The Ytterbium-doped Fiber Amplifier (YDFA) from BOX OptronicsTech is a high-performance optical amplifier designed to amplify laser signals in the 1030–1100 nm wavelength range. Utilizing ytterbium-doped fiber pumped by a semiconductor laser, this amplifier offers a wide range of applications, including optical fiber communication and sensing.

Key features of the YDFA include a wide operating wavelength range, high output power with adjustable levels, and low noise performance. The amplifier is available in both single-mode (Hi1060) and polarization-maintaining (PM980) fiber versions, catering to diverse application needs. It provides saturated output power options ranging from 17 dBm to 40 dBm, with a noise figure of 5.0 dB and polarization-dependent gain of less than 0.3 dB.

The YDFA is offered in two form factors: a benchtop model for ease of operation and a compact modular version for integration into larger systems. The benchtop version measures 260(W)×280(D)×120(H) mm, while the modular version is more compact at 125(W)×150(D)×30(H) mm. Both models feature FC/APC connectors and operate on AC 110–240V or DC 5V power supplies.

For control and monitoring, the YDFA includes a user-friendly front panel with buttons for adjusting pump current and output power. It also supports RS232 serial communication for remote operation. The amplifier operates within a temperature range of -5 to +55°C and a humidity range of 0–70%.
Ideal for applications requiring high gain and low noise, the YDFA is a versatile solution for enhancing optical signal strength.
