Product details
Overview
The FT-1064-78 merges a high power optical isolator and a bandpass filter into one TGG-based 1064 nm device. The isolator stage blocks back-reflected light to protect the laser source, while the bandpass stage passes the wanted wavelength band and rejects out-of-band energy such as amplified spontaneous emission. Combining both functions in a single package reduces part count and board space in compact fiber optical systems. The design targets high power handling together with high isolation, high extinction ratio and high return loss. Pass bandwidth, stop bandwidth, isolation, insertion loss and power ratings are listed in the specification table.
