Fiber Optic Products

Utilizing the Clearview® Blue Cassette, the FieldSmart ZoneBox provides a POLAN sub floor or ceiling mount enclosure that easily scales from 12 to 144 ports. Preloaded for patch only, patch and splice or MPO plug-and-play applications, the ZoneBox can be shipped loaded with your industry standard adapter of choice, while supporting all cable constructions for inside plant environments. The FieldSmart ZoneBox is a solid enclosure designed to protect fiber terminations from damage. Access is provided by a hinged cover for ceiling applications or removable cover that pulls off for sub floor applications. When used for PON applications, the FieldSmart ZoneBox supports the ability to house up to six splitter modules, including a single 1 x 32 splitter. The FieldSmart ZoneBox provides a swinging bulkhead for rear-access to the cassettes and protects sub-unit slack storage.

Designed from conception to provide fast, easy fiber jumper routing and ease of access to all circuits, the FieldSmart ZoneBox system is craft-friendly, keeping the installer’s needs for quick deployment, intuitive use and ease of maintenance as the top priorities.
