FieldSmart Fiber Scalability Center (FSC) Hub Collapse Cabinet (HCC)

The FieldSmart Hub Collapse Cabinet (HCC) provides a centralized location within a service provider’s network that houses both fiber terminations and optical components. This eliminates the need for a physical “hub” location, thereby saving land, maintenance and permitting expenses. Service providers increase revenue by collapsing multiple locations into one centralized service point.

Product Details

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. Hub collapse environments allow passive architecture to be placed in the most craft-friendly place for circuit and wavelength allocation and associated MAC (moves, adds, and changes) work - on the ground. Providing up to 120-fiber terminations using the Clearview® Cassette and up to 32 LGX compatible CWDM/ DWDM modules, the FieldSmart Hub Collapse Cabinet (HCC) separates critical active components typically protected in the node, such as Cisco’s O-Hub platform or Aurora V-Hub, and allows existing optical components to be reused throughout the network.

Clearfield’s Hub Collapse Cabinet (HCC) provides a centralized location that will accommodate both optical components and fiber terminations, making it an ideal solution for service providers looking to maximize existing fibers within their network. With a small footprint (32” H x 16.78” W x 16.9” D - 812.80 mm x 1426.21 mm x 429.26 mm), real estate costs can be minimized with a variety of mounting options (pole, pad or vault mount).
