About the Sonic Heads
Sonic Heads are end-of-the-cable mounted semi-open shuttles used in conjuction with Cablejet to install very light and flexible fiber optic cables. It allows a slight tension force at the lead end of the cable to help keep the cable straight in the duct while allowing a large portion of the air flow to pass by so that the drag force can still act on the entire length of the cable. As the pressure builds behind the shuttle, a spring-loaded valve opens wider to limit the tension force and allow even more of the drag force to pass by. The Sonic Head has also shown to be a useful tool when installing some cables in corrugated duct, in that it slows sown the air flow and reduces turbulence caused by the duct corrugations.
