These isolators are the smallest in size but the highest in quality in the market. They are ruggedly built to function reliably in a wide variety of environments. The small size, polarization insensitivity, low loss, and low reflection combine to make these isolators ideal for integration in many fiber optic systems. We also offer the NoTail™ version to eliminate the dreadful headaches of pigtail handling. The short optical path (~ 7 cm) of the NoTail™ isolator is most desirable for ultra-short pulse and interferometric applications.
