Furcation Tubing
Furcation tubing, also commonly referred to as jacketing, is used to protect delicate optical fiber from damage. The color of tubing is typically chosen to represent the type of fiber patch cable. Yellow tubing is the industry standard for single mode fiber, orange designates multimode fiber, and blue is typically reserved for polarization-maintaining fiber. Black tubing prevents visible light from entering through the length of the fiber. For additional light blocking, FT030-BK black tubing can be placed inside FT05SS or FT061PS stainless steel tubing.

When selecting furcation tubing, please note its inner diameter, as this dimension must be larger than the outer diameter of the fiber you are using. As an alternative to jacketing your own fiber, Thorlabs offers custom pre-made patch cables. Please contact Tech Support for further information about Thorlabs' jacketing capabilities.

Stainless Steel Furcation Tubing and Sleeves
Thorlabs offers several stainless steel options for furcation tubing that provide high rigidity, but with a larger bend radius. Generally, the smallest tubing that the fiber fits in will be ideal, but it is sometimes benefical to use a larger tubing to protect fibers with larger bend radii. Our stainless steel sleeves effectively replace the strain relief boot used with our standard furcation tubing and shield the connection from dust, dirt, and other external contaminants.

Fiber Connector Caps
Dirt on the fiber tip can result in permanent damage to the fiber connector. This can result in increased coupling losses or undesirable mode structure in the output light. To prevent damaging the connectorized fiber, clean the tip before each use and use a fiber connector cap to protect the end face of the connectorized fiber when it is not in use (see our fiber optic cleaning products). Thorlabs offers caps for Ø1.25 mm, Ø2.5 mm, and Ø3.2 mm fiber connector ferrules; metal caps for FC and SMA connectors; and caps for FC, SMA, or ST bulkheads and mating sleeves. See below for more information.

Hi, Can you please confirm the tooling needed to connect this part to the FT061PS tubing? Thanks.
Poster:nbayconich
Posted Date:2017-06-05 02:32:32.0
Thank you for contacting Thorlabs. The FT061PS tubing can be directly attached to the FTS61A mating sleeve using the F123 epoxy. Feed the connector/sleeve over the fiber, add a small amount of epoxy to the large inner diameter of the sleeve, then the furcation tubing. No crimping tools are needed to connect the FTS61A to the FT061PS tubing. A Techsupport representative will contact you directly.

Dear I would like to know what is the attenuation of FT030 optical fiber to 710nm. best Andres Aragoneses

Response from Bweh at Thorlabs USA: The FT030 is a furcation tubing or jacket used to protect delicate optical fiber. The It doesn't introduce any attenuation to the optical mode that propagates in the core of the fiber. It seems you would like to know the attenuation of a particular fiber at 710nm. I will follow-up with you to know which fiber you are referring to.

The product FT030 from our last order is much different from our previous one. The inner tube is softer and it's much harder to feed the fiber in it. The color of the inner tube is not as white (not the same material?). Overall regidity is also lower. We are only able to feed a few meters of fiber in it. Cannot order anymore since we are not sure of what we will get. Also, it would be useful to have a 25 pack of relief Boots and Crimp Sleeves for 3mm tubing like product 190066CP that already exist for 2mm tubing.

Response from Phong at Thorlabs: We are aware of the recent change to the characteristics of the inner tubing and are sorry to hear that you're experiencing some difficulty with it. Though this change has not impacted our usual production of patch cables, we will contact you directly to address your concerns regarding the inner tubing's rigidity.

It would be nice, if you would also be offering splice sleeves. Another product, which would be nice would be a plastic or metal box, with FC bulkhead connectors at one side. Similar to your interferometer housings but without the detectors and the interferometer inside.

A response from Ken at Thorlabs to qiangqiang.tai: FT030 is just the item number for the tubing and 973-579-7227 is actually our phone number in USA. There should be a white label on the cable with the item number of the cable itself on it. Please find out what that number is so we can determine which fiber you have.

Dear Ms. or Mr. This is Philips Research Eindhoven. I am writing this letter for more information about your product FT030. The sery number of the fiber we are using is 973-579-7227 FT030. 1, Is this a single mode fiber which can maintain the states of polarization? 2, How many states of polarization would there be under the laser source of wavelength 780nm, linear polarized light? 3, What will be the alternative fiber for the purpose of getting linear polarized light regarding to the laser source we are using? 4, What would be the delievery time? Best regards, Qiangqiang Tai

Ø900 µm Furcation Tubing

Item # Inner Diameter Outer Diameter Color Material Operating Temperature
FT900Y 400 µm 900 µm Yellow Hytrel™ (UL 94 HB) -40 to 70 °C

Thorlabs' FT900Y Furcation Tubing is Hytrel™ tubing with a 900 µm outer diameter. With an inner diameter of 400 µm, it is most commonly used with single mode fiber and may be too small for many multimode fibers. It does not have an inner tube, Kevlar threads, or a pull string for feeding fibers through it. FT900Y tubing can be removed after installation by using the AFS900 Adjustable Fiber Buffer and Jacket Stripping Tool. Thorlabs also offers the 190044P Yellow Strain Relief Boot for covering connector ends when using Ø900 µm furcation tubing.

The FT900Y furcation tubing has several differences from our former FT900SM tubing. The FT900Y has an inner diameter of 400 µm and does not include Kevlar threads, which can be used as a pull string. For more information on differences, please contact us at techsupport@thorlabs.com.

Item # Inner Diameter Outer Diameter Color Operating Temperature
FT020 900 µm 2.0 mm Orange -40 to 70 °C
  • Fits up to 900 µm Outer Diameter Fiber
  • Lightweight Alternative to Ø3.0 mm or Ø3.8 mm Tubing
  • Kevlar Protective Threads

Our Ø2.0 mm protective tubing provides more protection than Ø900 µm tubing and fits optical fiber up to 900 µm in diameter. It has an internal structure similar to our Ø3.0 mm tubing pictured below, including a PVC outer jacket, Kevlar threads, a polypropylene inner protective tube, and a pull string for fiber insertion. It is ideal for constructing patch cables for optogenetics or any other application where a lightweight, flexible, and durable patch cable is needed. The AFS900 Adjustable Stripping Tool can be used to remove this tubing after installation.

We also offer connector boots and crimp sleeves to use Ø2.0 mm tubing with FC connectors (Item # 190066CP) or ST or SMA connectors (Item # 190088CP). Our stock connectors do not include a boot compatible with Ø2.0 mm tubing. Please note that, due to the small size of this tubing, epoxy must be used after crimping a sleeve from the 190066CP or 190088CP packs to the tubing to ensure that it is properly secured to the tubing. For information on using this tubing with other connector styles, please contact Technical Support.

Sleeve Schematic

Thorlabs' FT23SS Stainless Steel Tubing and FTS23x Sleeves provide a high degree of fiber protection. This thin, lightweight stainless steel tubing provides added protection for more rigorous optogenetics experiments. Its all-metal jacket also prevents visible and IR light from entering through the length of the patch cable. The FTS23x sleeves effectively replace the strain relief boot used with our standard furcation tubing and shield the connection from dust, dirt, and other external contaminants. Please refer to the Compatibility Guide table below to ensure the proper match between the fiber connector and sleeve.

To create a fiber connection, our F112 or F123 Epoxy is used to secure the sleeve along the same central axis as the fiber connector, tubing, and bare fiber. Each sleeve is engraved with a part number ending in an A, B, or D that indicates the inner diameter of the connector side of the sleeve, as shown in the table below. When the fiber connector and tubing are fed into the sleeve, they each encounter a hard stop once they are completely inserted, making it easy to create reliable connections.

The bare fiber can be fed directly into the tubing, which does not contain an inner tube, Kevlar threads, or a pull string. 

Please note that the maximum continuous length we can provide for this tubing is 200 m.

Operating Temperature: -20 to 70 °C (-4 to 158 °F)

Thorlabs' FT030 and FT038 Furcation Tubings consist of an outer PVC jacket, Kevlar protective threads, a polypropylene inner fiber tube, and a pull string for fiber insertion, as shown in the photo to the right. The Kevlar threads that surround the inner tube protect the fiber from damage by cushioning any impact incurred by the PVC outer jacket. 

These furcation tubings can be used with SM (yellow standard), PM (blue standard), and MM (orange standard) fibers. Our FT030-BK and FT038-BK Black Furcation Tubing are especially useful for preventing visible room light from entering the patch cable. For additional light blocking, the FT030-BK tubing can be placed inside FT05SS or FT061PS stainless steel tubing. The tubing can be removed from the fiber by using the FTS3 Stripping Tool and the T186 Kevlar Cutting Shears. Feeding fiber through furcation tubing can be difficult, so the inner tubes of the FT030 and FT038 feature a pull string to help guide the fiber.
