Fiber optic sync cable for INON strobes to Nauticam and 10Bar digital camera housing Panasonic LX5, TZ10, GH1, etc. This fiber-optic cable resists bending and has improved light-conducting efficiency. The OSC-I-NA consists of optical fiber to transmit built-in flash light to trigger an external strobe more reliably comparing to conventional wireless slave system, even in severe condition like just under the surface or with backlight.
