High-performance PM Fiber for CPOHigh-performance PM Fiber for CPO
Targeting high-density, highly integrated and highly stable co-packaged optics (CPO) applications, we offer a series of high-performance polarization-maintaining (PM) fibers for CPO. The series uses a mature and reliable Panda structure with symmetric, regular dual circular stress elements, delivering high birefringence, excellent grindability, low transmission loss, and high-precision, highly consistent geometric parameters that fully meet the stringent requirements of CPO precision packaging.
It covers the 1310 nm operating wavelength in two cladding diameters, 125 μm and 80 μm. The bend-resistant structure is optimized with a minimum bend radius of 5 mm, suiting the trend toward high-density integration and miniaturized packaging in optical networks, and providing a stable, reliable, high-performance optical transmission medium for CPO co-packaged optics.
