Quality
Assurance:
| Insertion
loss and Return loss |
Insertion loss
is the lost associated with a mated connector pair. Return loss is
defined as the ratio of light reflected at the mated connector pair
over the incident light. Both the Insertion loss and Return loss are
given in logarithmic scale. All patchcords are 100% tested for insertion
loss and return loss. |
| Geometric
Requirements |
An advanced
non-contact interferometric technique (DORC) is employed to measure
the geometric parameters of the polished enface. The key parameters
include radius of curvature, fiber height, apex offset, fiber and
ferrule roughness. Geometric requirements are important to maintain
the physical contact between mated connectors.
