Long before "fiber broadband" was a household phrase in Nepal, one Kathmandu-based company was already laying the cable that would quietly rewire how the country got online and watched television. This is the Subisu history in Nepal — a story of firsts, from the country's earliest digital cable TV signal to its first ISO-certified ISP status — and how a single cable operator grew into one of Nepal's most recognized broadband and enterprise connectivity brands.
Subisu's milestone timeline — from a 2000-founded cable operator to a nationwide fiber and enterprise network provider
When Was Subisu Established?
Subisu Cablenet Ltd. was founded in 2000 in Kathmandu, Nepal, making it one of the country's earliest cable-based internet and television service providers. At a time when most Nepali households were just beginning to encounter the concept of home internet, Subisu entered the market through cable television infrastructure — a strategic foundation that would later let it offer both internet and TV services over the same physical network, well before "bundled" connectivity became an industry norm.
Today, the company has grown into a major player with over 1,500 full-time employees — roughly 900 technical and 700 non-technical staff — and a customer base that has grown into the hundreds of thousands, with a network presence spanning all 77 districts of Nepal.
Subisu's First Major Milestone: First ISO 9001-Certified ISP in Nepal
One of Subisu's earliest and most significant achievements was becoming the first cable TV and internet service provider in Nepal to be certified ISO 9001 — a quality management standard that signaled a level of process discipline and customer service commitment unusual for a young telecom company in Nepal's developing market at the time. This certification wasn't just a badge; it represented a structured approach to service delivery that helped distinguish Subisu from a market otherwise filled with informal, locally-run cable operators. The company has since maintained and updated this certification over the years (including ISO 9001:2015), and has also added ISO 27001 certification, covering information security management — relevant given how much sensitive customer and network data an ISP handles.
Launching Clear TV: Nepal's First Digital Cable Television Service
Subisu holds the distinction of being the first company in Nepal to introduce second-generation Digital Cable TV service, branded under the call sign Clear TV. This was a genuine technological leap for the country — Clear TV delivered MPEG4 Standard Definition and High Definition channels broadcast to individual subscribers through a Set-Top Box (STB), secured using a Conditional Access System (CAS) over the existing cable network.
Before this, Nepali cable television was largely analog, with limited channel quality and no meaningful content security or subscriber management. Clear TV's digital approach brought a level of channel clarity, content protection, and viewing experience that set a new benchmark in the Nepali pay-TV market, and the Clear TV brand remains Subisu's IPTV product line to this day, now also delivered over fiber alongside its original cable infrastructure.
Building the Backbone: Nepal's First MPLS-Based Metro Network
Behind the customer-facing services, Subisu was also pushing infrastructure innovation at the network level. The company built what's recognized as Nepal's first MPLS (Multi-Protocol Label Switching) based, fully redundant Metro network — a critical piece of engineering that allowed Subisu to deliver both internet and television services reliably over the same optical fiber cable infrastructure, a genuine first for dual-play service delivery in the country.
This backbone investment mattered far beyond residential customers — it positioned Subisu as a credible infrastructure provider for enterprise clients needing serious network reliability, eventually expanding into services like Metro Ethernet, Enterprise VPN connectivity, IPLC services, and managed video conferencing solutions for major organizations across Nepal.
From Cable to Fiber: The FTTH Transition
As Nepal's broadband market matured and customer expectations for speed grew, Subisu transitioned its residential offering from its original Hybrid Fiber-Coaxial (HFC) network toward full Fiber to the Home (FTTH) service. This shift allowed the company to compete directly in the fiber speed race that came to define Nepal's ISP market in the 2020s, eventually offering tiered plans up to 650 Mbps under its "Super Raftar" branding, complete with dual-band 5GHz routers and bundled Clear TV subscriptions.
Alongside this, Subisu built out a substantial 400G DWDM (Dense Wavelength Division Multiplexing) core network, connecting to five border points with India through four major upstream providers, plus two border connection points with China — giving the company serious international bandwidth capacity to support its growing customer base and enterprise clients.
Recent Milestones: WiFi 6 and Continued Modernization
Subisu has continued evolving its residential offering well into the fiber era, introducing WiFi 6 service with a three-tier structure — Smart WiFi 6, Pro WiFi 6, and Elite WiFi 6 — giving customers access to newer wireless standards with higher speeds, lower latency, and better performance across multiple simultaneously connected devices, a meaningful upgrade for the increasingly device-heavy households of modern Nepal.
The company also expanded into data center services, having built a modular data center in Baluwatar, Kathmandu, equipped with advanced hardware and dual power backup systems — extending Subisu's role beyond residential broadband into Nepal's broader digital infrastructure ecosystem, including cloud services for enterprise clients.
Subisu Today: Scale and Reach
- Presence in all 77 districts of Nepal, reflecting one of the broadest network footprints among private ISPs in the country
- Over 1,500 full-time employees, supporting both residential and enterprise service lines
- Hundreds of thousands of customers across residential, SME, and large enterprise segments
- A diversified service portfolio spanning Home Internet and Digital TV, Enterprise Internet, Enterprise VPN, IPLC services, Data Center Services, and Cloud Services
- Continued ISO certification across quality management (9001) and information security (27001) standards
Why Subisu's History Matters for Today's Customers
Understanding where an ISP came from isn't just trivia — it offers real context for evaluating reliability and long-term commitment. A company with a 25-year operating history, multiple ISO certifications, and infrastructure investments spanning cable, fiber, MPLS, and data centers has demonstrably weathered Nepal's evolving telecom regulatory environment, technology shifts from analog to digital to fiber, and intensifying competition from rivals like WorldLink, Vianet, and NTC. For customers comparing ISPs today, that track record of "firsts" — first ISO certification, first digital cable TV, first MPLS backbone — reflects a pattern of being an early mover rather than a fast follower, which is worth factoring in alongside current pricing and speed comparisons.
