The OptoRite CW4802 is
a 48X 16X 48X burner.
OptoRite is a manufacturer and has been in business a little over a year (since October 2001).
I don't know anything about the quality of this drive. It may be a good drive, but I would get the Liteon if I could since it's quality is known. Also, there is a lot of support available for Liteons on the forums and frequent firmware updates.
You may be on your own with the OptoRite, at least until enough of them are sold to get a user community going.
