Outdoor Fiber Distribution Hub for Passive Optical Networks (GPON/EPON)

Charles Fiber Interconnect Terminal (CFIT) Hubs

CFIT Hubs (CFIT-H) provide fiber distribution to up to 96 subscribers from a compact, outdoor terminal. CFIT-H have been designed with flexibility in mind and support fusion, pre-terminated and field terminated feed and drop fibers. These PON terminals have space for up to three 1x32 splitters for incremental growth. They are commonly mounted to an exterior wall of a multi-dwelling unit (MDU) for distribution to centralized or distributed Optical Network Terminals (ONT).

Everything about the interior of the CFIT-HS (standard hub) is designed with the technician in mind. Cable entry locations are positioned at the top and bottom of the terminal, allowing flexible placement of feed and distribution cables. Fiber bend radius controls and routing guides ensure cable management and proper slack storage. A splice tray basket secures hinged splice trays that are individually accessible without disturbing previously spliced trays. The splice tray basket is itself removable for pre-terminated and field terminated applications. A hinged bulkhead increases the technician’s working area for greater access to the SC adapter panels. The bulkhead includes nine rows of 12-count adapters. The top row is dedicated to feed fibers and features shuttered adapters. The remaining eight rows create up to 96 drop locations. Three splitter slots are easily accessible. Charles 1x32 Passive Splitter Modules (CFSM) are available with optimized pigtail lengths.

CFIT-H are constructed from powder-coated aluminum that is both durable and lightweight. The unit can be quickly installed by a single technician. The main entrance door is secured with a low-profile, 216-tool quarter turn lock and padlock hasp for additional access control. Both internal and external bond locations are provided. Removable mounting rails allow units to be mounted to walls, H-frames or posts.

A compact hub (CFIT-HC) option is available for applications of up to 48 subscribers, ideal for small sized MDU.


CFIT Hubs provide PON fiber distribution for up to 96 subscribers at multi-user locations, with grow-as-you-go scalability.
