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/APC 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. Available from stock, these cables feature a high-quality polish, which leads to a typical return loss of over 60 dB.

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

I would like to ask that whether two fiber connected with a FC/APC connector can aligned to the slow axis? Was the inserted pin fixed the angle of the fiber end face as well as the slow axis? Thanks!

Response from Jeremy at Thorlabs: The connector key is aligned to the slow axis for our stocked PM patch cables.

What is the damage threshold for the P3-488PM-FC-2?

Poster: tcohen

Posted Date: 2012-08-15 10:15:00.0

Response from Tim at Thorlabs: The P3-488PM-FC-2 uses PM460-HP fiber. The MFD of this fiber is approximately 3.3 +/- 0.5 microns at 515 nm. When we look at the damage threshold of a fiber there are many considerations to take into account. The first is connectorization. The connectors here will already limit the damage threshold to a couple of Watts. Furthermore, we look at a general limit of silica at approximately 10mW/um^2. We see that 80% of the MFD is ~2.64um. Therefore, we would expect a working radius of ~1.32um. This would equate to ~54.7mW. Of course this is a theoretical approximation. Actual lab conditions will depend on where the incident light is focused (ie: high coupling efficiency?), how clean the fiber tip is, what the wavelength is, etc. I will contact you so that we can continue this conversation.

Response from Tim at Thorlabs: Thank you for your feedback! We do offer our Air-Spaced Doublet Collimators in a 2um APC compatible version: the F810APC-2000. We are also looking to expand our optics and our Fixed Fiber Optic Collimation Packages to include a 2um APC version in the near future.

Do you supply the suitable fiber collimator for 2000 nm PM FC/APC Patch Cable?

Response from Buki at Thorlabs: Thank you for your feedback. Yes, ER will decrease with long lengths of fiber but 2-5m is negligible. In general the longer wavelengths will see less change in PER for the same length of fiber. The physical environment will have more of an impact on PER than the length. Please contact TechSupport@thorlabs.com if you have further questions about this.

How come the extinction ratio is 20dB for both 2m and 5m? Shouldn't the E.R. get lower with fiber length?

Hi, can someone let me know what the damage threshold of the fibre/cladding is for the P3-780PM-FC-5? As in, if I put 1W into a 70% efficient fibre couple, Ill have 300mW leaking into the cladding. Will this damage the fibre or FC/APC connector?

I checked a few sources and found that blue is the defacto standard, so while it is not a fully ratified international standard it does seem reasonable for Thorlabs to join in making it one. I will ask for this change to be implement as quickly as possible... Alex Cable

A response from Greg at Thorlabs to brian.wojo: Thank you for your feedback regarding our PM cables. There isnt a standard for PM cables, but it is not uncommon to see blue tubing used. We are actually working on providing blue furcation tubing to our lineup for PM cables. This should be available shortly.

Im not sure if things have changed, byt for the past 15 years the industry standard for jacketing color coding is Orange for MM fiber, Yellow for standard SM fiber, and blue for PM fiber. Why do you not offer blue jacketing? This is very confusing to determine the fiber type without having a spec sheet in front of you. This potentially can cause our end-users endless confusion.
