Polarization Maintaining (PM) Fiber Optic Circulator (780nm)

Name: Polarization Maintaining (PM) Fiber Optic Circulator (780nm)
Brand: Ascentta
Availability: InStock

Description

The PMVCIR 780nm Polarization-Maintaining Optical Circulator by Ascentta, Inc. is a compact and high-performance three-port fiber optic circulator designed for polarization-maintaining applications.

It transmits signals from port 1 to port 2 and from port 2 to port 3 simultaneously, making it ideal for use in sensing and communication systems with fiber gratings and other reflective components. Ascentta, Inc. also offers multiport circulator modules with up to N<=8 ports.

Ascentta also offers single mode polarization independent circulator in 780nm and other wavelength range such as 405nm, 532nm, 650nm, 785nm, 850nm, 980nm, 1030nm, 1064nm and telecommunication wavelengths.

Frequently Asked Questions

What is the function of the 3-Port Optical Circulator?

The 3-Port Optical Circulator is a device that directs light from one port to another in a specific sequence, typically from port 1 to port 2 and then from port 2 to port 3, while isolating the reverse direction.

What is the maximum optical power handling capacity?

The maximum optical power handling capacity varies by wavelength; for 780nm, it is 150mW.

What are the operating and storage temperature ranges for the circulator?

The operating temperature range is 10°C to 50°C, and the storage temperature range is 0°C to 60°C.

How does adding connectors affect the circulator's specifications?

Adding connectors can affect the insertion loss (IL), return loss (RL), and extinction ratio (ER) of the circulator.

What is the extinction ratio for the circulator?

The minimum extinction ratio is 20 dB for wavelengths 780nm and above.

What are the package dimensions for the circulator?

The package dimensions are Φ24xL65 mm. Other wavelengths may have different dimensions.
