Optimized Bend Performance and Reliable Low Loss Transmission for In-Building, Central Office and Cabinet Applications

Overview


AllWave® FLEX+ ZWP Single-Mode Fiber is the first Zero Water Peak (ZWP) fiber that meets and exceeds both ITU-T G.657.A2 and G.652.D specifications. This 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 Fiber-to-the-Home (FTTH), cell sites, enterprise networks, or any application where small bend diameters may be encountered.

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 7.5 mm radius loop with < 0.5 dB incurred loss at 1550 nm and < 1.0 dB incurred loss at 1625 nm.

Features/Benefits:
  • Fully compliant with the ITU G.657.A2 standard; also meets all requirements of G.657.B2 and G.652.D
  • Designed for in-building, cabinet, cell site, and central office applications
  • 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
  • Excellent fusion splice performance using standard recipes
  • Zero Water Peak fiber provides a 40% increase in usable optical spectrum enabling 18-channel CWDM support and much greater DWDM capacity
Applications:

AllWave FLEX+ Fiber provides outstanding bend performance and design freedom for fiber management systems in:
  • FTTX - Multi-dwelling Units (MDUs)
  • FTTX - In building applications
  • FTTX - Drop cables
  • The central office
  • High power applications
  • Closures
  • At the customer premises
  • Any application with transmission speeds of 40 Gb/s and beyond
