Bi-directional optical transceiver
First Claim
1. A bi-directional optical transceiver comprising:
- an optical fiber for transmitting and receiving first and second optical signals;
a transmitter module for generating the first optical signal;
a receiver module for detecting the second optical signal;
a tap filter for splitting a portion of the first optical signal;
a monitor module for monitoring the magnitude of the first optical signal split by the tap filter; and
a wavelength selection filter disposed between the tap filter and the optical fiber for inputting the first optical signal from the tap filter into the optical fiber and the second optical signal from the optical fiber into an optical detector.
