Thorlabs' Polarization-Maintaining Pigtailed Ferrules with Connectors are designed to be paired with our GRIN lenses to simplify coupling of visible, near infrared, or infrared light between a fiber and a free-space optical system. The borosilicate glass ferrule is pigtailed with polarization-maintaining (PM) PANDA fiber to maintain the polarization of the incident light. For applications that require single mode (SM) fiber, however, Thorlabs also offers SM pigtailed ferrules with connectors and SM pigtailed ferrules without connectors

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 VAR or broadband AR coating. The PMPX1 and PMPX4 have a VAR coating of 630 ± 30 nm. The PMPX2 and PMPX5 feature a broadband AR coating of 700 - 900 nm, while the PMPX3 and PMPX6 feature a broadband AR coating of 1260 - 1650 nm. The coating lowers the average reflectivity 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 feature an 8° face angle to maximize the return loss by back reflecting the incident light at a non-normal angle. This face angle is preferred over a normal face when collimating the output light. 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.

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.
