BA PA LA optical amplifier EDFA

This series of products is EDFA with high flatness. The core device adopts high-reliability Pump laser, and uses unique APC (automatic power control) and ACC (automatic current control) circuits to make the output power stable and reliable; the unique optical path design ensures excellent optical path indicators; Different application scenarios can be used as power amplifiers, line amplifiers or preamplifiers.

The power amplifier (booster-Amplifier), after the combiner, is used to boost the power of multiple wavelength signals after the multiplexing, and then transmit it. Since the signal power after the multiplexing is generally relatively large, the power The noise figure and gain requirements of the amplifier are not very high, but they require a relatively large output power after amplification.

Line amplifier (Line-Amplifier), after the power amplifier, is used to periodically compensate the transmission loss of the line. Generally, it requires a relatively small noise figure and a large output optical power.

Pre-amplifier (Pre-Amplifier), which is in front of the demultiplexer and after the line amplifier, is used for signal amplification to improve the sensitivity of the receiver (in the case of optical signal-to-noise ratio (OSNR) meets the requirements, large input power can be suppressed The noise of the receiver itself improves the receiving sensitivity), the noise index is required to be very small, and there is not much requirement for the output power.
