product description:

GSDT-EDFA optical amplifiers JDS, Fujitsu, Nortel, Lucent, Fitel and other world-leading semiconductor company produces a wavelength of 980nm or 1480nm high linearity, optical isolation, distributed feedback, thermoelectric cooling DFB laser as the pump source. Machine equipped with optical power output stabilizing circuit, laser thermoelectric cooler temperature stabilization control circuit and the predistortion circuit to ensure stable long-life optimum performance of the machine and the laser.

Features:

Digital panel displays the operating parameters (VFD).

The laser operating parameters deviate from the permissible range set by the software will automatically shut off the laser power supply, the red alarm, digital panel prompts cause of the malfunction.

Power through rational optimization software to minimize the EDFA NF, allows the system to obtain superior CNR.

High-performance switching power supply, can work in 85∽265Vac City Network Voltage, also optional DC48V power supply (reservations required). Chassis cooling automatic temperature control.

Option status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standards, enabling network monitoring capabilities.

Aluminum structure using plug-in switching power supply, is conducive to cooling and replacement. And dual power supply hot backup.

Adjustable output power range (-3dB), especially when the user ordering instructions.

Technical Parameters：

Ordering guide:

Common failure analysis:

1, when the machine is working plug pigtail, pigtail head burns, causing optical amplifier output power decreases. The proposed closure of optical amplifiers in the plug pigtail.

2, the wavelength of the light source of the deviation is too large, resulting in lower output optical power of the optical amplifier, panel displays smaller.

3, the input optical power is lower than the nominal value, resulting in lower output optical power of the optical amplifier, panel displays smaller.
