| titleOfInvention | Multi-input multi-output optical fiber amplifier |
| abstract | The utility model discloses a many input many output fiber amplifier comprises N amplification branch road and drive control unit. Each amplification branch comprises 2 1 multiplied by 2 optical fiber couplers, 3 optical fiber isolators, 4 wavelength division multiplexers, 2 sections of erbium-doped optical fibers and 1 optical fiber splitter. The drive control unit comprises 2N photoelectric detectors, 2N logarithmic conversion chips, an analog-to-digital converter, a microcontroller, a digital-to-analog converter, N drive chips, N pump lasers, N1 multiplied by 2 optical switches and an N multiplied by N optical fiber coupler. The utility model provides a solution that narrow and small size is extensive (i.e. multiple input multiple output) enlargies for every branch road of enlargiing all possesses two branch roads of main pumping and backup pumping, reaches two way pump laser and each other is the function of backup, and has the characteristics of low power dissipation. |
