We've looked at these before a few years ago, when someone was selling them cut for red.
It was not a winning idea.
As for the listed advert Their specs don't add up.
9 dB of insertion loss per channel, for example, 3 dB is half your power gone, 9 dB means nearly 1/10th transmission.
While the directivity is excellent, the loss is huge.
If that is truly 900 u fiber, your looking at ~ 20-30 mm collimated beam diameter. Plus 8 expensive launch optical trains. Planter's spatial filtered red beats that.
I can get 8 to 12 single mode red diodes into a 200 uM or smaller fiber using free space optics at better then 90% coupling. I just need the better part of half a square meter of bench space and one custom curved mirror to do it.

I should have rented the space under my name for advertising.
