Single mode single and double fiber isolator
This single-mode optical isolator provides effective protection against back reflections in 1310nm and 1550nm wavelength systems. Available in both single and double stage configurations, it offers high isolation, low insertion loss, and excellent return loss, with an epoxy-free optical path ensuring reliability.
Ideal for CATV systems, fiber amplifiers, telecommunications, and test applications, the isolator is compatible with SMF-28 fiber and supports various connector types and fiber lengths for flexible integration.
