Video HSBB

What is HSBB?

High Speed Broadband (HSBB) is a broadband service that offers bandwidth delivered at network speeds of 10Mbps and above when compared to normal broadband (Broadband to the General Population (BBGP)) which delivers bandwidth through wired and wireless technologies at network speeds ranging between 256Kbps and 4Mbps. Eventually in Malaysia, we will see basic HSBB packages offering network speeds between 20-50Mbps and up to 100 Mbps for consumers while businesses will have maximum network speeds available up to 1,000Mbps (1Gbps).

Technology

Modern fiber-optic communication systems generally include an optical transmitter to convert an electrical signal into an optical signal to send into the optical fiber, a cable containing bundles of multiple optical fibers that is routed through underground conduits and buildings, multiple kinds of amplifiers, and an optical receiver to recover the signal as an electrical signal. The information transmitted is typically digital information generated by computers, telephone systems, and cable television companies.

Fiber-optic communication


Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world.
The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.
