Product Overview
The ABB Bailey NTCF21 Infi 90 Fiber Optic Termination Unit is a fiber optic termination component used within ABB Bailey Infi 90 control-system installations. It provides a structured termination point for fiber optic communication connections and forms part of the physical communication infrastructure between associated Infi 90 system equipment.
In an Infi 90 control cabinet, the NTCF21 can be used where fiber optic links connect distributed control-system sections. The termination arrangement keeps the optical connections organized and accessible, which is particularly useful in large control cabinets where multiple communication paths need to be identified during commissioning or maintenance.
In a process plant, for example, an Infi 90 control section may exchange information with equipment located in another cabinet or system area through a fiber optic link. The NTCF21 can be incorporated into this type of communication arrangement, with the connected optical path carrying system communication data between the two locations.
For replacement work, technicians should verify the complete NTCF21 model, existing fiber connections, connector assignments, cable routing, and associated Infi 90 communication equipment before disconnecting the installed unit.

Working Principle
The NTCF21 provides the physical termination interface for fiber optic communication connections associated with the Infi 90 system.
Infi 90 Communication Equipment → NTCF21 → Fiber Optic Cable → Remote Infi 90 Equipment
The associated communication equipment exchanges system data through the fiber optic path. The NTCF21 provides the termination point where the optical connection is organized within the control-system installation.
Fiber optic communication can be used between separated control cabinets, distributed system sections, or other areas where an optical communication path is appropriate. The termination unit keeps these connections structured so that technicians can identify and service the communication path more easily.
Typical information exchanged through the communication architecture may include:
- Control-system data
- Process information
- Equipment status
- System diagnostic information
- Communication data between distributed system sections
The NTCF21 functions as part of the physical communication interface rather than executing control logic or independently processing the Infi 90 application.
Role in an Infi 90 Control Architecture
The NTCF21 operates at the fiber optic communication interface layer of an ABB Bailey Infi 90 control architecture.

Installation and Maintenance
- Confirm the complete NTCF21 model before installation or replacement.
- Identify the associated Infi 90 communication equipment.
- Record the existing fiber connection arrangement before disconnecting the unit.
- Label each fiber connection according to the system documentation.
- Inspect fiber connectors for contamination, damage, or improper seating.
- Check the fiber cable routing for excessive bending or mechanical stress.
- Verify the cabinet mounting arrangement before installing the replacement unit.
- Install the NTCF21 in the approved control-system location.
- Reconnect the fiber connections according to the documented arrangement.
- Confirm that all connectors are fully seated.
- Check communication between the local and remote Infi 90 equipment.
- Record the final fiber connection arrangement for future maintenance.
When troubleshooting a communication problem, check the NTCF21 termination, fiber connectors, cable path, associated communication equipment, and remote Infi 90 equipment individually to locate the interruption.

Technical FAQs
What is the ABB Bailey NTCF21 used for?
The NTCF21 is an Infi 90 Fiber Optic Termination Unit used to terminate and organize fiber optic communication connections associated with the control-system architecture.
How does the NTCF21 fit into an Infi 90 communication path?
The unit sits within the physical fiber communication path between associated Infi 90 communication equipment and the fiber optic cable. It provides the termination point rather than performing the control-system communication processing itself.
What should be checked before replacing an NTCF21?
The existing fiber connection assignments, cable routing, connector condition, associated communication equipment, and system documentation should be checked before removing the unit. The original connection arrangement should be recorded for reinstallation.
What are the first areas to inspect when an NTCF21 communication path fails?
Check the fiber connectors and termination points first, followed by the fiber cable path and associated communication equipment. Local and remote Infi 90 communication diagnostics can then be used to determine whether the problem is at the termination, optical link, or system-equipment level.
