PM Isolator & WDM Hybri

PM Isolator & WDM Hybrid is a special component which integrates an optical isolator and a WDM optical coupler together within a compact package. The isolator plus WDM coupler is especially useful for doped optical fiber amplifier design and applications. Two types of WDM couplers are available: 1480nm/1550nm and 980nm/1550nm. The signal at 1550nm window firstly goes through the isolator and then is combined with the pumping laser power at the WDM coupler. Previous stage of optical circuits are protected due to the optical isolation. Signal stage and dual stage isolation are available.

This product reduces the overall cost and simplifies the system structure, while providing improved performance and reliability.
