AllWave® FLEX Max Optical Fiber

Features And Benefits

Full spectrum fiber with a 40% increase in usable optical spectrum enables 18-channel CWDM support and much greater DWDM capacity
Coiled into a 5 mm radius loop, fiber incurs losses of ≤ 0.10 dB @ 1550 nm and ≤ 0.25 dB @ 1625 nm
Fully complies with ITU-T G.657 B3 and G.652.D standard recommendations
Maintains extremely low bending loss across the entire optical spectrum
Helps improve drop cable performance in extreme high-stress and low temperature environments
Tight geometric control for very low splice loss and improved connector performance

Applications

AllWave FLEX Max Fiber provides outstanding performance and design freedom for fiber management systems in:

FTTH – Multi-dwelling Units (MDUs), in-building applications and drop cables
Central office
High power applications
Closures
At the customer premises

Overview

AllWave FLEX Max Single-Mode Fiber offers outstanding bend performance to a 5 mm radius for demanding applications. Compatible to and compliant with the installed base of conventional G.652.D single-mode fibers, this fiber is specifically designed for any situation where very small bend diameters may be encountered.

Product Description

AllWave FLEX Max Fiber minimizes bending loss, especially in applications where fiber bend radius may be unmanaged. In challenging conditions, this fiber protects the network against excessive loss from inadvertent bends and from cable flexing, pulling and crushing. AllWave FLEX Max Fiber’s bend performance also enables complex routing within even the most compact cabinet and enclosure designs.

The excellent macrobend performance of AllWave FLEX Max Fiber protects the fiber in high power applications such as those in central offices. This capability allows providers to reliably achieve significantly smaller bend diameters with up to 100 times lower loss than conventional single-mode fiber.
