AllWave® FLEX+ Fiber - Zero Water Peak

Features And Benefits

Zero Water Peak fiber with 40% increase in usable spectrum enables 18-channel CWDM support and much greater DWDM capacity
Coiled into a 7.5 mm radius loop, fiber incurs losses of < 0.5 dB @ 1550 nm and < 1.0 dB @ 1625 nm
Tight geometric control for very low splice loss and improved connector performance
Ultra-low PMD for speed and distance upgrades
High-purity synthetic silica for long-term attenuation stability and mechanical reliability

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

Overview

AllWave FLEX+ Zero Water Peak (ZWP) Single-Mode Fiber is the industry’s first ZWP fiber that meets and exceeds both ITU-T G.657.A2 and G.652.D specifications. This bend-optimized fiber offers enhanced bend performance for tight, low loss bends without risking fiber strength and long-term reliability.

Product Description

While AllWave FLEX+ ZWP Fiber retains all the performance benefits of AllWave ZWP Fiber, it also provides very low bending loss across the full 1260 nm – 1625 wavelength range. This fiber’s macrobending and microbending loss improvements combine with its strength and reliability to help (1) allow more compact, intricate cabinet and enclosure designs; (2) protect against excessive loss from inadvertent fiber bends; and (3) reduce potential damage from cable flexing, pulling and crushing.

While AllWave FLEX+ ZWP Fiber provides twice the microbend protection of conventional single-mode fibers in high-stress and low-temperature environments, it is fully compatible and compliant with the embedded fiber base.
