Will XG-PON 10G GPON enough for us?

Share

Based on the FTTH Councils statistics, there are more than 35.9million FTTH and FTTB subscribers in Europe Continent, even though we are still developing GPON or GEPON network, but we still would like to discuss whether 10G XG-PON could meet our bandwidth demand in the future. Currently, China Telecom, Telephonic, Verizon etc, the main telecom operators are deploying XG-PON network worldwide with HUAWEI, ZTE equipment. China Telecom’s second field trial of 10 Gbps XG-PON FTTH network design, and Verizon field trials XG-PON2 from Alcatel-Lucent), the company…

Základy FTTx

Share

Digitální účastnické přípojky xDSL na metalických místních vedeních se staly běžnou součástí života mnoha lidí. Vedle toho začíná postupně pronikat do podvědomí veřejnosti nová zkratka FTTx (Fiber to the …) označující řešení přístupových sítí na základě optických vláken. Základní přehled poskytl již článek Optické přístupové sítě a na něj navazující článek Optické přístupové sítě EPON a CWDM, který rozvádí dvě perspektivní koncepce, a sice koncepci pasivních optických sítí na bázi Ethernetu (zahájena již standardizace PON s rychlostí 10 Gbit/s) a na bázi hrubého vlnového dělení…

Development of passive optical networks (PONs)

Share

PONs have attracted great attention in recent years, also from standardization bodies. Once again, the primary organizations are ITU-T and the IEEE (Institute of Electrical and Electronics Engineers). The latter defined the “Gigabit Ethernet Passive Optical Network (GEPON)” back in 2004 in the standard IEEE 802.3ah1. It is well known and established under the name “Ethernet in the First Mile” (EFM). A symmetrical transmission procedure is used for EFM. It has identical transmission speeds of 1.25 GBit/s downstream (from the central office to the subscriber)…

Taking Copper to Greater Heights With Best Practices for Pair Bonding

Share

Today, more than 1 billion households are still connected to a copper line.1 As the reality of supporting HDTV and video in just about every room has become the norm and no longer a luxury, higher bandwidth for Triple Play Services (voice, data, and video) continues to see a growing demand. Leading telco service providers around the globe have struggled to keep up in the past until the introduction of pair bonding, a blessing from the DSL powers above. Through the early deployments of this…

GPON GEPON Comprehensive Comparison

Share

Initial PON (1990s) were based on ATM framing (APON, BPON), ATM-based BPON were inefficient, majority of traffic through the access network was IP traffic, Ethernet based PON (EPON), QOS-aware Gigabit Ethernet (GbE) (VLANs, prioritization, OAM) and integration with other Ethernet equipment, Gigabit-capable Passive Optical Network (GPON) proposed by FSAN members (Quantum Bridge et. al) – dual Gigabit speed ATM/Ethernet PON to IEEE 802.3ah – had to continue this work within the ITU. EPON and GPON both draw on G.983, the BPON standard, (PON operation, ODN…
