**Subisu Cablenet Ltd.** is a Nepalese [Internet Service Provider](/source/Internet_service_provider) company located in [Kathmandu, Nepal](/source/Kathmandu), 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](/source/Digital_television) services through a [hybrid fiber-coaxial](/source/Hybrid_fiber-coaxial) (HFCC) network.[citation needed]

## Infrastructure

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

## Technology

Data over Cable Service Interface Specifications (aka DOCSIS) 3.0 is standard technology certified by Cable labs. The [DOCSIS 3.0](/source/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](/source/Bidirectional_transformation) of [Internet Protocol](/source/Internet_Protocol) (IP) traffic over cable. Subisu uses Metropolitan Access Network (MAN) technology for its optical fiber cable services.[citation needed]
