Pigtailed LEDs, Multimode Fiber
![](https://www.thorlabs.com/Images/GuideImages/12631_Pigtailed_LEDs_1.jpg)
- LEDs in the Visible or Near-IR Spectral Ranges
- Pigtailed, Ø9 mm TO-Can Package
- Ø400 µm or Ø1000 µm Core Multimode Fiber with SMA905 Connector
- Custom LED Pigtails Available
A fiber-pigtailed LED mounted to a PTLB1 bracket. The LED connector pins, clipped to 0.15" (3.8 mm), are inserted into an SR9F ESD protection / strain relief cable. The SR9F can then connect to a controller to drive the LED.

- Custom LED Pigtails Available by Contacting Tech Support
Thorlabs' light-emitting diodes (LEDs) are pigtailed with multimode (MM) fiber and are available at visible or NIR spectral ranges with center wavelengths from 470 nm to 810 nm. Based on Ø9 mm TO-packaged diodes, these LEDs feature either Ø400 µm core MM fiber (Item # suffix S04) or Ø1000 µm core MM fiber (Item # suffix S10). The fiber ends are terminated with an SMA905 connector.
Each LED is coupled to the multimode fiber using a butt-coupling technique. During this process, the fiber connector is positioned so that the end of the fiber will be as close as possible to the emitter, thereby minimizing losses at the fiber input and maximizing output power. Each LED undergoes a high-quality MM pigtail alignment process during manufacturing to ensure that the coupling efficiency is maximized.
Complete specifications, as well as spectrum and L-I-V plots, are provided by clicking on the blue info icons () in the tables. This information is also provided in the spec sheets, which can be accessed by clicking on the red docs icon (
) next to the Item # below. Each unit is tested before shipment and includes a product-specific datasheet; click here for a sample.
LEDs are sensitive to electrostatic discharge (ESD). Please take the proper precautions when handling the device; see ESD protection accessories.
Mount and Driver Options
These LEDs are compatible with mounts and drivers that accept pigtail packages with Pin E or Pin H configurations. Compatible laser diode mounts can be found here, and we offer a wide variety of compatible laser diode current drivers. For the EP590Sxx, EP700Sxx, and EP810Sxx LEDs, we recommend the CLD1010LP, which is an all-in-one, combined mount and driver that serves as both a current and temperature controller. Our pigtailed LEDs can also be connected to the CAB-LEDD1 connection cable that is included with our LEDD1B LED current driver (sold separately); this option requires the bare wires on the CAB-LEDD1 cable to be soldered to the pins on the LED.
Fiber Care
We recommend cleaning the fiber connector of the pigtail package before each use if there is any chance that dust or other contaminants may have deposited on the surface. To view our fiber cleaning products, click here. The intensity at the center of the fiber tip can be very high and may burn the tip of the fiber if contaminants are present. While the connectors on these pigtailed LEDs are cleaned and capped before shipping, we cannot guarantee that they will remain free of contamination after they are removed from the package. We also recommend that the LED is turned off when cleaning the fiber or when connecting or disconnecting the device from other fibers.

 (posted 2019-12-15 17:12:40.253) Is the output of the diode polarized? If the diode is damaged, how can it be removed from the pigtail? YLohia
 (posted 2019-12-16 11:22:14.0) Thank you for contacting Thorlabs. The output from the fiber pigtail is not polarized. The LED chip cannot be removed from the pigtail. If the chip is damaged, unfortunately, the unit cannot be repaired. However, fiber/connector damage can be repaired in certain cases. user
 (posted 2019-04-17 07:41:50.587) The title reads 1000 mA, but the specs inside the product box reads 500 mA with 750 mA maximum. So I bought a 1000 mA driver which now is of no use because I need a 500 mA driver. Please make sure you specify the correct values for the LED. YLohia
 (posted 2019-04-29 11:03:29.0) Hello, thank you for contacting Thorlabs and my apologies for any issues caused by this. I had reached out to you directly at the time of this posting to gather more details. May I ask what driver you purchased? Most drivers should be able to supply variable current, which means that you should still be able to use the 1000mA driver. Also, would you be able to send us a picture of the part where a different max current (750mA) is specified on the spec sheet? Robson Sampaio
 (posted 2019-04-05 07:31:21.763) Would it be possible to unmount the device and switch the LED? YLohia
 (posted 2019-04-05 09:19:31.0) Hello, thank you for contacting Thorlabs. Unfortunately, this would not be possible as the package is sealed and the fiber is carefully aligned to maximize the coupling efficiency. However, we may be able to offer a custom solution if you require a different wavelength. Please email us at techsupport@thorlabs.com if you are interested in a custom solution with details about wavelength, fiber core size, minimum output power, and quantity. |
