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, EDFA systems, external modulators, interferometric sensors, integrated optics, optical switching, and high-speed transmission devices where polarization stability is critical.
What wavelengths are supported by this PM fiber optic patch cord?
This PM patch cord is available for alignment wavelengths from visible to infrared, 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 version, the operating wavelength range covers approximately 350 nm to 2200 nm.
What connector types are available for the polarization maintaining patch cord?
The PM patch cord can be terminated with common fiber optic connectors including FC, SC, and LC according to the datasheet, with additional options such as ST, MU, MPO, MTP, and other connector types available upon request. FC connectors can be supplied with narrow key or wide key configurations.
What is the insertion loss and extinction ratio of this PM patch cable?
Insertion loss depends on wavelength and 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. The extinction ratio ranges from a minimum of 15 dB at shorter wavelengths to 23 dB at 1300 nm, 1550 nm, and 2000 nm, with 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. Fast-axis alignment or other axis-orientation requirements can be specified when ordering, which is important for matching the polarization axis of lasers, modulators, and other PM fiber components.
What is the difference between UPC and APC polishing for this PM patch cord?
UPC and APC polishing affect optical return loss. This PM patch cord offers 50 dB return loss with UPC polishing and 60 dB return loss with APC polishing. APC connectors are typically preferred when lower back reflection is required, such as in laser systems, coherent communication links, and precision sensing setups.
What cable and fiber options are available for this polarization maintaining fiber patch cord?
The patch cord can be supplied as 250 μm bare fiber, 900 μm buffered fiber, 2.0 mm cable, 3.0 mm cable, or armored cable. It uses PM panda fiber, with fiber options from manufacturers such as Nufern, Corning, Fujikura, YOFC, or a customer-specified equivalent.
