The EFA-series of benchtop EDFAs are repackaged versions of the high-performance optical amplifiers found in MPB's repeaterless-link telecom equipment. These wall-plug units include preamplifiers with high gain and near-quantum-limited noise figure, as well as power amplifier models with saturated output powers up to 23 dBm.

Both C-band and L-band models
Ultra-low-noise figure preamplifiers
Wide range of power amplifiers (up to 23 dBm)
Fast transient response
Variable gain
Mid-Stage access
Gain-flattened preamplifiers and power amplifiers
RS-232 interface

Power Amplifiers
EFA-P15, P18, P21, P23
These one- to three-pump boosters are ideally suited to calibration of instruments at high-power level and linearity checks.

Features
1525 - 1565 nm typical operational range
Up to 23-dBm saturated output power
Input & output isolators
Low noise figure
Front-panel readout and control

C-Band Gain-Flattened Amplifiers
EFA-P15F, P18F, P21F, & P22F
Flattened up to 40 nm, these units offer high output power in the C band for DWDM applications, with the same user-friendly features of their non-flattened cousins.

Features
Up to 1527 - 1567 nm flat-gain operational range
< 1-dB flatness over bandwidth with DWDM signals
Up to 22-dBm saturated output power
Input & output isolators
Low noise figure
Front-panel readout and control

PreAmplifiers
EFA-R35, R35/100, R35/130, & R35W
These popular models offer extremely high-gain and almost quantum-limited noise figure in one turn-key package.

Features
1542-1160 nm, 1530-1565 nm or 1570-1600 nm wavelength range
Near quantum-limited noise figure
Up to 45-dB small-signal gain
Output isolator (input optional)

L-Band Gain-Flattened Amplifiers
EFA-P15LF, P18LF, P21LF, & R35LW
Spanning the L band, these units offer flat, high gain for DWDM applications

Features
1570 - 1610-nm minimum flat-gain operational range
< 1-dB flatness over bandwidth with DWDM signals
Up to 21 dBm saturated output power
Input & output isolators
Low noise figure
Front-panel readout and control
