随着电信、移动、企业和数据中心网络融入云网络基础架构，对能够普遍适用的、高带宽和低成本光模块产品的需求开始爆发性成长。400G/200G QSFP-DD现在已经成为了云计算网络光互联解决方案的实际标准, 400G QSFP-DD较100G在某些情况下比较优势还非常明显。由于这一无可匹敌的性价比，所有业内企业都在迅速推出QSFP-DD产品。为了适应云计算，数据通信领域这一快速发展，芯科通信推出全系列QSFP-DD 产品 ：
未来3年数据中心内的400G高速光模块的几个技术和市场方向。
数据中心的几个首要需求是：1)接口密度(Port Density); 2) 功耗(Power Dissipation);3)成本(cost/gigabit)，通用说法是高接口密度，低功耗以及超低廉的价格(High
port density, low power dissipation, and extreme low cost)。
目前400GbE的主流接口，CFP8，OSFP，QSFP-DD和COBO，分别对应着几种不同的产业生态系统，芯科团队主要推出下列产品系列：
