PM (Polarization Maintaining) WDM (Wavelength Division Multiplexing) and isolator hybrid offer the best-integrated solution to fiber optic amplifier applications by combining more functions into a compact package. It provides a wide operating wavelength range, low cost and insertion loss, and high channel isolation, stability, and power handling capability. This article provides a comprehensive guide on PM WDM and isolator hybrid for fiber optic amplifier applications.
What is a PM WDM and Isolator Hybrid?
PM WDM and isolator hybrid is a device that combines filter WDM and isolator into a compact package. The device is built with Panda PM fiber or SMF-28e fiber and is available without or with connectors and single and dual-stage types.
Why PM WDM and Isolator Hybrid is Crucial for Fiber Optic Amplifier?
PM WDM and isolator hybrid combine or separate light at different wavelengths in a wide wavelength range. In other words, the device combines signal and pump wavelengths with very stable signal isolation (1550 nm). It can expand the capacity of a single fiber to achieve bidirectional communication that is widely used in Raman amplifiers and employs TFF(Thin Film Filter ) technology. The signal at the 1550nm window first goes through the isolator and then is combined with the pumping laser power at the WDM coupler. The previous stage of optical circuits is protected due to the optical isolation.
Features and Benefits
Here are some key features and benefits of using a PM WDM and isolator hybrid:
1. Low insertion loss and cost
2. Low polarization-dependent loss (PDL) and polarization mode dispersion (PMD)
3. High channel isolation, extinction ratio, and return loss
4. High reliability, stability, and power handling capability
5. Epoxy-free on the optical path and compact size
6. Wide operating wavelength range
Applications
PM WDM and isolator hybrid are used in fiber lasers, fiber optic sensing, fiber optic amplifiers, test and measurement, high-speed optical communications, EDFA, CATV, CWDM/DWDM, telecommunication networks, coherent communication systems, laboratory R&D, etc.
Conclusion
PM WDM and isolator hybrid combines filter WDM and isolator into a compact package to offer a low-cost-saving solution. It is ideal for fiber optic amplifier applications to combine signal and pump wavelengths with stable signal isolation. It provides high channel isolation, extinction ratio, reliability, and low insertion loss, PDL, and PMD.
