This circulator is tailored for applications requiring high performance in both the C and L wavelength bands, making it a versatile solution for modern optical communication systems. Its polarization-insensitive design ensures consistent performance regardless of the polarization state of the incoming light, which is essential for maintaining signal integrity in complex network environments.

Utilizing proprietary micro-optics packaging and robust metal bonding techniques, this circulator delivers low insertion loss and high isolation, minimizing signal degradation and crosstalk. The device is engineered for high stability and reliability, ensuring long-term operation even in demanding conditions. Its compact form factor allows for easy integration into dense network infrastructures, while its low polarization dependent loss (PDL) further enhances signal quality.

The 3-port configuration is ideal for routing signals in dense wavelength division multiplexing (DWDM) systems, optical add/drop multiplexers, and bi-directional communication setups. It is commonly used in conjunction with fiber Bragg gratings, optical amplifiers such as EDFAs, and in test and measurement instruments like optical time domain reflectometers (OTDRs). The circulator not only protects sensitive components from back-reflected signals, similar to an isolator, but also enables the efficient utilization of rejected light for monitoring or feedback purposes.

Designed to meet the rigorous demands of contemporary fiber optic networks, the DK Photonics C+L Band 3-Port Polarization Insensitive Optical Circulator stands out for its cost-effectiveness, high reliability, and adaptability. It is an excellent choice for system integrators and network operators seeking to optimize signal routing, enhance network performance, and ensure robust protection for critical optical components in a wide range of applications.

Frequently Asked Questions

What is a C+L Band 3 port Polarization Insensitive Optical Circulator?
A C+L Band 3 port Polarization Insensitive Optical Circulator is a compact, high-performance fiber optic device that routes light signals from Port 1 to Port 2, and from Port 2 to Port 3, while preventing back-reflected signals from returning to the source. It operates across the C and L telecommunication bands and is designed to be insensitive to the polarization of light, ensuring stable performance in various optical systems.
What are the main applications of the DK Photonics 3 port optical circulator?
The DK Photonics 3 port optical circulator is widely used in WDM systems, optical fiber amplifiers, pump laser sources, fiber optic sensors, test and measurement setups, instrumentation, dispersion compensation, EDFA applications, and optical time domain reflectometer (OTDR) measurements.
What are the key features of the DK Photonics optical circulator?
Key features include low insertion loss, high isolation, low polarization dependent loss (PDL), high stability and reliability, and cost-effectiveness. Its compact design and proprietary metal bonding micro-optics packaging further enhance its performance and durability.
How does a 3 port optical circulator differ from an optical isolator?
While both devices protect the input fiber from back-reflected signals, a 3 port optical circulator not only blocks return signals but also routes them to a third port, allowing the rejected light to be utilized elsewhere in the system. An isolator simply blocks or absorbs the return signal without redirecting it.
Is the DK Photonics optical circulator compatible with custom configurations?
Yes, DK Photonics offers custom circulators tailored to specific requirements, including custom fiber pigtails, different operating wavelengths, and varying power handling capabilities. Customers are encouraged to provide their desired specifications for a tailored solution.
What should I consider when ordering a DK Photonics optical circulator with connectors?
When ordering with connectors, note that the insertion loss will be 0.3dB higher and the return loss will be 5dB lower compared to devices without connectors. It is also not recommended to choose a 250μm bare fiber pigtail if a connector is required.
How do I select the correct part number for my application?
To select the correct part number, use the ordering information format provided by DK Photonics (P/N: PIOC-①-②-③-④-⑤-⑥-⑦) and specify your required parameters. Providing a detailed description of your application and requirements will help ensure you receive the optimal product configuration.
