C-band 26dB-gain EDFA module. Max power > 13dBm. Erbium-doped fiber amplifier.

C-band 26dB-gain EDFA module. Max power > 13dBm. Erbium-doped fiber amplifier.

Fixed 26dB-gain at small signal input and fixed >13dBm-output at large signal input. Low-cost and compact EDFA instrument for your lab experiment and project. It is based on high-reliable JDS 27-series 974nm pump laser and telecom-grade circuitry.

 

You need connect 4 wires (+5V, -5V, GND, +5V to enable EDFA) from your power supply. See 1st 2 photos. It comes with 26-pin cable with connector only at one end, see 1st photo. To save our labour cost, we only verify output power >13dBm at -1dBm input, no detailed test result. You can buy our power supply at  +5, -5V dual output linear power supply

SPECIFICATION:

 

Operating wavelength: 1529.16nm – 1561.84nm (You can use at wider wavelength range at lower gain and power performance).

Fixed gain at small signal: 26dB typical (min 24.5dB, max 26.5dB), at input signal between -19dBm and -13dBm.

(Gain will reduce gradually if input power decrease from -19dBm. Gain near 1562nm or near 1529nm might be slightly out of specification).

Fixed output power at >-13dBm input: 13dBm typical. Output power will be saturated and grow slower with input power after input power greater than -13dBm.

Max output power at large input (-1dBm ): >13dBm.

Noise figure at input signal between -19dBm and -13dBm : 5dB typical. Noise figure is a little bit high at shorter wavelength, up to 6dB. Noise figure would be higher at <-19dBm input.

Noise figure at large signal input: >5.5dB typical.

 

Gain flatness: <1dB typically, at >-19dBm input signal power. There is small gain peak at small input signal, and there is small gain peak at 1558nm at large input signal.

Note: Better gain flatness may be available by adding gain-flat filter at the input or output of internal EDFA module. We have many various gain-flat filter inventory for this.

 

PDG: 0.3 dB. Polarization Dependent Gain

PMD: 0.4 ps. Polarization Mode Dispersion

Traditional Transient Over/Undershoot/Offset (Po) / (Pu) / (Pos): ±0.5 dB. For 6 dB add/drop within 3.2 nm band; Defined as in note (4) (7)

On-OFF Transient Overshoot/Offset (Po) / (Pos) : ±1.5 dB From dark to -13 dBm input with rise time < 30 ns. Defined as in note (5)(7)

Transient Suppression Time (Tts): 20ns typical, 50 ns max. Defined as in note (6)(7)

Transient Settling Time (Tst) : 500 us. Defined as in note (4)(7)

Input/Output Return Loss: max 35 dB

Residual Pump Power at Output : <-25 dBm.

 

It can be used as pre-amplifier, line, and booster(post) amplifier

 

Operating modes: constant-gain at small signal input, constant-power at large signal input.
