Can't say I've ever encountered a laptop limited to 1TB hard drive before. It's usually over 2TB that causes issues.
Anyway, so long as your optical drives uses a SATA connector this won't be an issue. I done the exact same thing with an older laptop when SSD prices were much higher. 64GB SSD in the normal hard drive bay and a 500GB HDD in the optical drive. Worked a treat.
One thing to look out for is your optical drive might not use SATA3. Since the higher bandwidth isn't required manufacturers often use cheaper SATA2 interfaces for the optical drive. This could limit your SSD.
