Subisu

Subisu, formally Subisu Cablenet Ltd., is a Nepalese internet service provider headquartered in Kathmandu. Established in 2000, the company developed as a connectivity and digital television operator serving residential, business, and wholesale customers in Nepal. Its principal activities include broadband internet access delivered through cable and fiber infrastructure, digital television, enterprise networking, managed services, and related telecommunications solutions. The company operates a hybrid fiber-coaxial network as well as fiber-based access infrastructure. Optical fiber is used to carry television channels and fiber connectivity, while the hybrid network combines fiber transport with coaxial distribution. Subisu has used metropolitan access networking, Multiprotocol Label Switching infrastructure, and redundant network design to support service delivery in and around the Kathmandu Valley and other parts of Nepal. Its cable broadband infrastructure has used DOCSIS 3.0 technology, a cable-modem standard designed for bidirectional IP traffic and channel bonding. Its service portfolio extends beyond consumer broadband. Listed offerings include enterprise internet, FTTH broadband based on GPON, WAN Ethernet, wavelength services using DWDM, Ethernet over SDH, wholesale IP transit, managed services, network security solutions, and digital television. This combination gives Subisu a role in both the consumer communications market and Nepal's business connectivity ecosystem. According to the cited reference material, Subisu had coverage in all 77 districts of Nepal and more than 235,000 customers as of 2023. The same material describes a workforce of more than 1,500 full-time employees, including technical and non-technical staff. Its principal network headend is located in Baluwatar, Kathmandu, with infrastructure extending across major locations in the Kathmandu Valley. Subisu's positioning is therefore that of a national fixed-connectivity provider combining broadband access, television distribution, and enterprise telecommunications rather than a narrowly focused internet reseller.

Subisu was established in Nepal in 2000 as an internet service provider and developed its business around fixed-line connectivity. The company is based in Kathmandu, where its network operations and principal headend are located. From its original internet-service role, Subisu expanded into a broader communications business serving households, organizations, and wholesale telecommunications customers. A central part of its infrastructure is a hybrid fiber-coaxial network. Fiber is used for transport and for carrying television and broadband traffic, while coaxial cable provides portions of the access network. The network incorporates MPLS and a redundant metropolitan access design, particularly across major locations in the Kathmandu Valley. Subisu has also deployed optical-fiber access for services based on metropolitan access networking and GPON-based fiber-to-the-home broadband. The company's cable network has used DOCSIS 3.0 technology. DOCSIS enables two-way transmission of internet protocol traffic over cable networks and supports downstream channel bonding, allowing multiple channels to be combined for higher capacity. In parallel with cable broadband, Subisu has offered FTTH services and other fiber-based connectivity products, reflecting the wider shift in the Nepalese market from legacy cable access toward higher-capacity optical-fiber connections. Subisu's business scope broadened beyond residential internet access. Its documented services include enterprise internet, WAN Ethernet, wholesale IP transit, managed services, network-security solutions, DWDM wavelength services, and Ethernet over SDH. It has also operated digital television services, including Digital Clear TV, pairing television distribution with its broadband network. This portfolio positions the company as an integrated fixed-network operator rather than solely a retail broadband brand. By 2023, the reference material described Subisu as serving more than 235,000 customers and having coverage across all 77 districts of Nepal. It also reported a workforce exceeding 1,500 full-time employees, with personnel divided between technical and non-technical functions. These figures indicate a substantial national operating footprint. No reliable source material supplied for this dossier identifies the company's founder, current executives, ownership structure, public listing, or a separate parent company. The available material also does not document major scandals, acquisitions, formal advertising campaigns, or dated strategic decisions, so those sections remain unpopulated rather than inferred.
