波長可調諧濾波器OTF-930是一款偏振無關的80nm可調濾波器。Santec的"Linear Sliding"技術使得在PDL，帶寬和插入損耗等光學特性恒定不變的情況下，進行準確持續的波長調諧。OTF-930能實現非常低的插入損耗。OTF-930利用串聯的形式增加濾波隔離來實現最小的插損增益。OTF-930的十幾款型號基本覆蓋了絕大部分的光纖應用。

• 80nm可調范圍
• 低插入損耗
• 低PDL（＜0.1dB）&PMD（＜0.1ps）覆蓋所有可調范圍
• 0.01nm波長分辨率
• 使用LabView軟件驅動，支持GP-IB
• ASE噪音抑制
• 波長選頻
• 波長可調諧激光器：相干光源
