Optical ModuleBus Communication

The TK811V150 carries ModuleBus communication through a duplex plastic optical fiber path. Therefore, the communication link uses optical transmission rather than a copper electrical signal path.

The POF construction provides electrical isolation between connected nodes. In addition, the optical path does not form a conductive signal path for electromagnetic interference. Consequently, the cable can separate the communication medium from electrical noise sources associated with industrial control wiring.

The 15 m cable length defines the physical connection supplied by this model. Furthermore, the prefabricated construction reduces field termination work and preserves the specified connector arrangement.

For S800 installations, the cable functions as a physical ModuleBus interconnection component. However, the supplied data does not specify communication velocity, optical attenuation, wavelength, or receiver sensitivity, so these values should not be inferred from the model number.

Frequently Asked Questions (FAQ)

Q: Does the TK811V150 require an electrical power connection?

A: No. The TK811V150 is a passive optical cable and has no specified power consumption.

Q: What is the physical cable length?

A: The TK811V150 has a specified cable length of 15 m.

Q: Can the cable length or optical performance be extended by field splicing?

A: The supplied data identifies the product as a prefabricated cable. It does not specify field splicing procedures or permitted modifications. Therefore, installation should retain the supplied cable and connector configuration.

Field Installation Guidelines

1. Verify the complete ABB part number, 3BSC950107R3, before installation.
2. Confirm that both connected devices support the required optical ModuleBus interface.
3. Route the cable away from mechanical pinch points, sharp edges, and excessive bending.
4. Do not pull the cable by its optical connectors during installation.
5. Keep connector interfaces clean and protected from dust before mating.
6. Maintain the factory-installed connector configuration unless ABB documentation explicitly permits modification.
7. Avoid routing practices that place continuous mechanical stress on the fiber cable.
8. After installation, verify that both optical connectors are fully seated and mechanically latched.
9. If communication faults occur, inspect connector seating, cable routing, visible damage, and fiber continuity before replacing system hardware.
10. Do not assign an operating temperature, minimum bend radius, attenuation, or optical transmission limit unless the applicable ABB installation documentation specifies the value
