1.Overview

   With the development of social informatization, people have more and more demand for information, such as high-definition TV, 3D gaming, cloud computing, big data, IoT, cloud storage, etc., and new applications emerge one after another. The explosive growth of data volume will inevitably lead to higher requirements for network bandwidth capabilities. The access network closest to users often becomes a bottleneck, and the upgrade of the access network is imminent. The original copper access (ADSL or Cable Modem) has been unable to meet the high bandwidth requirements of current users.

   FTTH is fiber-to-the-home, with fiber as the transmission medium, which can provide users with higher bandwidth to meet the needs of diverse voice, video and data services. It will gradually replace other copper access technologies. PON (Passive Optical Network) refers to Passive passive devices from the central office to the customer end. It does not contain any active devices. This technology is recognized as the best FTTH access technology in the industry because of its high bandwidth and stable network. The advantages of convenience, easy management and maintenance, and low cost have been recognized by major operators around the world and are the preferred solution for access networks.

   Focusing on the development of PON technology and products, ANTEK has a rich PON product line that provides end-to-end product solutions.2.Technology & Solution.

2. Technology & Solution

   PON (Passive Optical Network) is a P2MP (point to multiple point) network system. It consists of three parts: an OLT (Optical Link Terminal), an ODN (Optical Distribution Network), and an ONU (Optical Network Unit).

   The PON network uses WDM technology to realize the uplink and downlink optical signals transmitted on the same optical fiber. The downstream optical signal has a wavelength of 1490 nm and the upstream optical signal has a wavelength of 1310 nm. Data transmission uses downlink broadcast, uplink time division multiplexing (TDM) technology to complete point-to-multipoint communication.

   At present, the mainstream solutions of the PON access network include GPON (Gigabit-Capable PON) and EPON (Ethernet Passive Optical Network). The PON standardization organization IEEE, ITU-T/FSAN researches EPON and GPON technologies respectively and outputs relevant standards.

FTTH solutions and products

   ANTEK provides a new generation of passive optical network product solutions based on PON system network FTTH solutions, complying with international and domestic related GPON and EPON standards, and meeting the transmission requirements of high-speed Internet, voice and video services. The solution can provide the last mile of fiber access for all kinds of network operators; it can also be applied to professional networks of customers in various industries, such as radio and television access networks, video surveillance networks, enterprise LANs, etc., serving radio and television, transportation, Customer-specific networks in the energy, power, finance and government industries.
