The ABB Bailey NTCF01 Infi 90 Fiber Optic Termination Unit is used to terminate and organize fiber optic connections within an ABB Bailey Infi 90 control system. It provides the interface between the fiber optic communication path and the associated control-system hardware.
In an Infi 90 installation, the NTCF01 is suited to communication arrangements where fiber optic transmission is used between control-system equipment. The termination unit helps organize the fiber connections within the cabinet and provides a defined point for installation, inspection, and maintenance.
For example, in a large process-control plant, fiber optic links may be routed between separated control cabinets or system sections to reduce the effect of electrical interference over long communication paths. The NTCF01 can be incorporated into this type of Infi 90 fiber communication arrangement.
During replacement work, technicians should verify the complete NTCF01 model, existing fiber routing, connection assignments, and associated Infi 90 communication hardware before disconnecting the installed unit.

The NTCF01 provides the physical termination interface for fiber optic communication connections associated with the Infi 90 system.
Infi 90 Communication Equipment → NTCF01 → Fiber Optic Link → Remote Infi 90 Equipment
The communication equipment sends and receives data through the fiber optic path. The termination unit provides the connection point where the fiber link is organized and connected to the associated system hardware.
Fiber optic communication is particularly useful in installations where control cabinets are separated by significant distances or where electrical noise could interfere with conventional communication wiring.
Typical communication functions may involve:
The NTCF01 itself does not execute control logic; it forms part of the physical communication connection used by the Infi 90 system.
The NTCF01 operates at the fiber optic communication interface layer of an ABB Bailey Infi 90 architecture.

The NTCF01 is an Infi 90 Fiber Optic Termination Unit used to organize and terminate fiber optic communication connections associated with the control system.
Fiber optic links can be useful when communication must travel between separated control-system areas or through environments with significant electrical interference. They also allow communication paths to be physically separated from conventional electrical signal wiring.
The existing fiber connection arrangement, associated communication equipment, connector identification, and cable routing should be documented before the unit is disconnected. This helps prevent incorrect fiber reconnection during replacement.
The fiber path should be checked from the Infi 90 communication equipment through the NTCF01 and fiber cable to the remote equipment. Connector condition, fiber continuity, connection assignments, and communication diagnostics should be reviewed to identify the location of the fault.
