What oversupply? Even in the lower end ranges that they're focusing on, Chinese pluggable makers like Innolight are still bottlenecked for 70-100mW ranges from ECOC channel checks. Cambridge wouldn't be going out financing suppliers with convertible loans for scarce laser capacity. Suppliers wouldn't be raising ASPs if there was overcapacity. Also not all CW lasers are the same. China is a ways away from from scaling UHP lasers needed for CPO, which is why there's still premiums given to $LITE, $COHR, $SIVE. $LITE lasers are sold out into 2029 and they're starting negotiations into 2030. I don't think anyone genuinely believes that China will flood the laser markets medium term, even both $LITE / $AAOI CEO said there was a difference between comments made and what they're actually seeing. From AOI on China: "of them, they are working maybe 70 mW or very few can really do 100 mW. For 300 mW laser, especially DWDM spec, we don't see that." "Not in the next two, three years, especially the demand is so big. Okay? Even combined AOI, Lumentum, Coherent, Broadcom all together, it's still very tough to meet the customer demand in the next few years" From Lumentum last month: "At least at the moment, we see no impact from any Chinese laser supply." But whenever markets want a correction people just blindly point to China with memory or optics while ignoring what's actually occurring with demand imbalances + LTAs spanning many years and constantly extending.
