Claim Text:
1. An optical time domain reflectometer (OTDR) device, comprising: a connector guide configured to mate to an attachable fiber optic connector; a beam splitter disposed within the connector guide; a lens seal coupled to a bottom portion of the connector guide; a collimating lens in alignment with the beam splitter and sealed to a bottom portion of the lens seal to prevent external contamination; a transparent carrier coupled to a bottom portion of the collimating lens, wherein the transparent carrier has electrical pathways; an optical transmitter and optical receiver in alignment with the collimating lens and mounted to an underside of the transparent carrier and connected to the electrical pathways; and a transmitting and receiving circuit mounted to the underside of the transparent carrier and connected to the electrical pathways, a transmitter of the transmitting and receiving circuit configured to send a signal to the optical transmitter to cause the optical transmitter to send a pulse of light into an optical fiber of the attachable fiber optic connector, and a receiver of the transmitting and receiving circuit configured to receive a signal from the optical receiver, from a received pulse of light from the optical fiber of the attachable fiber optic connector; wherein a time domain reflectometry measurement is determined from a time difference between a sent and received signal.
