The two source records do not describe the same underlying event. The older topic covers East Tender Optoelectronics (6588.TW), a Taiwan-listed optical communication filter maker that returned to profit in first-half 2026 with NT$9.21 million in net profit on NT$184 million of revenue as telecom and datacom filter demand improved. The newer topic covers Wavelength Opto-Electronic, which reported first-half 2026 net profit of CNY 28.85 million on CNY 243 million of revenue, driven by demand for optical components used in semiconductor equipment. Because the companies, currencies, business segments and reported results differ, the records should not be merged as one event.
