mini-Single stage double stage isolator
This compact mini isolator offers high isolation and low insertion loss in a small form factor (Φ3.0×25mm). Designed for 1310nm, 1480nm, and 1550nm wavelengths, it provides reliable protection against back reflections with an epoxy-free optical path.
Ideal for CATV systems, fiber amplifiers, and telecommunication networks, the isolator is available in both single and double stage configurations. Compatible with SMF-28 fiber, it supports various connector types and fiber lengths for space-sensitive applications.
