Multicore Fiber Fanout

Multicore Fiber FanoutMulticore fiber is increasingly of interest for applications ranging from sensing to spatial division multiplexing to high density coupling. Addressing individual cores of these fibers is what Chiral’s Multicore Fiber (MCF) Fanout enables.

Fanouts are typically shipped in spliced pairs, as shown here for a 7-core MCF. This configuration enables full testing of insertion loss and crosstalk for each pair. MCF and pigtail lengths can be tailored to your needs. Fanout pigtails, two pairs of 7 fibers shown on left in this example, are typically standard singlemode fibers.

Multicore fiber is often supplied by the customer and the fanout is matched to the fiber. However, Chiral also stocks some multicore fiber and can supply both the fanouts and MCF, as preferred. Fanouts can also include connectorization and assembly with other components, as desired. Chiral Photonics, to date, has supplied fanouts for MCF with 2 to12 channels in a variety of configurations. Some exemplary MCF fibers that we have fabricated fanouts for are shown below, along with related citations. Please speak to us about your specific fanout needs.

Typical specifications for fanouts are:

  • Average insertion loss per channel per fanout:
0.6 dB
  • Average crosstalk per channel:
< 40 dB
  • Polymeric package dimensions:
114 x 7 x 7 mm (135 mm long with strain relief boots)
