The supported operating wavelength ranges span from 350–460 nm for UV/visible applications up to 1850–2200 nm for 2 µm systems.
What connector types and polishing options are supported?
The PM patch cord can be terminated with common fiber optic connectors including FC, SC, and LC, with other connector types such as ST, MU, MPO, and MTP available by request. Polishing options include UPC/PC and APC. For FC connectors, both narrow key and wide key options are available, supporting precise polarization axis alignment.
What insertion loss and extinction ratio does this polarization maintaining patch cord provide?
The insertion loss depends on the operating 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 extinction ratio is also wavelength dependent, with typical values from 17 dB at 375/405 nm up to 25 dB at 1300 nm, 1550 nm, and 2000 nm.
Can the slow axis or fast axis be aligned to the connector key?
Yes. By default, the slow axis of the PM fiber is aligned to the connector key. The fast axis can also be aligned to the connector key upon request. This is important when integrating the patch cord into polarization-sensitive optical systems such as modulators, interferometers, coherent receivers, and PM fiber amplifiers.
