Product Details

The FieldSmart FDH PON Cabinet is the complete solution for managing up to 864 port distribution fibers for an outside plant FTTx PON application. Integrated into the cabinet design is the 12 port Clearview® Cassette, providing multiple cabinet configurations and allowing the service provider to align the investment in capital equipment to the turn- up of revenue-generating circuits.

The FieldSmart FDH 144-Port PON Cabinet incorporates a modular design, allowing the provider to repair or replace a damaged cabinet, without disrupting existing service. Cabinet includes a new pyramid shaped roof/solar shield and venting ports, providing additional protection for deployed fiber. Mounting options include pole mounted or pad/vault mounted with either a 4” or 12” (101.60 mm or 304.80 mm) riser.
