Reliable Bend-Optimized Performance for Smaller Diameter, Higher Density Cable Applications


OFS offers AllWave® FLEX+ Bend-Optimized Single-Mode Fiber with a 200 µm coating diameter for use in cables with higher fiber counts per tube and in microcables where cable diameters must be minimized. The fibers offer all the other performance advantages and 30-year reliability of standard AllWave FLEX+ products.

Product Description

200 µm AllWave FLEX+ Fiber
offers enhanced bend performance ideally suited for in-building and connectivity applications and full compatibility and compliance with the installed base of conventional G.652.D single-mode fibers. It is an excellent choice for higher density cables for Access networks, high-density Fiber-to-the-Home (FTTH) applications, cell sites, enterprise networks, or any application where high fiber count lower diameter cable may be encountered. It meets and exceeds both ITU-T G.657.A2 and G.652.D specifications.

  • Bend optimized design for tight, low loss bends without risking fiber strength and long-term reliability
  • 36% less area than conventional 250 µm coated fiber enabling smaller diameter cables and a greater number of fibers per tube
  • Ideally suited for high fiber count cables and microcables where cable diameter needs to be minimized
  • Zero Water Peak fiber provides a 50 percent increase in usable optical spectrum, enabling 16-channel CWDM and DWDM support
  • Proof-tested to 100 kpsi to improve long term reliability and simplify cabling

200 µm AllWave FLEX+ Fiber provides outstanding bend performance and design freedom for fiber management systems in:
  • FTTX
  • High count fiber cables
  • High power applications
  • Microcables
  • Closures
  • At the customer premises
  • Any application with transmission speeds of 40 Gb/s and beyond
