The optical amplifier uses the well-known high-performance erbium-ytterbium co-doped double-clad
fiber and low-noise pump laser. It has reliable circuit design and efficient heat dissipation design. The
maximum total output power of the whole machine can reach+37dBm, supporting up to 16 outputs,
including optical switch, CWDM and RF detection. It is applicable to the amplification and transmission
of 1550nm optical signal in the downstream of FTTH network.
EDFA uses modular and erbium-doped fiber amplification technology. Support laser switch function and
output optical power automatic power control (APC) function. The output optical power is ≥ 20dB, and
the output power of the optical amplifier can be adjusted, which can float down 0-3dB, as the system power
reserve. It is continuously adjustable at 0.1dBm step interval within 0-3dBm.
EDFA characteristics
● 3~+10dBm wide input range.
● The maximum output total power is 20dBm, with 8-port output.
● Excellent noise coefficient and nonlinear index.
● The keys on the internal display screen provide parameter reference and setting
● Cast aluminum waterproof shell, IP67 protection grade, excellent heat dissipation performance.
● The switch power supply with high reliability can adapt to the harsh outdoor environment.
Note: The optical signal of the downstream network is amplified and transmitted in the FTTX network.
One channel of input CATV 1550nm signal, eight channels of input OLT PON 1490nm signal, and eight
channels of output combined optical signal ports are connected to the user terminal ONU through the
ODN network respectively.
