Fiber optical splitters

Fiber optical splitters for multimode applications

LEONI Fiber Optics utilizes a photolithographic chip technology to develop and produce planar lightwave circuits (PLC).

Your advantages at a glance

  • Broadband transmission spectrum from 400 nm to 1,700 nm
  • Extremely low backscattering (important for metrology applications)
  • Low insertion loss
  • High reproducibility
  • Good uniformity for the individual outputs
  • Customer-specific input/output ratios
  • Customer-specific connector variants
  • Customer-specific housing designs

Range of products and services

Product portfolio

  • Multimode splitters for 50 µm, 62.5 µm, 100 µm, and 200 µm
  • Standard splitters (available for sample inquiries – see ordering options)
  • PLC designs available as standard
  • Feasible PLC designs
    • We are happy to develop new, customer-specific designs. The number of inputs can be varied here. The number of outputs must be a power of 2 (2, 4, 8, 16, 32,…).

Product properties

  • Very low insertion losses
  • High uniformity
  • High extinction rate

PLC design

A PLC consists of a chip and two fiber arrays. The chip is the primary component in any PLC. The chip contains the waveguide structures that are needed to combine and/or split the waveguides. The fiber array affixed to the chip front connects the chip inputs and outputs with the fibers. This flexible technology means that almost any input/output ratio is feasible (see product portfolio).
