沃爾核材(002130.SZ):正在開展下一代448G高速通信線的預研工作
格隆匯7月30日丨沃爾核材(002130.SZ)在投資者互動平台表示,當前224G高速通信線的主流技術方案為物理髮泡技術和實心材料技術,公司憑此兩項技術方案開發的224G高速通信線已經過全球領先客户嚴格的認證審核,並且已經大批量交貨。 物理髮泡與藕芯結構具有不同的特點,物理髮泡是把惰性氣體如氮氣通過加壓混合方式,做成均勻密閉的微小氣孔的發泡材料,要求設備精密、操作技術高,藕芯結構是通過擠出機模具特殊結構,做出縱向通孔結構,這種結構在使用過程中,很容易潮氣進入通孔內引起介電常數增大,引起電信號衰減,影響傳輸速度不穩定;同時藕芯通孔結構在彎折變形時,通孔內空氣可以自由流動,引起壓縮變形,影響介電常數的穩定,對比物理髮泡的密封氣泡,氣泡內惰性氣體卻不容易流動,彎折時變形比較小,潮氣不容易進入密閉微孔內,影響介電常數輕微,使產品更穩定。 公司正在開展下一代448G高速通信線的預研工作。
