Recently got roughed up by the learning curve of adding fiber. Different SFP's and fiber sound different just like cables sound different. Some are thin and bright, others dark and muddy.
I have 2 suggestions, first find Finisar FTLF1324P2BTL 4gb Fiber Channel SFP Transceivers on ebay, second
for fiber https://www.mouser.com/ProductDetail/phoenix-contact/2989284/?qs=MfVUZiz0Pxb22RFH%252b7EEOg==&co...
However I am using one Finisar 1324 on the ER and a Finisar 1318 on a SOtM switch and prefer it to 2 1324's. It has a slightly fuller softer sound, maybe a little less detailed.
