Duct sondes

Vesala produces the smallest sondes in the industry. Small sondes are especially intended for calibrating fiber optic microducts and locating their blockages e.g. before jetting fibers.

The probes create a magnetic field around themselves, which can be used to locate the probe from a cable route or underground. Often, the probes are used together with a push wire, which is used to deliver the probe to the blockage point in the route.

With a separate search device, the place in need of repair can be located on the surface of the earth. Below you will find our world famous probes and their accessories. Search devices for locating probes can be found in their own section.

NanoSonde MPL4-33, Ø4.6 mm, 33kHz

(0)

NanoSonde MPL4-33 is Vesala’s new, world’s tiniest active sonde for small underground ducts. It is only 4.6 mm in diameter so it is optimal for calibrating 6 mm (inner diameter) fiber optic ducts and to locate their blockages, dents and other problems. MPL4-33 is flexible in the middle so it can navigate tight duct curves down to 170 mm radius.

MicroSonde MPL6-33, Ø6.4 mm, 33kHz

(0)

MPL6-33 is a separate, very small size microduct transmitter sonde. It is intended to be used with the cable tracers and pipe locators using the 33kHz tracing frequency. It is especially suitable for tracing blockages of optical cable’s microducts or for tracing other small non-conductive pipes and sewers. MPL6-33’s diameter is only 6.4mm so it fits into...
