Professional Testing Center
In order to ensure product performance and stability, all products are to be tested in NADDOD Test Center. For example, transceiver tests include spectrum, eye diagram, bit error rate, aging, high-and-low temperature cycles, end-face, etc.; fiber cables tests include insertion & return loss, 3D interference, end-face, MPO polarity, etc.; switch tests include L2 & L3 features (e.g. BGP, OSFP, VXLAN), management functions (e.g. SNMP, Sflow), reliability (e.g. LACP, VRRP, MLAG), security (e.g. 802.1x, DDOS, ACL), performance, stability, interoperability, etc. All products must be tested to meet or excel the standard requirements, or they will be returned to the production lines for improvement till they are.
