Polarization Maintaining Fiber Optic PM Isolator & WDM Hybrid for ICT AI Computing
PM Isolator & WDM Hybrid
The PM Isolator & WDM Hybrid is a specialized component that integrates an optical isolator and a WDM optical coupler within a compact package. This isolator plus WDM coupler combination is particularly useful for doped optical fiber amplifier design and applications. Two types of WDM couplers are available: 1480nm/1550nm and 980nm/1550nm. The signal at the 1550nm window first passes through the isolator and then combines with the pumping laser power at the WDM coupler. Previous stages of optical circuits are protected due to optical isolation. Both single stage and dual stage isolation options are available.
This product reduces overall costs and simplifies system structure while providing improved performance and reliability.
