Infrastructure

Optical fiber cable (OFC) is used by Subisu to transmit TV channels, the internet, and fiber connect solutions. Its HFC network uses high end coaxial cable laid with MPLS (Multi-Label Protocol Switching) and a fully redundant metropolitan access network. The network's headend is at Baluwatar, Kathmandu, and spreads across major locations of the valley. Signals from the OFC is tapped at points of service using an optical node with devices which convert light signals into Radio Frequency (RF) amplified to the desired levels using high bandwidth.

Technology

Data over Cable Service Interface Specifications (DOCSIS) 3.0 is advanced standard technology certified by Cable labs. DOCSIS 3.0(Annex B) standard provides 42Mbit/s per channel (theoretically) & 37Mpbs(practically ) downstream per channel. Downstream can be bond up to 8 channels which increase the downstream throughput up to (37x8) and 27 Mbit/s upstream bandwidth per channel and is the standard cable modem protocol established by MCNS to describe protocol for bi-directional transfer of Internet Protocol (IP) traffic over cable. Subisu uses state of the art Metropolitan Access Network (MAN) technology to deliver quality internet/intranet and other services through optical fiber cables.

FTTH

Fiber to the home (FTTH) is the installation and use of optical fiber from ISP infrastructure directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access. FTTH supports high connection speeds available to end-users. It is used worldwide now to deliver data signals like Internet, IPTV etc.

gollark: This application is LITERALLY a particle of weight W placed on a rough plane inclined at an angle of θ to the horizontal. The coefficient of friction between the particle and the plane is μ. A horizontal force X acting on the particle is just sufficient to prevent the particle from sliding down the plane; when a horizontal force kX acts on the particle, the particle is about to slide up the plane. Both horizontal forces act in the vertical plane containing the line of greatest slope.
gollark: Fiiiiine.
gollark: I agree. It's precisely [NUMBER OF AVAILABLE CPU THREADS] parallelized.
gollark: > While W is busy with a, other threads might come along and take b from its queue. That is called stealing b. Once a is done, W checks whether b was stolen by another thread and, if not, executes b itself. If W runs out of jobs in its own queue, it will look through the other threads' queues and try to steal work from them.
gollark: > Behind the scenes, Rayon uses a technique called work stealing to try and dynamically ascertain how much parallelism is available and exploit it. The idea is very simple: we always have a pool of worker threads available, waiting for some work to do. When you call join the first time, we shift over into that pool of threads. But if you call join(a, b) from a worker thread W, then W will place b into its work queue, advertising that this is work that other worker threads might help out with. W will then start executing a.
