2x2 Single Mode Fused Fiber Optic Couplers

Features

  • Operating Wavelengths from 488 - 1550 nm
  • OCT-Proven Broadband Couplers Centered at 850 nm or 1310 nm
  • Optically Reversible
  • 99:1 Coupling Ratio for use as a Signal Tap
  • Polarization Insensitive
  • Ø900 µm Loose Jacket
  • Contact Us for Custom Wavelength and Connector Options, Typically Ship Same Day

Thorlabs offers single mode 2x2 fiber couplers with center wavelengths from 488 - 1550 nm. These couplers are available with a 50:50, 90:10, or 99:1 split ratio. Additionally, these couplers are bidirectional, allowing any one of the ports to be used as an input port. The FC850 and FC1310 series are broadband couplers that have been designed and tested for Optical Coherence Tomography (OCT) systems. Our couplers are offered with FC/PC connectors, FC/APC connectors, or unterminated.  If a custom connector configuration is needed please contact your local Thorlabs office. For small orders, same-day turn around is possible if the order is placed before 12 PM EST. All fibers have a 900 µm diameter loose jacket.

Refer to the Coupling Example tab above for application details.

General Operation

In the diagram below, a 90:10 2x2 coupler is shown schematically. Since the coupler is bidirectional, either end of the coupler may be used as the input (i.e., either end A or end B). Any one of the four fibers may be used as a single input. On the other end of the coupler, one fiber will have 10% of the input signal, while the other fiber will have 90% of the signal. While the fibers are color-coded, these are for user identification within a setup and do not indicate particular input or output ports.

Explanation of Selected Specifications

This tab provides a brief explanation of how we determine several key specifications for our 2x2 couplers. The legs of the coupler are defined as shown in the diagram below.

2x2 CouplerPicture

Figure does not represent a specific coupling ratio (for demonstrational purposes only)

Excess Loss
Excess loss in dB is determined by the ratio of the total output power to the total input power:

Excess Loss

Pport1 is the input power at port 1 and Pport3+Pport4 is the total output power from Ports 3 and 4, assuming no input power at Port 2. All powers are expressed in mW.

Directivity
The directivity refers to the fraction of input light that exits the coupler through an input port instead of the intended output port. It can be calculated in units of dB using the following equation:

Directivity or Return Loss

The fraction in the logarithm is the ratio of the input power at port 1 to any output power detected at port 2. This output is the result of some back reflection at the junction of the legs of the coupler and represents a loss in the total light output at ports 3 and 4. All powers are expressed in mW. For a 50:50 coupler, the directivity is equal to the return loss.

Insertion Loss
The insertion loss is determined by the ratio of the input power to the output power from one leg of the coupler. It can be generally written as

Insertion Loss

where the powers are in mW and the resulting insertion loss is in dB. To use a more specific example, the insertion loss of a signal from Port 1 to Port 3 may be written as

Insertion Loss

and the insertion loss from Port 1 to Port 4 as

Insertion Loss

Similar equations can be formulated using Port 2 as the input arm.

Insertion loss can also be easily calculated with the power expressed in units of dBm. The power in mW is related to the power in dBm using the equation:

Conversion

Then, the insertion loss in dB can be calculated as follows:

Insertion Loss

Response from Bweh at Thorlabs - USA: Thanks for contacting Thorlabs. The 1064nm couplers will not work at 1175nm as this is limited to +/- 15nm spectral range. We can provide this to you as a special for now. We are working on expanding our coupler offerings. I will follow up by email for the special quotation and also inquire about your application to determine if we should add this wavelength as a stock item.

Response from Chris at Thorlabs: Thank you for your inquiry. This coupler is made using the HI1060FLEX fiber. We have a value for the core refractive index of 1.472. This was measured at 651nm, and should not vary greatly in the operating range. I'm afraid this is the only value available at the moment.

The SM optical couplers described on the website are similar to what we use currently here at nLIGHT, however I could not find any describing use of 80u cladding fiber. Is it possible to have a 90 - 10 80u cladding fiber tap/couplers made if it's not off the shelf? Thank you, Paul Smith Engineering Technician nLIGHT Photonics 360-980-1655

Response from Tim at Thorlabs: The FC532-99B-FC uses 460HP fiber. We will see attenuation from this fiber but out of band use will also significantly change the coupling ratio for single mode couplers. As you will have two separate wavelengths both will contribute different coupling ratios to each of the output legs. I will contact you to discuss this further with your specific wavelengths.

Response from Buki at Thorlabs: We will contact you to discuss your application further. However, it sounds like you may want a WDM (Wavelength Division Multiplexer): http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=375 A WDM can be used to combine or separate multiple single mode wavelengths. The closest to your request is WD202A, which is designed for 980nm and 1550nm. We will contact you directly to continue this discussion.

Response from Laurie at Thorlabs to venugopal486: Thank you for your interest in our products. These couplers are designed for use in the 850 +/- 40 nm range. Your broadband Ti:Sapphire Oscillator likely provides output in this range but also has output at other wavelengths outside of this range. For wavelengths outside of the couplers bandwidth, the 50-50 coupling ratio with be altered and attenuation is likely to occur. These couplers have not been designed for use with femtosecond sources, and thus, we do not currently have information on their performance for such sources. We rate this item for use with powers up to 300 mW, although we do have customer feedback indicating that they have been used suggessfully with output powers up to 500 mW. I hope that this additional information helps you decide whether this coupler is appropriate for your application. Please feel free to contact us if youd like to discuss any of these points in more detail.

850 nm OCT Broadband Fiber Optic Couplers
  • Center Wavelength: 850 nm
  • Wavelength Range ±40 nm
  • 1 m Long Fiber Leads
  • Operating Temperature: -40 to 85 °C

The FC850-40-50-APC OCT-proven broadband coupler is a polarization independent, passive, 2 x 2 single mode fiber optic component designed for use in the 810-890 nm range. An important consideration in the design of an OCT system is the flat spectral response of the components in the system. For more information, please see our full presentation on OCT couplers.
