The ABB Bailey NTCF03 Infi 90 Electric to Optical Termination Unit is used in Infi 90 control-system installations where an electrical communication connection interfaces with an optical communication path. It forms part of the communication termination arrangement between the electrical side of the system and the fiber optic side.
In an Infi 90 installation, the NTCF03 can be used where communication signals need to transition from electrical system wiring to an optical link. This arrangement is useful in distributed control installations where control cabinets or system sections are separated by distance or where electrical interference needs to be minimized along the communication path.
A typical plant application may involve an Infi 90 control cabinet communicating with another system section through fiber optic cabling. The NTCF03 provides the termination point for the electrical-to-optical interface, while the associated communication hardware handles the system data exchange.
For replacement work, technicians should verify the complete NTCF03 model, electrical connections, fiber connections, cable routing, and associated Infi 90 communication hardware before removing an existing unit.

The NTCF03 forms an interface between an electrical communication connection and an optical communication path within the Infi 90 system.
Infi 90 Electrical Communication → NTCF03 → Optical Communication Path → Remote Infi 90 Equipment
The electrical-side communication connection is brought to the termination unit, where the communication path transitions to the optical side of the system. The associated fiber optic link then carries the communication signal toward the remote system equipment.
This type of arrangement is useful when communication must pass between separated control-system sections without extending an electrical communication path through the entire installation.
Typical uses within the communication architecture include:
The NTCF03 functions as a termination and interface component; the associated Infi 90 communication equipment handles the actual control-system data processing.
The NTCF03 operates at the communication interface layer where an electrical communication path connects to an optical network segment.

The NTCF03 is an Infi 90 Electric to Optical Termination Unit used to interface an electrical communication connection with an optical communication path within the control-system architecture.
An electrical-to-optical interface allows communication to continue over fiber between separated system sections. This can be useful where long communication paths or electrically noisy plant environments make an optical connection preferable.
Both the electrical-side connection and optical-side connection should be documented before removal. Cable labels, connection assignments, fiber routing, and the associated Infi 90 communication equipment should also be recorded.
The communication path should be checked from the Infi 90 communication equipment through the electrical connection, NTCF03, fiber link, and remote communication equipment. Checking each section separately helps determine whether the fault is associated with the electrical connection, termination unit, fiber path, or remote equipment.
