Single Mode Hybrid Fiber Optic Patch Cables




  • FC/PC to FC/APC or FC/PC to SMA Cables
  • 1,2, or 5 m Long Cables
  • Custom Cables Also Available

Features

  • Single Mode Fiber Optic Adapter Cables for Signal Transmission from 305 nm to 2100 nm

  • Narrow Key FC/PC and FC/APC Connectors
  • Custom Cables Offered

Thorlabs' hybrid fiber optic patch cables feature FC/PC and FC/APC connectors or FC/PC and SMA connectors. These cables simplify connections at interfaces in fiber applications. FC/PC and FC/APC connectors features a high-quality machine polish for return losses of 50 dB or greater, while SMA connectors are hand polished to ensure optimal ferrule height tolerance (0.3860" - 0.3863").

All cables include a Ø3 mm FT030-Y Protective Jacket and two protective caps that shield the ferrule ends from dust and other hazards. Additional CAPF Plastic Fiber Caps and CAPFM Metal Threaded Fiber Caps for FC/PC- and FC/APC-terminated ends or CAPM Rubber Fiber Caps and CAPMM Metal Threaded Fiber Caps for SMA-terminated ends are also sold separately. Mating sleeves are also available to connect FC to FC, SMA to SMA, and FC to SMA connectors. These mating sleeves minimize back reflections and ensure proper alignment of fiber cores.

For shorter wavelengths, Thorlabs also offers Low-Insertion-Low Patch Cables, which feature handpicked single mode fiber with tighter core concentricity specifications for lower insertion loss and higher transmission. We also offer AR-Coated Single Mode Patch Cables, which have an antireflective coating on one fiber end for higher performance in fiber-to-free space applications. If you cannot find the appropriate stock patch cable your application requires, Thorlabs also offers custom patch cables with same-day shipping.

  • Fiber is hand selected to ensure higher cutoff wavelength. For SM operation near the cutoff wavelength, launch conditions need to be taken into consideration.
  • Wavelength range is illustrative and not guaranteed.
  • MFD is nominal, calculated value, estimated at the operating wavelength(s).
  • Attenuation is specified for bare fiber.
  • Return Loss is defined for the unterminated connector. For example, if your source is connected to the FC/PC end, your return loss will be the FC/APC measurement of 60 dB.
  • Insertion Loss is not specified for SMA connectors because they use an air gap for fiber-to-fiber connections, which can result in higher back reflections.
  • All FC/PC and FC/APC connectors feature a 2.0 mm narrow key.

  • Wavelength range is illustrative and not guaranteed.
  • MFD is nominal, calculated value, estimated at the operating wavelength(s)
  • Attenuation is specified for bare fiber.
  • Attenuation of SM2000 fiber is highly dependent on wavelength.
  • Return Loss is defined for the unterminated connector. For example, if your source is connected to the FC/PC end, your return loss will be the FC/APC measurement of 60 dB.
  • Insertion Loss is not specified for SMA connectors because they use an air gap for fiber-to-fiber connections, which can result in higher back reflections.
