product description
The PMTI series polarization maintaining tap isolators are advanced optical components that provide excellent performance for optical communication systems. This isolator combines the functions of a tap coupler and a polarization sensitive isolator in a compact package, greatly changing the way signals are managed in fiber optic systems. Here are some key features of the PMTI series:
High extinction ratio (ER): The PMTI series provides a high extinction ratio of at least 20 dB, which means it can effectively attenuate unwanted polarized light, improving signal quality and reliability
Ultra low insertion loss: The insertion loss of the isolator is very low, ensuring the high efficiency of the signal during transmission, thereby improving the overall system efficiency.
High Return Loss: The PMTI series has a return loss of up to 50 dB, which helps reduce the optical signal reflected back to the light source, lower noise, and improve system performance
Polarization insensitive design: This design ensures consistent performance across various polarization states, making it suitable for different application scenarios.
High power processing capability: The PMTI series can handle up to 500 mW of continuous optical power, suitable for high-power fiber lasers and amplifiers.
Wide working temperature range: The isolator can operate stably within a working temperature range of 0~+70 ℃, ensuring stable performance under different environmental conditions.
Customizable options: GKER offers high and low reflectivity gratings with various bandwidths and precise matching to meet different application needs.
Heat dissipation packaging or only recoating: Isolators can be equipped with heat dissipation packaging or only recoating to meet different application requirements and improve thermal management efficiency.
These characteristics make the PMTI series polarization maintaining tap isolators an ideal choice for a wide range of applications in telecommunications, fiber optic networks, research, and other fields, especially in those that require high polarization extinction ratio and signal integrity. By precisely controlling the polarization state of light, the PMTI series isolators help improve the overall performance and reliability of the system.
