TOSLINK Optical Signal Splitting?



If I signal split an optical signal does it halve the signal strength or does it otherwise degrade the signal?
Any recommendations on how I should do it?

Does anyone have any thoughts on the original question?

optical is pretty much the worst digital interface.  There isn't a good "Y-cable" solution.  However, if you google for "spdif splitter", there are several products that will split and re-transmit the optical cable signal.  Optical cable is a 1-way digital signal, so there is no worry about hand-shaking or communication.  Two items that seem to have good results:
- J-Tech Digital Premium Quality SPDIF TOSLINK Digital Optical Audio 1x3 Splitter  ($21.98 from Amazon)

- Metra ethereal AS-1X3TSPLIT ($29.99 from Crutchfield)
