An access network is a type of telecommunications network which connects subscribers to their service provider. The access network may be further divided between copper wire or optical access network, and HFC or Wireless access network. Access networks around the world evolved to include more and more optical fiber technology. Optical fibre already makes up the majority of core networks and will start to creep closer and closer to the customer, until a full transition is achieved, delivering value added services over fiber to the home. Usually optical access network topologies refer to Point to Point (P2P) topology. They are tradition way, such as enterprise dedicated fiber link. PON is different than other optical network topologies in that it is a Point to Multi-Point (P2MP) topology, which is the leading technology being used in FTTx (FTTH) deployments. Any date transmitted from the OLT is broadcasted to all Optical Network Units (ONU). In contrast, ONU transmits data up to OLT via TDMA. Ethernet Over Cable is deployed in the existing CATV HFC network to carry out internet and CATV bidirectional networking reconstruction. It consists of master and slave. EOC Master is usually resided at optical node.

Fiber Optic Cable, also known as an optical fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building. Sopto provides different types fiber cables, indoor or outdoor cables, which can be used in different application like aerial type, direct buried and duct type. Sopto fiber optic cable took the first lead to pass the ISO 9001 quality system, ISO14001 environment management system, OHSAS18001 occupational health safety management system，and its fiber optical cable meet the requirements of European CE, RoHs, Chinese TLC.

The FTTx system consists of three parts: the central office equipment (OLT), the user terminal equipment (ONT), and the optical distribution network (ODN). As an important part of the FTTx system, ODN is the optical transmission physical channel between the OLT and the ONU. The ODN consists of five parts: the feeder segment, the cable distribution point, the wiring segment, the cable access point and the household segment. From the ODF rack of the central office room to the feeder section of the cable distribution point, as the trunk optical cable, to achieve long-distance coverage; from the distribution point of the optical cable to the wiring section of the user access point, the nearest optical fiber is allocated to the user area along the feeder cable. The user access point connects to the user terminal to achieve FTTH. The main passive optical components include Fiber Patch Cords, WDM, Splitter Distribution Box, Fiber Patch Panel, Outdoor Fiber Cabinet, Indoor Optical Distribution Frame, Fiber Terminal Box, Fiber Closure, Fiber Connector, Network Cabinet, etc.

Generally, only one light beam with one wavelength is transferred over a pair of fiber. The wavelength multiplexing technology provides the ability to transmit more light beams, each having different wavelengths, using the same optical link. Due to the fact that wavelengths do not interfere, single light beams can be separated from each other using simple filters. A laser serves as the source of light and light-sensitive diode as receiver unit. Wavelength multiplexing is differentiated in CWDM (Coarse Wavelength Division Multiplexing) and DWDM (Dense Wavelength Division Multiplexing) technology. Advantage: With the use of WDM, it is possible today to transfer nearly 1 Tbps (C-band) via one pair of fiber.

Sopto offers all kinds of optic fiber test equipment (visual fault locators, ON optical power meters, optical light source), tool kits (optic hand tool bags, FTTH quick termination kits anaerobic field termination kits), cable preparation tools (cable cutters, precision fiber cleavers), fiber cleaning solutions and fiber polishing equipment & consumables.
