Highly Scalable D7000 Series EDFA: Boosting Modern Network Performance
In today's rapidly evolving telecommunications landscape, the demand for high-bandwidth, efficient, and reliable optical networks has never been greater. As data centers and metropolitan area networks expand, the need for advanced optical amplification solutions becomes a critical factor in sustaining performance and scalability. The D7000 series of Optical Amplifiers, including the latest EDFA models—OA1825, OA1835, and OLA2525—are specifically designed to address these challenges. This article introduces the cutting-edge features of the D7000 series EDFAs and how they can simplify and enhance your network infrastructure.
D7000 Series Optical Amplifiers
The D7000 series includes three high-performance EDFA (Erbium-Doped Fiber Amplifier) models: OA1825, OA1835, and OLA2525. These devices are engineered to enhance the performance and reliability of optical networks by providing robust amplification solutions.
Figure 1. D7000 Series EDFA Overview
Built-in BA/PA and LA/LA
The hallmark of the D7000 series EDFA is its built-in BA/PA and LA/LA configurations, enabling seamless bidirectional amplification, significantly distinguishing it from single-direction EDFAs. This unique feature consolidates amplification functions into a single unit, streamlining network design, reducing the number of required amplifiers, and minimizing space and infrastructure costs. The integrated Pre-Amplifier (PA) and Booster Amplifier (BA) across the C band (1528~1568nm) simplify installation and maintenance, enhancing operational efficiency, reducing network management complexity, and lowering deployment costs while improving network reliability.
In contrast to traditional single-direction EDFA configurations, the Bidirectional Amplifier offers unparalleled advantages in operational flexibility and cost-effectiveness. By integrating bidirectional amplification capabilities into a single unit, operators benefit from simplified network architectures and reduced operational complexities. This strategic consolidation not only optimizes resource allocation but also future-proof network investments against evolving technological and operational demands.
Adjustable Gain
One standout feature of the D7000 series EDFA is its adjustable gain range of ±10dB, allowing for customization and flexibility. Operators can tailor the amplification to suit varying network requirements, effortlessly accommodating changes in network scale and demand. This dynamic gain adjustment ensures the EDFA can adapt to diverse transmission scenarios, from short to extended distances (0~120km). By optimizing signal strength dynamically, network administrators can ensure consistent and reliable performance, mitigate signal degradation, and enhance bandwidth utilization, thereby improving overall network resilience and customer satisfaction.

Embedded OSC
The D7000 series EDFA incorporates an embedded Optical Supervisory Channel (OSC), which ensures real-time monitoring of critical optical performance metrics such as signal wavelength, power levels, fiber optic link attenuation, and breakpoint testing. This continuous monitoring optimizes network reliability by enabling proactive issue identification and resolution. The OSC also includes a 1510nm network management channel for robust intra- and inter-site communication and features such as the MON port and Optical Time-Domain Reflectometer (OTDR) for access monitoring. These capabilities help maintain network stability, minimize downtime, and enhance overall network performance.
