Subisu is Bringing 400Gbps Optical Fiber Network All Across Nepal


    • Subisu has deployed 400Gbps single optical fiber network
    • The ISP has partnered up with Nokia for the service switch implementation
    • The collaborative project will improve the internet quality and lower the operation cost

    Subisu Cablenet has installed a 400Gbps single optical fiber channel. The leading ISP of Nepal had been working with the global tech company Nokia for the network implementation. Subisu aims to extend the super high speed fiber solution all across the country from east to west. This project will be a big milestone to meet the internet requirements of Nepalese users.

    Subisu’s 400Gbps Single Optical Fiber

    The high speed optical fiber solution will significantly boost Subisu’s broadband offerings. The ISP can now exceed the expectation of its business and retail consumers and meet their high speed internet demand. It will enhance the quality of both the internet and intranet services.

    The 400Mbps single fiber channel will substantially uplift the fiber capacity resulting in low cost for operation. This can help Subisu deliver a multi-terabit capacity network through a single fiber. The customers can take advantage of the high speed and high quality broadband service and use it to the full extent.

    In Collaboration with Nokia

    Subisu has implemented the Nokia 1830 Photonic Service Switch (PSS) platform. The switch supports Photonic Service Engine (PSE) and Dense Wavelength Division Multiplexing (DWDM). It turns standard WDM (Wavelength Division Multiplexing) into a flexible transport layer with managed agile photonics, multilayer switching, and services, plus network intelligence. The ascendable switch enables rapid service deployment, lowers TCO (Total Cost of Ownership), and extends life cycles of the network

    Vinay Mohan, the CEO of Subisu said they had been working with Nokia for a long time. He also stated that Nokia’s industry-leading products and solutions will be helping to offer an extensive quality service to Subisu’s customers. As mentioned by Mohan, Nokia is the sole vendor for this important project and its solutions have enabled Subisu to provide customers with a high level of experience and service through our services.


    There are multiple factors to consider when it comes to quality internet. Good connection with high speed bandwidth is one of the most important elements. Internet Service Providers and other business Companies like Chaudhary Group and DishHome have already introduced their fiber net services. Such healthy competition between different companies is playing an important role on improving the overall internet quality and enrich customer satisfaction.
