DCM
色散補償卡

CDTrans-DCM闆是一(yī)種純無源光(guāng)器(qì)件(jiàn)，對标準G.652單模光(guāng)纖在C波段進行色散斜率補償，保證高(gāo)速信号經過長距傳輸後的信号質量，消除碼間幹擾，提升系統傳輸性能(néng)，實現長距、高(gāo)帶寬、大容量信号的傳輸，1550nm波長的色散範圍可以達到(dào)-2100至-10ps/nm，并可提供中心波長和色散有特殊要求的産品。與EDFA結合時，爲光(guāng)傳輸提供了一(yī)種簡單、可靠、經濟高(gāo) 效的長途傳輸解決方案，使信号在不進行再生(shēng)的情況下(xià)傳輸距離更遠。
