Smart Campus Network Solutions Comparison

In the quest for an ideal educational technology network solution for Smart Campus, it is crucial to examine the drawbacks associated with traditional Ethernet and PON (Passive Optical Network) networks, two prominent contenders in the connectivity realm.

- Drawbacks of traditional Ethernet solution: Traditional Ethernet networks, characterized by their reliance on copper cabling, pose several challenges in the modern educational landscape. One primary limitation is the inability to achieve a passive ELV (Extra Low Voltage) room. Despite advancements, these networks still necessitate an ELV room on each floor, leading to an abundance of massive cables and occupied cable trays. The resulting infrastructure not only adds complexity to the network but also makes Operations and Maintenance (O&M) a cumbersome task.

- Drawbacks of PON solution:

While PON is a common all-optical network solution, it presents several challenges:

Maintenance complexity:PON utilizes horizontal cabling throughout buildings, which can complicate maintenance within Floor ELV rooms.

The use of optical splitters in PON infrastructure restricts bandwidth and introduces latency. This limitation becomes particularly significant after splitting the signal, making it unsuitable for bandwidth-intensive applications used in modern teaching environments. Splitting the signal with a 10G standard often results in insufficient shared bandwidth for educational needs.

Scalability limitations: Currently, commercially available PON solutions typically only support up to 10G standards. With the evolution of protocols towards 50G standards and beyond, the future development direction for traditional PON remains unclear. This can limit the scalability of the network for future growth.

Limited Application: Due to these limitations, PON is typically only implemented on a small scale in the access layer of campus networks. Additionally, some PON solutions rely on proprietary protocols specific to vendors, further restricting their use to access layers and limiting interoperability.

Smart Campus Network Solutions

In the realm of cutting-edge smart campus network solutions, the Simplified Optical Ethernet Solution 3.0 (SOE solution) by Ruijie Networks stands out, introducing a transformative approach with advanced Coarse Wavelength Division Multiplexing (CWDM) technology. This revolutionary system surpasses traditional PON solutions with a 1:8 split ratio by providing unmatched 1:1 dedicated bandwidth, redefining network efficiency standards in educational environments.

The advent of the CWDM era signifies a significant breakthrough. The bandwidth with the least transmission loss is divided into 16 channels spaced by 20 nm each. This strategic division allows for the transmission of various service signals through a single optical fiber, significantly boosting transmission efficiency by a remarkable eightfold. Here's the magic behind CWDM: The CWDM technology operates like a highway with multiple lanes. Each lane, or channel, uses a distinct wavelength of light, ensuring the signals don't interfere with each other – much like vehicles traveling in their own lanes on a highway. This ensures that the bandwidth doesn't decay over the transmission distance, unlike traditional solutions that use splitters.

By integrating CWDM technology, SOE solution optimizes each optical fiber's utility, facilitating the simultaneous transmission of multiple service signals. This not only enhances transmission efficiency but also minimizes cabling costs between the main equipment room and individual buildings. The result is a sophisticated network infrastructure that not only provides dedicated bandwidth but also ensures cost-effectiveness and streamlined connectivity. This solution emerges as a transformative option, offering educational institutions an innovative and efficient solution for their evolving network needs.

The SOE solution leverages Ruijie's transparent distribution devices throughout the all-optical network.
