWP) fibers.

  • Improved bend performance up to 1625 nm: added loss < 0.5 dB (1625 nm) and < 0.2 dB (1550 nm) at 10 mm radius
  • Bend-optimized design without risking fiber strength and long-term reliability
  • Tight geometry for very low splice loss
  • Fully compatible with single-mode fiber international standard G.654C
  • A patented manufacturing technology that permanently removes the water peak defect for low optical loss across the entire spectrum from 1260 to 1625 nm
