Optical component, built-in optical time domain reflectometer, and optical network device

A built-in optical time domain reflectometer, comprising an optical component, wherein the optical component comprises:

• a component base having a cavity, wherein a wave filtering sheet is provided inside the cavity;
• a transmitter module connected to the component base;
• a receiver module;
• and
• a pigtail,
• wherein the transmitter module is configured to transmit a first optical signal to the pigtail,
• wherein the receiver module is configured to receive a second optical signal from the pigtail,
• wherein the wave filtering sheet is configured to transmit the first optical signal transmitted by the transmitter module, to enable the first optical signal to enter the pigtail, and is further configured to reflect the second optical signal received by the pigtail to the receiver module, and
• a reflecting light guide through-hole is opened on the component base along an optical path direction that the light filtering sheet reflects the first optical signal.

An optical network device, comprising an optical component, wherein the optical component comprises:

• a component base having a cavity, wherein a wave filtering sheet is provided inside the cavity;
• a transmitter module connected to the component base;
• a receiver module;
• and
