AI Technical Summary
In the existing technology, single-fiber unidirectional polarization-maintaining fiber amplifiers cannot achieve bidirectional transmission and amplification of optical signals.
A single-fiber bidirectional polarization-maintaining fiber amplifier is used. By combining the first and second polarization beam splitters PBS1 and PBS2 with the gain amplification unit, bidirectional transmission and amplification are achieved through the conversion of optical signals between the fast axis and the slow axis. Panda-type polarization-maintaining fiber and polarization beam splitter prism are used for beam separation and coupling.
It achieves stable bidirectional transmission and full gain of optical signals, avoids interference and interference between forward and reverse signals, and constitutes a fully polarization-maintaining fiber system.
