STAR-CMC-1550 Characterisation of Fiber Modal Content
The STAR-CMC-1550 Characterisation of Modal Content uses the spatially and spectrally resolved imaging (S2) technique to identify the propagation modes of few-mode fibers. It consists of two different unit: a tunable laser and a receiver unit. The STAR-CMC-1550 allows to obtain the Differential Group Delay (DGD) for each propagation mode and the relative intensity, or Multipath Interference (MPI), compared to the most excited mode. Moreover, STAR-CMC-1550 allows to reconstruct the profiles and phases of the guided modes of the fiber under test.
Features & Benefits:
Measure fibers up to 400 µm in diameter
Measure hollow and solid core few-mode fibers
Reconstruction of propagation mode profiles and phase
Calculate the relative intensity of high order modes compared to the most excited mode
