Product Overview
PL2000C CATV PON EDFA is a cost-effective design with improved internal mechanical and electronic structures. It has WDM PON combiner inside that integrates GPON signals (upstream 1310nm and downstream 1490nm) with CATV signals (1550nm) on the same fiber cable for Internet / data service. PL2000C CATV PON EDFA uses world-class pump lasers, such as the Lumentum brand, as its light source, which is high reliable and efficiency.
PL2000C CATV PON EDFA can control the operational condition and provide system information, as well as real-time monitoring and alert thresholds for this equipment, all via the front panel’s touchscreen LCD. This type of CATV PON EDFA offers excellent APC/AGC and ACC control, as well as effective ventilation and high-efficiency heat dissipation, ensuring long-term durability and dependability. PL2000C has an RJ45 connector that allows remote control of the unit using a Web browser or the SNMP protocol. PL2000C CATV PON EDFA is a flexible and cost-effective option for large-area distribution networks.

Technical FAQ: CATV PON EDFA
Q1: What is the main advantage of using a CATV PON EDFA with WDM?
A: Our FTTH CATV combiner amplifier eliminates the need for external WDM filters. By integrating the combiner inside the 1550nm EDFA, you reduce rack space, minimize insertion loss (≤1.0dB), and simplify cabling in 10G-PON and GPON networks.
Q2: Which pump laser brand does the PL2000C use?
A: To ensure carrier-grade performance, we use industry-leading Lumentum pump lasers. This provides superior stability and a longer lifespan compared to standard alternatives, especially in high-density port configurations.
Q3: How do the APC, ACC, and AGC modes differ?
A: APC (Automatic Power Control) stabilizes the output optical power level; ACC (Automatic Current Control) stabilizes the pump current; and AGC (Automatic Gain Control) maintains a constant optical gain. These modes allow technicians to optimize the unit for various network environments.
Q4: Can I manage the CATV PON EDFA remotely?
A: Yes. The unit features an RJ45 connector supporting SNMP v1/v2c and Web management. You can monitor input/output power, set alarm thresholds, and adjust settings via any standard web browser.
