https://www.naddod.com/products/18224.html that's the 2018 200g standard at over 1000$ a meter. Can't find public pricing but the new 400/800 gb/s are more expensive!

That price is 95% the endpoints, 5% the cable. The fibre in between the QSFP adapters on the end is practically free.

The 30m pricing is almost the same: https://www.naddod.com/products/18231.html

     1m    $1,087
    10m    $1,124
    30m    $1,196
A bit of linear regression on the back of the envelope yields $3.76 per meter for the fibre, and $560 as the cost per QSFP adapter.
