Triple play solution

Triple play solution

Based on demand and existing technology, Raytrans provides EPON+EOC solutions for customers to achieve triple play integration.

Raytrans is based on building a new generation of optical access networks, targeting the bandwidth needs of the transformation of the broadcasting and television two-way network and the continuous growth of the access layer. It provides various capacity OLT central end devices and a series of ONU user end devices to adapt to various application scenarios such as FTTx, meet the equipment requirements of the three network integration, and fully meet the needs of operators to quickly and conveniently carry out high bandwidth and multi service in the fiercely competitive and rapidly changing business environment, achieving "three network integration".

The so-called "triple play" refers to the mutual penetration, compatibility, and gradual integration of telecommunications networks, broadcasting and television networks, and computer communication networks into a unified information and communication network worldwide, achieving the sharing of network resources, avoiding low-level redundant construction, and forming a multimedia infrastructure platform with wide adaptability, easy maintenance, and low cost for high-speed broadband.

FTTx involves many technologies, including optical devices, optical transmission systems, fiber optic cables, installation, maintenance and monitoring. Among them, transmission technology and equipment are key, and EPON/GPON technology is widely recognized as one of the best technologies for implementing FTTH. Passive Optical Network (PON) technology is a point to multipoint fiber optic access technology, as shown in Figure 2, which consists of an OLT (Optical Line Terminal) on the central office side, an ONU (Optical Network Unit) on the user side, and an ODN (Optical Distribution Network). The so-called 'passive' refers to the fact that ODN does not contain any active electronic devices or electronic power supplies, and is entirely composed of passive devices such as optical splitters, resulting in lower management and maintenance costs.

EPON (Ethernet Passive Optical Network) is a new broadband access technology that adopts a point to multipoint topology structure, uses fiber optics and optical passive devices for physical layer transmission, and provides multiple services through Ethernet protocol. It is a multi-user shared system. EPON fully combines the advantages of passive optical network technology and Ethernet technology, with features such as simple topology, low equipment cost, and no active devices between the central office and the terminal. The topology of EPON network is similar to that of cable TV network, which can directly carry data using the fiber optic lines of existing Cable TV network, saving the construction cost of data network. It has become the preferred broadband access technology for the integration of broadcasting and television networks.

EOC is a general term for Ethernet data transmission technology over coaxial cables. Its working principle is to use the existing cable television coaxial cable network to add Ethernet data channels outside the cable television transmission spectrum, so that the same coaxial cable can provide video, data, and voice services to users simultaneously. It transmits cable television and data signals in the downstream direction and data signals in the upstream direction, providing a return channel for bidirectional digital television platforms.

Raytrans EOC products have strong network adaptability, without adding wiring, changing existing coaxial cables and equipment, and not affecting cable TV signal transmission. They all support smooth upgrades, providing low-cost, operable, and easy to maintain solutions for network transformation.

Raytrans EOC products comply with the HomePlug BPL standard, utilizing the idle low-frequency band of 2-30MHz in HFC networks to transmit data services, perfectly separating cable TV signals and data signals, and using OFDM (Orthogonal Frequency Division Multiplexing) technology to enhance the system's anti-interference ability; And by introducing point to multipoint communication control technology, Ethernet data can be carried bidirectionally in a point to multipoint coaxial access network, providing an efficient and stable solution for the transformation of broadcasting and television bidirectional networks

Three in one all-optical solution:

This solution integrates cable TV signals with Ethernet data and telephone services at the central end, and transmits them to the user end through fiber optic cables. At the user side terminal equipment, fiber optic access is directly used to transmit Ethernet, telephone, and IPTV data to the user end, simplifying the network structure and improving transmission efficiency. It can be used for all-optical network access in new residential areas.

Topology description: At the central end, the PSTN and network are connected to the IDM-E8500 equipment, and the WDM equipment is connected through the PON port. The broadcasting and TV services are connected to the WDM equipment through optical fibers, and after multiplexing, they are output from one optical fiber. After reaching the user building, multiple optical directions are split using a splitter. The fiber optic system laid in the building is connected to each office and connected to the terminal equipment IDM-E3000. The equipment has one PON/ATV interface, four sets of 100M Ethernet interfaces, one channel of CATV RF signal output interface, and two channels of voice interface, thus achieving three network integration to the user end.
