Frequently Asked Questions

What is a polarization maintaining patch cord used for?
A polarization maintaining patch cord is used to transmit linearly polarized light while preserving its polarization state. This TARLUZ PM fiber optic patch cord is designed for applications such as coherent optical communications, EDFAs, high-speed transmission devices, switching, integrated optics, external modulators, and interferometric fiber optic sensors.
Which wavelengths are supported by this PM fiber optic patch cord?
The patch cord is available for multiple alignment wavelengths, including 375 nm, 405 nm, 460 nm, 630 nm, 780 nm, 980 nm, 1064 nm, 1300 nm, 1550 nm, and 2000 nm. Depending on the selected fiber, the wavelength range can cover from 350 nm to 2200 nm.
What connector types are available for the polarization maintaining patch cord?
The datasheet lists FC, SC, and LC connector types, with PC/UPC or APC polishing options. The product description also indicates that ST, MU, MPO, MTP, and other connector types may be available upon request. For FC connectors, both narrow key and wide key options can be supplied.
What are the insertion loss and extinction ratio specifications?
Insertion loss depends on wavelength. Typical insertion loss ranges from about 0.3 dB at 1300 nm, 1550 nm, and 2000 nm to about 1.2 dB at shorter visible wavelengths. The maximum insertion loss ranges from 0.5 dB to 1.5 dB. Extinction ratio also depends on wavelength, with minimum values from 15 dB to 23 dB and typical values up to 25 dB.
Can the slow axis or fast axis be aligned to the connector key?
Yes. By default, the slow axis of the PM panda fiber is aligned to the connector key. The fast axis can also be aligned to the connector key upon request, making the patch cord suitable for systems that require a specific polarization axis orientation.
