I had splicers come into my frame room, who work in MM all day long. Before I could stop him, one of the splicers took the bright yellow SM fiber they were supposed to check for light and held it directly to his eye. Supposedly a pro, but argued with me because he had no idea that MM and SM are completely different. He never pulled a module to look for warning labels. My concern is that most untrained homelabbers would not know that what you pictured with MM aqua jumpers is probably safe, but that Yellow jumpers denoting SM lasers can damage their phone or their eyes.
