Frequently Asked Questions

What is a polarization maintaining patch cord used for?
A polarization maintaining patch cord, or PM fiber patch cable, is used to transmit light while preserving its polarization state. It is commonly used in coherent optical communications, EDFAs, external modulators, interferometric sensors, integrated optics, switching systems, and high-speed transmission devices.
What wavelengths are available for this PM panda fiber patch cord?
This PM patch cord is available for alignment wavelengths including 375 nm, 405 nm, 460 nm, 630 nm, 780 nm, 980 nm, 1064 nm, 1300 nm, 1550 nm, and 2000 nm. The supported wavelength range depends on the selected fiber, covering options from 350 nm up to 2200 nm.
What connector types can be used with this polarization maintaining fiber patch cable?
Standard connector options include FC, SC, and LC. The patch cord can also be configured with other connector types such as ST, MU, MPO, or MTP upon request. FC connectors are available with narrow key, approximately 1.97 to 2.02 mm, or wide key, approximately 2.09 to 2.14 mm.
What insertion loss and extinction ratio does the PM patch cord provide?
Insertion loss depends on wavelength and connector configuration. 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. Typical extinction ratio ranges from 17 dB to 25 dB, with higher ER performance at telecom and near-infrared wavelengths.
