Co-Gain J04H Blue

You know, I'm not even mad these don't have real names, the serial numbers are fine. So we finally found the manufacturer of these weird opticals, Co-Gain/Xuda, and even found a website and taobao storefront. So of course I had to buy all their OEM level stuff. I'm pretty sure these are the same as the Dareu Optical blue but the product pics weren't good enough to tell and I couldn't possibly take a chance on missing a new 4th blue optical for a board I don't have could I?
