Rugged indoor terminals provide secure, flexible fiber interconnect facilities to multiple customers

Charles multi-compartment Fiber Building Terminals (CFBT-D3) provide a rugged indoor cabinet solution ideally suited to cell sites, campuses, strip malls, business parks and other environments where multiple customers require high-capacity fiber bandwidth for wireless backhaul, private networks or data and video broadband services. The CFBT-D3 is designed as a demarcation terminal with lockable internal chambers that separate access between the service provider and up to three different subscribers. 

With multiple built-in SC/APC or SC/UPC adapter bulkheads, CFBT-D3 cabinets facilitate fast and easy provisioning of fiber services to the end customers’ fiber multiplexing equipment. Fiber drops can be turned up, moved or disconnected on an “as needed” basis, giving telecom service providers added flexibility in their efforts to provide broadband voice, data and video services to customers whose bandwidth requirements may change seasonally or due to major events.


CFBT-D3 cabinets are ideally suited to multi-dwelling units (MDU), cellsites, campuses, strip malls, business parks and other applications where the multiple customers require high-capacity fiber bandwidth for wireless backhaul, private networks or data and video broadband services. Their convenient form factor saves space in basements, huts, telecom equipment closets and other indoor locations.
