Although it has been a valid option for many years, the use of fiber-optics was, until recently, limited to core networks of telecommunications providers and large enterprise groups, which was a niche market.
However, with the advent of the increasing need of bandwidth capacity for multimedia content, both in the Internet and IPTV networks, traditional communications systems based on coaxial cable and copper began to show functional and quality constraints.
This led to large-scale deployment of fiber-optic networks, in which the final connection to the subscriber’s premises is optical fiber, commonly known as FTTH (Fiber To The Home).
FTTH networks’ deployment multiplied the need for optical components and equipment, as well as their complexity.
Thus, PON (Passive Optical Network) networks are replacing ADSL access and coaxial cable, allowing for multiple bandwidths with higher capacity.
When it first started, Optilink positioned itself as a local supplier of fiber-optic cables for data centers, commonly known as ‘optical patch cords’. Since then, the company has steadily grown and it now produces a wide range of optical cables for other equipment, such as drop cables, breakout cables and pigtails, and for all the environments, namely optical rack cabinets, among others.
Today, there are three technologies being used in FTTH networks:
BPON – Broadband Passive Optical Network Standard. Despite being based on APON, it added capacity to WDM (Wavelength Division Multiplex), enabling a more dynamic upstream allocation, although with limited bandwidth.
EPON or GEPON (Ethernet Passive Optical Network) Standard. It uses Ethernet protocol for packet data transmission.
GPON (Gigabit Passive Optical Network). Standard Evolution of BPON. It supports higher information transfer rates with greater security. GPON is the technology on which most of the upcoming networks will be based on.
Optilink provides all the components for passive optical networks, no matter the chosen protocol.
