1、 Technical analysis

The 10G SR (Short Reach) optical module is designed for short distance, high-speed data transmission. ER (Extended Reach) debugging is usually carried out to ensure that the optical module can work stably over longer distances or under specific network conditions. From a technical perspective, canceling ER debugging means that the optical module will no longer undergo specific optimization and testing for long-distance transmission.

If the application scenario is indeed limited to short distance transmission and the network environment is stable, then canceling ER debugging is technically feasible. Because SR optical modules are designed for short distances, their performance parameters and stability are usually guaranteed over short distances.

However, if there is a need to expand transmission distance in the future, or if the network environment becomes complex (such as increased fiber attenuation, dispersion issues, etc.), optical modules that have not undergone ER debugging may face the risk of performance degradation or instability.

2、 Cost benefit analysis

Canceling ER debugging can save manpower, time, and equipment costs during the debugging process. This may be a significant savings for mass-produced and deployed optical modules.

On the other hand, if the lack of ER debugging in the future leads to poor performance of optical modules in specific scenarios or the need to replace higher-level optical modules, it may incur additional maintenance and replacement costs.

3、 Analysis of operational complexity

Canceling ER debugging simplifies the production process, reduces operational steps and testing steps, thereby reducing the complexity of operations.

But this may also increase the complexity of on-site deployment and maintenance in the later stage, as there is a lack of optimization and testing data for long-distance or specific network conditions.

4、 Potential risk analysis

The biggest potential risk is unstable performance. Optical modules that have not undergone ER debugging may exhibit instability or performance degradation under certain network conditions.

Another risk is compatibility issues. If other devices or modules in the network have been debugged by ER, the unmodified SR optical module may have compatibility issues with it.

5、 Conclusion and recommendations

In summary, it is technically feasible to cancel the ER debugging of the 10G SR optical module, especially in clear short distance application scenarios. But in the long run, this may bring potential performance and stability risks. Therefore, it is recommended to fully consider the future scalability of the application scenario, the complexity of the network environment, and the balance of cost-effectiveness before deciding to cancel ER debugging. If possible, consider implementing a flexible debugging strategy, such as conducting ER debugging only when needed, or varying degrees of debugging on different batches of optical modules to meet the needs of different customers.
