Abstract
德赢ac米兰官方合作伙伴 circulator is one of the key devices in 德赢ac米兰官方合作伙伴 add-drop modules (OADMs) used in wavelength-division multiplexing (WDM) technology, which finds applications in large-capacity long-haul telecommunications systems. A low-loss optical circulator has been developed to significantly improve OADM performance. Insertion loss for these modules is extremely low--less than 0.44dB at the operating temperature and wavelength range. High reliability and high power resistance are assured by fabrication techniques that use YAG welding for mechanical components, eliminating the use of adhesives in 德赢ac米兰官方合作伙伴 path.
