Questions about Toslink's

I'm going to install a new rack at my Dad's house some time this week. As such, i'm going to re-wire his system, which is a 2 channel / HT combo. Due to the large quantity of components involved, i would like to keep things as orderly as possible. As such, i'm trying to keep all the cables just long enough to do point to point wiring. I'll be building most of the interconnects and power cords, so that isn't a problem. What is a problem are the Toslink's that i need.

With that in mind, does anyone know if there is a drawback to running very short Toslink's ? I need one cable in specific that would be about 20" long. This is equivalent to a half meter ( give or take ). Since i can't find any commercial Toslink's at this length, i was wondering if it just isn't a common length or if there is a problem with going this short ? I've found a company that will build me Toslink's of whatever length i want, but before doing so, i just want to verify that this is okay. Obviously, i'd rather do my homework now than spend my money and find out later.

Since i've got your attention, is there anything such as a Toslink switchbox ? If so, does anybody know of one that works well and doesn't cost a fortune ? I would only need two inputs and one output.

Thanks for any and all help. When it comes to this stuff, i'm clueless : ) Sean

El: The splitter / switchbox is now a moot point. I just looked at the device that i was trying to hook up and it has four different digital inputs ( two coax, two optical ) that are switch selectable from the device itself. Can't ask for more than that.

Other than that, the reading that i did about optical splitters showed a VERY substantial loss in signal. Being the technical geek that i am, settling for something that i know will work but is known to be WAY less than optimum is not something that i like doing. Sean

FYI....The "typical" loss for a fiber optic termination/connection is on the order of 2dB. Two of them, so as to insert a switch means 4dB. When you factor in the loss of the switch itself you will end up near the 6dB to be expected from a splitter. (I assume that the splitter would be made with long legs so as to avoid need for extra terminations).
