Sourcing 400G QSFP-DD from Guanglian Xuntong Technology Group Co., Ltd. - China Import Guide
Before ordering, confirm the specific variant of the 400G QSFP-DD module required for your fiber type and distance needs. Single-mode and multi-mode variants serve different applications, and the wrong choice could limit performance. Additionally, verify compatibility with your network equipment, particularly if you are using non-Cisco platforms.
Discuss logistics details such as lead time, which can vary depending on the module’s configuration and availability. Clarify Incoterms to determine shipping responsibilities, and agree on payment terms such as TT or LC. For high-volume orders, negotiate bulk pricing and packaging options to optimize shipping costs.
Quality checks should include validating the module’s compliance with IEEE 802.3bs and QSFP-DD MSA standards. Request test reports for parameters like optical power, receiver sensitivity, and bit error rate. Inspection upon delivery is advised, and for critical deployments, consider third-party testing to ensure the modules meet your network’s performance requirements.
