اپتوکوپلر

[بندانگشتی|شماتیک یک اپتوکوپلر که فرستندهٔ آن یک [ال‌ای‌دی و گیرندهٔ آن یک فوتوترانزیستور است.]]

**جداساز نوری**، **اُپتوایزولاتور** ، **ایزوله‌گر نوری،** یا **اُپتوکوپلر** ، یک مجموعه فرستنده-گیرندهٔ نوری است که در آن، سیگنال الکتریکی به نور تبدیل‌ شده و می‌تابد و در سوی دیگر، یک حس‌گر، نور را دوباره به سیگنال الکتریکی تبدیل می‌کند. برای نمونه، می‌توان آن‌را در مدارهای کنترلی به‌کار برد و ولتاژ یک طرف مدار را از ولتاژ طرف دیگر (به ویژه زمین‌های دو طرف را) جدا کرد.
