I would say we're a pure optical contract manufacturer — we build other companies' designs, no products of our own. That's not a gap; it's why customers hand us the work. They don't want us competing with them. We differentiate on relationships, capacity, execution, let's say, not scarce technology. Benchmark, Celestica, InnoLight, Jabil, Sanmina, Venture — they're the competition. Some customers also build in-house. Advanced optical packaging and precision manufacturing services. That's the whole business.
