Technical FAQ: PL2000B GPON EDFA Combiner
Q1: How does the GPON EDFA simplify headend architecture?
A: The PL2000B GPON EDFA functions as both a high-power amplifier and a combiner. By integrating the WDM PON combiner internally, it eliminates the need for hundreds of external patch cords and separate WDM filters, saving up to 70% of rack space and significantly reducing insertion loss.
Q2: What protection features are included for the pump lasers?
A: To ensure long-life reliability, the PL2000B includes an Automatic Pump Shutdown mode. If the optical input signal is lost or falls below the threshold, the pump lasers automatically power down to prevent damage, restarting instantly once the signal is restored.
Q3: Is the output power adjustable for different network scales?
A: Yes. The PL2000B offers adjustable output power ranging from -10dB to +0.5dB relative to the nominal output. This flexibility allows network engineers to fine-tune the signal levels for different fiber distances and splitter ratios directly through the Web or SNMP interface.
