The dry insert also includes a plurality of particles having an average particle size of about 600 microns or less for inhibiting microbending.
Advantageously, the optical cable (100) is water-blocked and the water swellable yarn (4) does not induce microbending effects on the transmission elements (3).
Bending loss, microbending loss: Loss in fiber caused by stress on the fiber bent around a restrictive radius.
Since the increase of the microbend loss is effectively suppressed and the fiber diameter is below 200 νm, the probability of rupture due to bending strain does not practically bring up any problem.
An optical fiber having both low macrobend loss and low microbend loss.
The optical fiber has low bend losses, especially low microbend induced losses.
The sensor assembly is attached to the probe assembly for detecting said microbend of the optical fibre.
Both three-coating and four-coating systems are described that afford improve microbend performance.
The optical fibre and the body of material are in communication such that a volumetric change in the body of material causes a microbend of the optical fibre.
