FieldShield StrongFiber is a durable high tensile strength fiber when compared to other fibers of its size. It is suitable for both indoor and outdoor environments. Manufactured with premium bend-insensitive fiber, FieldShield StrongFiber offers high tensile strength to resist damage to the fiber during installation in the FieldShield Microducts. When terminated with a FieldShield Pullable Connector, the FieldShield StrongFiber can be quickly deployed, and in turn, reduces installation time drastically.

FieldShield StrongFiber Deploy Reel

The FieldShield StrongFiber Deploy Reel is a 4.5”x 1” spool, designed to hold up to 300 feet of StrongFiber, with integrated bulkhead and pre-mated adapter that can easily be mounted into a small form factor fiber management element of choice. The small form factor of the 900um fiber makes slack storage minimal and easy to accommodate, while the exceptional pull strength of StrongFiber makes it craft-friendly and easy for the technician to handle without fear of fiber damage. With less cable weight and, therefore, less co-efficient of friction (COF), installations are more timely and with minimal friction as the cable is pulled through bends and turns throughout the microduct route path. Reducing the size requirements of the access point (above or below grade) provides a more aesthetically pleasing solution in the neighborhood.
