YSD3 with Sea&Sea TTL converter-Will it work with fiber optics or have to use Sync cords?

[UnderwaterThunder]

I have a stupid question but need a bit of clarity. I Have a Sea & Sea Flash trigger.If I change to YS converter will I have TTL capability using Fiber Optic cable or will I have to use Electronic sync cord?

The specs for Sea & Sea Optical YS Converter/C2 state:

A compact unit that converts the camera's TTL signal to a light signal. The converter can be mounted on the camera's accessory shoe and can be connected to (a) SEA&SEA strobe(s) with Fiber-Optic Cable(s) (*). TTL and manual modes can be switched by pushing the mode switch on the housing.

Therefore, fiber optic cables are the only connections you can use. It does not support wired sync.
