Optical fiber is a new technology, it converts the data into light impulses and sends them online. At destination, the impulse of light is converted into data. Because of small losses online and because the data transmission is done by impulse of light, the fiber may be used for greater distances without the need of Repeater. Fiber bandwidth can be 100Mbps, 1Gbps, 10Gbps, but it depends on the accessories you put online. There is no interference in optical fiber lines. Physical dimensions of the fiber are very small allowing easy installation, for large capacity.
Video in the context of IPTV, is the first application for fiber and is best accomplished with GEPON technology. Local loop with optic fiber built with a PON architecture is the best solution to provide video services, high speed Internet and VOIP.
A a 32 splits GEPON system can provide 30 Mbps symmetric connection, video and data. Bandwidth for VoIP is 64K per stream, while the Internet 128 Kbps, 384 Kbps, 512 Kbps and 1 Mbps downstream. Total bandwidth for all these three services is less than 25 Mbps.
GEPON is the technology that supports triple-play services today.
GEPON system is designed for telecommunications uses. GEPON equipment comply with IEEE802.3ah. These series of products are integrated, flexible, easily manageable and provide a high QoS. Fiber network’s speed reaches 1.25Gb / s and each EPON OLT (Optical Line Terminal) system can distribute 32 ONU (Optical Network Unit) to build a fiber network with maximum 32 splitter having the advantage of a high-capacity transmission, assuring high flexibility in the construction of the network, which telephony, Internet and IPTV can be accessed with.
Full compliance with IEEE 802.3ah, IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z, I EEE 802.1d, I EEE 802.1p, IEEE 802.1q, IEEE 802.1X, RFC1155, RFC1157, RFC1112, RFC1113.
Switch’s capacity: 16G
GEPON is the perfect combination of technology, Ethernet and passive optical fiber. It eliminates the use of active optical fiber between the OLT and ONU. This cuts costs and makes networks more easily maintained. GEPON uses WDM technology 1Gbps bandwidth up to 20km distance.
