Panda Style Fiber

Features

Narrow Key (2.0 mm) Aligned to Slow Axis
Typical Return Loss of 50 dB (40 dB Min)
Ceramic Radiused Ferrules (UPC)
Ø3 mm Protective Outer Jacket
Custom Patch Cables Available (See Tab Above)

These polarization-maintaining fiber optic patch cables are connectorized on both ends with high-quality, narrow key, ceramic FC connectors. Manufactured in our facility, each cable is individually tested to ensure its extinction ratio and low back-reflection (return loss) at fiber-to-fiber junctions. These cables are available from stock and feature a high-quality polish, which leads to a typical return loss of over 50 dB.

Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards. Additional CAPF Fiber Caps for FC/PC-terminated ends are also sold separately.

Response from Tim at Thorlabs: Thank you for your feedback. The attenuation for these cables can be found by clicking on the fiber type located directly above the patch cables. By clicking on the "Documents" tab you can access the specification sheet, which has the attenuation in dB/km.

What is the maximum attenuation for these path cables in dB/km. Is it the same as for the regular single mode patch cables?

A Response from Sean at Thorlabs: Thank you for your feedback. I have added the nominal numerical aperture to all of our PM fiber patch cable pages. These values may be found by clicking on the Specs tab of each page. Complete fiber specifications may also be found by clicking on the fiber part number listed in the Specs table.

What is the NA of these fibers? I plan to connect this to a fixed fiber collimation package (F280APC-A, NA = 0.15). To have higher than 50% coupling efficiency into that, I am expecting this PM fiber to have NA ~0.15 which is similar to the non-PM SMF.

A response from Ken at Thorlabs: 3W is too much for these cables. The epoxy used to glue the connector will not withstand that and it will burn the fiber and connector. We usually recommend 300mW as the maximum power.

Is it possible to use the P1-488PM-FC-5 with a 3 watts argon laser at 488nm (continues)? Or could there be issues with the power?

Response from Laurie at Thorlabs to j.d.ellis: Thorlabs does offer PM patch cables for 633 nm. Any of the following PM fibers, which all operate at that wavelength, can be ordered as patch cables: PM630-HP, HB600, or PM-S630-HP. We would just need to know what length, jacket, and connector you require. In addition, we offer 24-hour turnaround on stocked items. Please call our tech support staff for pricing and to specify your requirements (973-579-7227).

Do you have any patch cables for PM fibers for 633nm wavelength? I find it ridiculous that you have the couplers for 633 but not the fiber...
