Technical FAQ: PL2000A GPON WDM EDFA
Q1: How does the WDM function work in this GPON EDFA?
A: The PL2000A includes internal WDM filters that combine the 1550nm CATV signal with the 1310/1490nm data signals from your OLT. This allows a single fiber to carry both video and high-speed data to the end-user (ONU/ONT).
Q2: What is the insertion loss for the GPON pass-through ports?
A: We have optimized the internal structure to ensure a very low insertion loss of ≤1.0dB for the GPON channels, maintaining high signal integrity for your data network.
Q3: Can I monitor back reflection via the web interface?
A: Yes. The PL2000A identifies failed channels by monitoring back reflection. You can view these status reports and set alarm thresholds through the Web GUI or SNMP remotely.
Q4: Is it compatible with different OLT brands?
A: Absolutely. Our GPON EDFA is brand-agnostic and compatible with all major OLT manufacturers (Huawei, ZTE, Nokia, etc.) that use standard 1310/1490nm wavelengths.
