Subisu Cablenet Ltd. is a Nepalese Internet Service Provider company located in Kathmandu, Nepal, and was established in 2000.^[1] Subisu employs over 1500 full-time employees, of which around 900 are technical and around 700 are non-technical. As of 2023, the company has over 235,000 customers. It has coverage in all 77 districts of Nepal. Subisu primarily provides cable and fiber internet and digital TV services through a hybrid fiber-coaxial (HFCC) network.^{[citation needed]}

Optical fiber cable (OFC) is used by Subisu to transmit TV channels and fiber connectivity. Its HFC network uses coaxial cable laid with MPLS (Multi-Label Protocol Switching) and a redundant metropolitan access network. The network's headend is in Baluwatar, Kathmandu, and spreads across major locations in the valley.^{[citation needed]}

Data over Cable Service Interface Specifications (aka DOCSIS) 3.0 is standard technology certified by Cable labs. The DOCSIS 3.0 (Annex B) standard provides 42 Mbit/s per channel (theoretically) and 37 Mpbs (practically) downstream per channel. Downstream can bond up to eight channels, which increases the downstream throughput up to (37 × 8) and 27 Mbit/s upstream bandwidth per channel. This is the standard cable modem protocol established by MCNS for bi-directional transfer of Internet Protocol (IP) traffic over cable. Subisu uses Metropolitan Access Network (MAN) technology for its optical fiber cable services.^{[citation needed]}
