1550nm Multimode Dual Stage Optical Isolator

  • Wavelength: 1550nm or Custom Wavelength
  • Handling Power: 500mW or Custom Handling Power
  • Fiber Type: Multi-mode Fiber
Product Details

  The 1550nm Multimode Dual Stage Optical Isolator is an in-line pigtailed miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It features high isolation and low insertion loss. The optical isolators are commonly used to protect lasers or amplifiers against back-reflected light. This fiber optic isolator could be built with 50/125um or 62.5/125um multimode fiber.
