FieldShield FLEXdrop Flexible Fiber Drop Cable

Clearfield’s FieldShield FLEXdrop cable provides the most flexible option of our FieldShield product line. The OSP-rated PVDF jacketing allows for transition of FLEXdrop from the OSP environment directly into the inside plant, with the added benefit of being UL listed for plenum applications. FLEXdrop is either pulled or pushed through microduct at turn-up, maximizing installation efficiency. In the event of a later fiber cut, the fiber can be easily pulled from microduct. The duct is then repaired and a new FieldShield Pushable Assembly is pushed or pulled through the microduct for a fast and cost-effective restoration. Options for riser-rated applications are also available.

Product Details

FieldShield FLEXdrop has more flexibility than standard FieldShield Optical Cable making it ideal for shorter drops where more handling and slack storage may be required. Whether it’s used indoor or outdoor, the flexibility of the jacket allows for deployment with reduced jacket memory and decreases the risk of kinking. While FLEXdrop is typically used in conjunction with FieldShield Microduct solutions, in some applications, it can be stapled directly to walls and ceilings or used on building wrap applications securing with crown T18 staples.

Connector options for this product include FieldShield SC Pushable Connectors or FieldShield MPO Pushable Connector.
