OPTICAL COMPONENT ASSEMBLY AND WAVEGUIDE LOOPBACK

An optical component assembly is provided including a substrate. The assembly includes an optical transmitter configured to transmit an optical signal, an optical receiver configured to receive the optical signal, and an optical waveguide extending between the optical transmitter and the optical receiver. The assembly further includes a frangible region defining a first portion of the substrate and a second portion of the substrate, wherein the frangible region is configured to allow the first portion to be separated from the second portion. The assembly may be configured to be modified from a testing configuration, in which the first portion is integrally connected to the second portion via the frangible region, to an operational configuration, in which the first portion is separated from the second portion such that communication of optical signals between the optical transmitter and the optical receiver is precluded.
