A cable assembly for optical monitoring is assembled by laying optical fibers into an adhesive layer on a substrate to form an optical circuit. First ends of the fibers are arranged in various groups and second ends of the fibers are arranged in various groups. Groups at a first end of the circuit are spliced to coupler input fibers and coupler output fibers. Groups at the second end of the circuit are terminated at one or more input connectors, one or more output connectors, and one or more monitoring connectors. Some cable assemblies monitor signals received at the input connectors. Other cable assemblies monitor signals received at both the input connectors and the output connectors.

A ferrule includes a ferrule matrix, an optical fiber, and a dielectric reflective film. The optical fiber is disposed in an accommodating through hole of the ferrule matrix, and the dielectric reflective film covers an optical transmission surface of the optical fiber and a surface that is of the ferrule matrix and that faces a matching ferrule. The dielectric reflective film has a through hole, such that the dielectric reflective film does not shield a main optical path area of the optical transmission surface of the optical fiber. A reflective band of the dielectric reflective film includes at least a part of a communication band of the optical fiber. In this way, when light from the matching ferrule is transmitted to the ferrule matrix and the optical fiber, the dielectric reflective film reflects the light.

An optical module includes first and second optical fibers, and first and second optical fiber collimators, that are arranged in a light path. The first optical fiber collimator has a first core and a first cladding layer surrounding the first core. The second optical fiber collimator has a second core and a second cladding layer surrounding the second core. The first optical fiber has a third core. The second optical fiber has a fourth core. When the third core has a diameter smaller than the fourth core, a refractive-index difference between the first core and the first cladding layer is larger than that between the second core and the second cladding layer. When the third core has a core diameter larger than the fourth core, the refractive-index difference between the first core and the first cladding layer is smaller than that between the second core and the second cladding layer.
