  1. 1. GEPON ---- A dream for broadband access www.2fonet.com Tel/Fax: 0086 571 56838475
  2. 2. Why need FTTx—bandwidth <ul><li>Data bandwidth requirement </li></ul><ul><ul><li>Nowadays, normally SDTV need 2-4 Mb/s when transmitting in IP network. </li></ul></ul><ul><ul><li>HDTV need 5 times of the bandwidth of SDTV </li></ul></ul><ul><ul><li>Each static photo can reach the size as 1MB </li></ul></ul><ul><ul><li>The audio flow of 5.1 passage can reach ~380 kb/s </li></ul></ul><ul><ul><li>…… </li></ul></ul>
  3. 3. Why need FTTx — transmission length <ul><li>The typical length for transmitting system capacity of 1Gbps </li></ul><ul><li>The limited transmission length and bandwidth of current ADSL </li></ul>
  4. 4. GEPON structure GEPON - Gigabit Ethernet Passive Optical Networks fiber access technology is developing for point to multi-point application. It is a mature access technology based on ethernet. GEPON is composed by : OLT -- Optical Line Terminal ONU -- Optical Network Unit POS -- Passive Optical Splitter ODN -- Optical Distribution Networks

  7. 7. <ul><li>Uplink and downlink up to the symmetry bandwidth of 1Gb/s </li></ul><ul><li>Long transmit length, up to 10-20KM </li></ul><ul><li>Offer data, voice, and video, realize three in one network </li></ul><ul><li>Sustain max split ratio 1 : 64 </li></ul><ul><li>Multi-users use one fiber, save trunk fiber and launched cost </li></ul><ul><li>Low requirement of maintenance, the whole network uses passive fiber optic devices, no outdoor active devices </li></ul><ul><li>Low fiber loss, better anti-jamming ability </li></ul><ul><li>Adopt large quantity of chips with mature ethernet technology, easy to implement, lower cost </li></ul><ul><li>End user can get high speed bandwidth as 100/1000Mbps </li></ul><ul><li>Compatible with existing ethernet, no need protocol conversion </li></ul><ul><li>Relative standards are quite mature, like IEEE802.3ah </li></ul><ul><li>Offer good QoS guarantee for different operation, etc.. </li></ul>The advantages of GEPON
  8. 8. TUOLIMA GEPON products advantages <ul><li>High performance / price ratio —— Among all current same kind products, TUOLIMA GEPON products’ performance / price ratio is the highest. </li></ul><ul><li>Long transmit length —— sustain 27-29dB attenuation, if more than 802.3ah ( 26dB ) , the transmit length will be even longer. </li></ul><ul><li>Support complete layer 2 and 3 function —— OLT1000+ not only has layer 2 function, but also has complete layer 3 operation function. Decrease the higher layers’ pressure, offer better local management ability. </li></ul><ul><li>High density of ports ——1U has connect ability with 8 PON ports, standard 42U chassis can connect to 4096 ONUs. </li></ul><ul><li>High security —— Except offering 128 digits AES encrpytion tachniques, also offer powerful Access Control List (ACL) function, which will increase the network security. </li></ul>
  9. 9. TLM-OLT1000+ TUOLIMA TLM-OLT1000+ is a highly integrated OLT device. It is with 4 uplink port modules and 2 downlink port modules (each module with 4 port modules). These modules can be SFP module, and all are hot pluggable. 2 power modules, which can be back up. AC or SC is ok. This OLT can connect to max 256 ONUs. It is the preferred network access project of intelligent residential district, office building, and other dense users. TUOLIMA also offer 3 types of ONU, including currently main network environment application, which family and corporation prefer. TLM-ONU101--1 RJ45 port for data TLM-ONU404--4 RJ45 and 3 RJ11 ports for data and voice TLM-ONU804--4 RJ45, 3 RJ11, and 1 CATV port for data, voice and video For more information, please browse : http://www.tuolima.com
