Introduction

In the dynamic landscape of the banking industry, reliable and high-speed data transmission is crucial for seamless operations and secure communication between different branches. This solution explores a Leading-edge Data Center Interconnect (DCI) and Metro Wavelength Division Multiplexing (WDM) solution tailored to the specific needs of a banking client requiring 100GE and 10GE services between sites A and B, spanning a distance of 330km, with an optical amplifier relay point strategically placed in between.

The Challenge

The banking client faced the challenge of transmitting high-capacity data over a considerable distance without compromising on speed, reliability, or security. The traditional methods of achieving this goal often involved complex dispersion compensation techniques, leading to increased costs and potential points of failure.

The Solution

To address these challenges, the proposed solution leverages Sino-Telecom's STN6800-D16HE, a state-of-the-art DCI WDM product. This innovative solution enables the seamless transmission of 100GE and 10GE services, providing a reliable and high-performance network infrastructure.

Key Features of the Solution

STN6800-D16HE DCI WDM Platform:

● The core of the solution is Sino-Telecom’s STN6800-D16HE-I, a high-density WDM platform designed for Data Center Interconnect applications.

● This platform supports advanced modulation schemes, enabling the activation of two channels of 100G services, thereby achieving 200G service transmission.

Dispersion Compensation-Free Design:

● The STN6800-D16HE-I eliminates the need for dispersion compensation throughout the entire 330km line. This is achieved through advanced technologies, ensuring signal integrity and reducing the complexity of the network infrastructure.

Optical Amplifier Relay Point:

● To address the distance challenge, an optical amplifier relay point is strategically placed between sites A and B. This ensures signal strength and integrity, allowing for the seamless transmission of high-speed data over the extended distance.

DCI WDM Technology:

● The solution utilizes Sino-Telecom’s DCI WDM technology, providing a flexible and scalable architecture that meets the evolving needs of the banking industry.

● DCI WDM enables efficient bandwidth utilization, cost-effective scaling, and simplified management of the network infrastructure.
