Introduction:

The unique nature of optical transmission networks necessitates unparalleled reliability in both optical transmission lines and equipment. The assurance of optical transmission network operations has gradually become a core focus for telecom operators at all levels.

However, in current network landscapes, issues such as fiber damage, line interruptions, power outages, and equipment failures significantly undermine the stability of transmission networks. These challenges exert immense pressure on customer satisfaction, operational efficiency, and line maintenance. The urgency to reinforce network protection is undeniable.

Sino-Telecom Solution:

Sino-Telecom's Optical Line Protection (OLP) system offers a robust and innovative solution to tackle these challenges head-on. The OLP system proactively monitors primary and backup optical fibers, effectively mitigating the risk of both routes being disrupted simultaneously. When a line interruption or sudden, significant attenuation of optical signals is detected, the system autonomously switches to the backup route, ensuring uninterrupted business operations.

Sino-Telecom's OLP optical protection system offers a diverse range of configurations, including 1:1, 1+1, BIDI (Bidirectional), and BP (Bi-Directional Protection). This adaptability ensures that the solution can seamlessly cater to a wide range of scenarios and meet the diverse requirements of various network setups.

Real-world Application Cases:

1) Sichuan Mobile's 10G SDH Optical Protection Solution:

Business Load: Single 10G SDH Wave In this scenario, the existing line faced considerable attenuation due to compensating 40KM dispersion and Power Amplification (PA). To mitigate this, the OLP protection solution was employed with BA modules added at both ends, ensuring seamless protection and enhanced stability.

2) Bangladesh Telecom's DWDM 1+1+1 Optical Path Protection:

Business Load: 12 Waves of 10G, 6 Waves of 2.5G In this notable application, the solution facilitated the seamless transmission of 12 waves of 10G and 6 waves of 2.5G between Dhaka and Cox's Bazar over a distance of 600km, serving six sites. The system implemented three routes for 1+1+1 protection, ensuring the continuity of critical communication pathways. (Note: The diagram depicts only a subset of the actual implementation).

Conclusion:

Sino-Telecom's OLP Optical Protection Solution has emerged as a key enabler for enhancing the resilience and reliability of optical transmission networks. With its real-time monitoring, automatic switching, and adaptable configurations, Sino-Telecom empowers telecom operators to fortify their networks against disruptions, ensuring uninterrupted services to their customers. The successful application of Sino-Telecom's OLP solution in scenarios such as Sichuan Mobile and Bangladesh Telecom stands as a testament to its effectiveness in safeguarding critical communication pathways in diverse network environments. As the network landscape continues to evolve, Sino-Telecom's commitment to innovation and reliability remains steadfast, shaping the future of optical transmission technology.
