A New Standard in Optimized Bend Performance and Reliable Low Loss Transmission.

Overview

AllWave® FLEX ZWP Single-Mode Fiber is the first Zero Water Peak (ZWP) G.652D fiber to offer optimized bend performance for Fiber-to-the-Home (FTTX), enterprise networks, or any application where small bend diameters may be encountered. Fully compliant to the new ITU-T G.657 Class A specification, AllWave® FLEX Fiber is completely compatible with all conventional single-mode fibers.

Product Description

AllWave® FLEX ZWP Fiber maintains very low bending loss across the full spectrum of wavelengths from 1260 to 1625 nm, while ensuring long-term fiber strength and reliability. It can be coiled into a 10 mm radius loop with < 0.5 dB incurred loss at 1625 nm and < 0.2 dB incurred loss at 1550 nm - five times better bend performance than conventional single-mode and leading Low Water Peak (LWP) fibers.

Features/Benefits:
  • Saves space, time, and money through improved bend performance, even for L-Band wavelengths up to 1625 nm: added loss < 0.5 dB (1625 nm) and < 0.2 dB (1550 nm) at 10 mm radius
  • Easier to install, handle, and store in space-constrained applications such as FTTX and premises networks
  • Bend optimized design for tight, low loss bends without risking fiber strength and long-term reliability
  • Tight geometry for very low splice loss and improved connectorization performance with G.652D embedded base
  • Fully compatible with all conventional single-mode fiber international standards including G.657 Class A and G.652D
  • Zero Water Peak fiber provides a 50% increase in usable optical spectrum enabling 16-channel CWDM and DWDM support


Applications:

AllWave® FLEX ZWP Fiber provides outstanding bend performance and design freedom for fiber management systems in:
  • FTTX
  • The central office
  • High power applications
  • Analog video
  • Microcables
  • Drop cables
  • Closures
  • Field management/storage apparatus located throughout the network
  • At the customer premises
  • Any application with transmission speeds of 40 Gb/s and beyond
