Overview
The ISO in-line isolator is a fiber-coupled passive component from the Luna passive components group (formerly General Photonics) that lets light pass only in the forward direction. It comes in polarization-insensitive single-mode (SM) and polarization-maintaining (PM) versions, in single-stage or double-stage designs, for 1550 nm, 1310 nm or 1064 nm.
The isolators are compact and built to work reliably in a wide range of environments. Their small size, low loss and low back reflection make them suitable for integration into many fiber optic systems.
NoTail version
The NoTail version (NISO) has no external pigtails, which avoids the problems pigtails can cause. Its short optical path makes it useful for ultra-short pulse and interferometric applications. NoTail versions are convenient for laboratory use and storage.
The manufacturer lists this product as discontinued.
