  • AR Coated Glass Ferrules
    • 630 ± 30 nm, 980 ± 15, or 1064 ± 15 nm VAR Coatings
    • 700 - 900 nm or 1260 - 1650 nm Broadband AR Coating
  • 2.0 mm Narrow Key FC/PC or FC/APC Versions Available
  • Designed for Easy Pairing with GRIN Lenses
  • Pigtailed Glass Ferrule with 8° Face Angle

Pairing our selection of GRIN lenses with these pigtailed ferrules to collimate the output light satisfies many experimental needs, including coupling a diode laser into a fiber, focusing laser light onto a detector, or collimating laser light. Pigtailed glass ferrules are commonly used in optical isolators, switches, and circulators. The Ø1.8 mm ferrule is significantly easier to handle than an unterminated fiber end. The 1 m long, polarization-maintaining fiber embedded in the ferrule is protected by Ø900 µm blue Hytrel®* furcation tubing and terminated with a narrow key FC/PC or FC/APC connector. The FC/PC connectors feature a blue boot while the FC/APC connectors feature a green boot. 

These ferrules feature either a narrowband antireflective, or V, coating (VAR) or a broadband antireflective (AR) coating. The PMPX1 and PMPX4 have a VAR coating for 630 ± 30 nm; the PMPFX7 and PMPFX9 have a VAR coating for 980 ± 15 nm; and the PMPFX8 and PMPFX10 have a VAR coating for 1064 ± 15 nm. The PMPX2 and PMPX5 feature a broadband AR coating for 700 - 900 nm, while the PMPX3 and PMPX6 feature a broadband AR coating for 1260 - 1650 nm. The coating lowers the average reflectance in the specified wavelength range to below 0.25%, reducing back reflections and insertion losses in the design wavelength range. In addition, each of the glass ferrules features an 8° face angle to maximize the return loss by back reflecting the incident light at a non-normal angle. Our line of GRIN lenses provides an 8° face angle that is designed to match the pigtailed glass ferrules. Please see the Collimator Assembly tab above for all GRIN lenses that are compatible with our pigtailed ferrules.

Thorlabs also offers a complete selection of mating sleeves that ensure proper alignment of the cores of a terminated fiber end. For pre-assembled GRIN lens and fiber combinations, please see our SM pigtailed aspheric lenses or our SM, PM, and MM jacketed GRIN collimators. If you do not see a pigtailed patch cable that meets your application requirements, please contact Tech Support and we will design a specialty cable to meet your needs.

Using GRIN Lenses to Collimate Pigtailed Ferrules

All pigtailed ferrules can be collimated using our selection of GRIN Lenses along with a 51-2800-1800 mating sleeve, available below. This collimator can be assembled by inserting the lens and ferrule into opposing sides of the mating sleeve as shown in the images to the right. Gently bring them into contact to ensure that the faces are parallel, then bring the lens and ferrule apart until the desired focusing is achieved. For ease of assembly, we recommend using our spring-loaded micro V-clamp or tweezers to handle these small cylindrical components.

The SMPF01 and PMPFX series of pigtailed glass ferrules have an 8° face angle which is compatible with the 8° face angle of the GRIN23 series of lenses. The SMPF02 series of ferrules have a 0° face angle which is compatible with the 0° face angle of the GRIN29 lens series.

Use the table below to select between our PM and SM pigtailed ferrules and the corresponding compatible GRIN lenses. Our PM glass ferrules are offered with FC/PC or FC/APC connectors while our SM ferrules are offered with both of these connector types or without a connector.

Dear Sir We are intresting in your 1550 nm ferrule and we have some questions : 1. What is the accuracy of the 8° polish angle?. I would like 8.0° ± 0.1° 2. What is the accuracy of the fiber core assembly related the mechanical axis of the ferrule? 3. Please send us the tolerance of the output beam angles (Pitch and Yaw) related the mechnical axis of the ferrule Thnak you very much for your nice help Sincererly yours Aner Lev
cdolbashian  (posted 2022-10-14 03:53:05.0)
Thank you for reaching out to us with this inquiry. To answer each of your questions in order: The accuracy of the polish angle is 8°±1°, the concentricity of the ferrule is ≤15um, and finally, the pitch would be~3.59° with a a yaw of ~0°.

“I have a question on your SM600 and / or PM660-HP fiber optic cable. I want to launch into it a 633 nm wavelength to deliver a SM beam at its output , which is within its nominal specifications, Since this SM600 fiber core is 3.5-5.2 um, all be ok. (normally a 4,2um is the proper core diameter for such wavelength, tough ) Now comes the question. By chance I expect to launch into it a 405nm wavelength beam , for which it would require a 3um core, but knowing that my porpouse FOR this 402nm wavelenght IS NOT to deliver a SM TEM00 mode, but a MM output at this 405nm is OK with my application, while needing a 632nm SM output. Is it proper to use this SM600 fiber optic cable for such porpouse ? (I accept that there may be addtional attenuation at 405nm , no problem with me, I will commpensate input power at 405nm (I am assuming a 2 -50 mW range max for both wavelenghts. My expected products are: PMPFX1 Customer Inspired! PM Pigtailed Ferrule, Ø1.8 mm, 8°, 630 nm, FC/PC combined with: PM630-HP + GRIN2306A Many thanks for your help Luis” Colchero lcolchero@cofis.es
YLohia  (posted 2021-03-25 10:54:28.0)
Hello, since the cut-off wavelength of the PM630-HP is specified to be 570 ± 50 nm, the 405 nm light will propagate as multimode while the 632 nm light will be single mode. Since you don't mind the multimode behavior and a higher loss at 405 nm, I would expect this to be fine for your application.
Laurance Lingvay  (posted 2020-03-06 12:00:13.65)
Could you please tell me the orientation of the PM fiber polarization state relative to the 8 deg angled surface. Thank you, Larry

Hello Larry, thank you for contacting Thorlabs. The 8° fiber end face is angled on a plane parallel to the fast axis.
