Vesala NanoSonde VMS3-33 for Locating Blocked Microducts
During fiber optic network installation, microducts must provide a clear path for the cable. However, a blockage, deformation, or other duct issue can prevent successful installation.
The Vesala NanoSonde VMS3-33 helps technicians locate the problematic point. First, the operator prepares the transmitter with the appropriate accessories. Next, the system is propelled through the microduct using compressed air, following Vesala’s safety instructions.
If the transmitter stops at an obstruction, the technician uses a compatible 33 kHz receiver to locate the signal from the surface. This makes it possible to identify the approximate blockage area and plan a more targeted intervention.
Key Advantages of the Vesala NanoSonde VMS3-33
This NanoSonde combines compact dimensions with practical operation. More specifically, it offers the following advantages:
- Diameter 2.8 mm: Allows inspection of very small microducts.
- 33 kHz Frequency: Provides compatibility with suitable locating receivers.
- Microduct Inspection: Supports internal diameters starting from 3.5 mm.
- Blockage Detection: Helps identify the point where the transmitter stops.
- Low Weight: Weighs just 1 g including the battery.
- Battery Life: Provides approximately 6 hours of operation at 20°C.
- Easy to Transport: Its compact size makes it easy to use in the field.
- Professional Application: Suitable for FTTH and FTTx infrastructure inspections.
Therefore, the NanoSonde is a specialized choice for field crews that require more precise fault location in fiber optic microducts.

Compatibility with the Vesala CL43 Compact Locator
The Vesala NanoSonde VMS3-33 transmits a 33 kHz signal. Therefore, the technician needs a compatible receiver that supports this frequency in order to locate the transmitter.
The VESALA Compact Locator CL43-PA is a compatible locating solution. The receiver can detect the NanoSonde signal and help identify its position.
In addition, the CL43 is suitable for professional locating tasks involving cables, sondes, and underground routes. This allows a field crew to use the same receiver for multiple applications, provided that the appropriate transmitters are available.
Microduct Passability Testing Before Fiber Optic Installation
Microduct passability testing is an important step before installing a fiber optic cable. First, the crew must confirm that the microduct allows the appropriate test equipment to pass through.
With the Vesala NanoSonde VMS3-33, the technician can perform passability testing in very small microducts. If the transmitter travels through the entire route, the result provides a useful indication of passability for the specific test diameter.
Conversely, if the transmitter stops, the operator can locate its signal from the surface using a suitable receiver. This helps avoid blind troubleshooting and reduces unnecessary intervention.

Vesala VMS3-33 vs. MicroSonde MPL6-33: What’s the Difference?
Vesala offers different sonde models for ducts of various diameters. Therefore, the choice depends mainly on the internal diameter of the duct and the method used to propel the sonde.
The VMS3-33 has a diameter of 2.8 mm and supports applications in ducts with an internal diameter starting from 3.5 mm. In contrast, the MPL6-33 has a diameter of 6.4 mm and requires a duct with an internal diameter of at least 8 mm.
For larger microducts, also see the VESALA MICROSONDE MPL6-33 6.4mm 33kHz on the ARCTOS Solutions online store.
Important Instructions for Use
The Vesala NanoSonde VMS3-33 is intended for professional use. Therefore, technicians should follow the Vesala manual and select accessories that match the diameter of the microduct.
When propelling the sonde with compressed air, always use a suitable shock absorber and the specified collection system at the outlet. In addition, observe the pressure and speed limits and use the appropriate personal protective equipment.
The transmitter has an IP40 protection rating. Therefore, do not use it in microducts containing water or in applications that exceed the manufacturer’s specified limits.
Frequently Asked Questions About the Vesala NanoSonde VMS3-33
What is the Vesala NanoSonde VMS3-33?
It is a 2.8 mm diameter active 33 kHz transmitter. Technicians use it to test the passability of small microducts and locate blocked routes in fiber optic infrastructure.
What microduct diameters is it suitable for?
The NanoSonde supports microducts with an internal diameter starting from 3.5 mm. In addition, with the appropriate accessories, it can be used with 4 mm and 6 mm microducts, as well as other compatible diameters specified by the manufacturer.
