Fiber optic cord vs electric sync cord

So I have decided to get an inon z240 strobe. Which type of sync cord is best? They are about the same price by the time you add up what is needed? I was told by one person that the fiber optic sync cord will allow you to use optical TTYL, is this true and how beneficial is it? I know the electric cord will not support TTYL since the housing is Ikelite and the strobe is Inon/

It's my understanding that whether you use a hard wired connection to your strobe or a fiber optic connection depends on the housing you're using, as some housings won't permit use of a fiber optic connection. In my case, I have to use hard wired connections to my Inon Z240s since I have a Subal housing. In your case, with your Ikelite housing, it appears you can use a fiber optic connection.

A fiber optic connection is generally preferable to a hard wired connection as there's less chance of a flood. In uw photography, the weakest point of the entire system is the hard wired connection to the strobe. With fiber optic, there's less chance of problems that are typical of a hard wired connection.

Some folks think TTL is very beneficial, others not so much. I personally don't use TTL and don't have a big problem with that. Others feel differently about it.

Hope that helps.
