Fiber Optic Products

The FieldSmart Hub Collapse Cabinet (HCC) is designed for the cable operator looking to separate their passive infrastructure from the electronics without the need for a traditional, and expensive, standard hub architecture.  The HCC provides a centralized location within a service provider’s network that houses both fiber terminations and optical components, eliminating the need for a physical “hub” location, thereby saving land, maintenance and permitting expenses. Service providers can realize increased revenue by collapsing multiple locations into one centralized service point.

Hub collapse environments allow the passive architecture to be placed in the most craftfriendly place for circuit and wavelength allocation and associated moves, adds, and changes (MAC) work - on the ground - and separates the critical active components protected in the node such as Cisco's O-Hub platform or Aurora V-Hub. Clearfield’s Hub Collapse Cabinet provides a centralized location that will accommodate both optical components and fiber terminations, making it an ideal solution for service providers looking to maximize the existing fibers within their network. With its small footprint (16”L x 16”W x 32”H), real-estate costs can be minimized with a multiple variety of mounting options (pole, pad, or vault mount). Fiber management is centralized and protected from environmental concerns. Designed to accommodate up to 120 fiber terminations using the Clearfield Cassette, the HCC cabinet also allows for up to 32 LGX compatible CWDM/DWDM modules to utilize existing optical components in the network. Fiber management and designation has been designed into the HCC cabinet for ease of use and accessibility.
