Fiber Applications
Thanks to its broad usable optical spectrum and outstanding attenuation performance, YOFC G652D Low Loss Single-mode Fiber is the optimum choice that supports various applications such as Ethernet, Internet Protocol (IP), Asychronous Transfer Mode (ATM), Synchronous Distribution Network (SDH) and Wavelength Division Multiplexing (WDM). YOFC G652D Low Loss Singlemode Fiber provides wider bandwidth and much lower signal attenuation for backbone, metropolitan area and access networks.
Product standards
YOFC G652D fibre complies with or even exceeds the ITU-T Recommendation G.652.D and the IEC 60793-2-50 type B1.3 Optical Fibre Specification.
