AllWave FLEX 200 µm Fiber

AllWave FLEX 200 µm Optical Fiber supports higher density and lower diameter cables, providing outstanding macrobend and microbend performance for Access, Fiber-to-the-Home (FTTH), enterprise networks, or any application where small bend diameters may be encountered.

This G.657.A1 fiber maintains very low bending loss across the full usable spectrum of wavelengths from 1260 to 1625 nm. 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 LWP fibers.

Features And Benefits

  • 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% 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
  • Ultra-low Polarization Mode Dispersion (PMD) enables speed and distance upgrades

Applications

  • 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

Overview
