There are two main broadband PON access technologies: EPON (Ethernet PON) and GPON (Gigabit PON). EPON is a standard proposed by IEEE's EFM organization. Its original intention is to move Ethernet technology to the optical network for implementation. Therefore, the main work of its standard is to complete the EPON MAC protocol. Many aspects such as QoS, DBA, OMCI, etc. It is handed over to each manufacturer for its own definition. Its characteristics are simple implementation and low cost, but another problem is that the standards are not perfect. Operators need to carry out a large amount of standard definition and improvement work, and promote product interoperability. For this reason, China Telecom Group A lot of work has been done on the definition and improvement of the EPON standard, making active contributions to the large-scale commercial use of EPON in China. . As a new generation of Gigabit PON technical standards proposed by ITU-T, GPON takes into consideration the operator's operational requirements when formulating the standards, and clearly defines all aspects, especially in multi-service bearing, DBA and OMCI. Detailed definition, and GPON supports a higher split ratio and longer transmission distance, which makes GPON more advantageous in supporting dense user access and long-distance coverage; currently EPON is mainly used in Japan, but in other regions, including In North America, Europe, the Middle East, and South America, operators prefer to use GPON to deploy the next-generation optical access network.
In response to the future development trend of optical access, Huawei launched the latest generation of all-optical access platform-MA5680T. As the flagship product of broadband access, MA5680T represents the future development direction of optical access: ultra-large capacity, full range of optical Access mode, rich remote ONU solution.
Large capacity
As a next-generation platform that supports all-optical access, the MA5680T has massive switching capabilities. Its switching capacity reaches 400G, the bandwidth of each slot is up to 10G, and it supports 20G of upstream bandwidth. MA5680T is the industry's first T-bit (1000G) broadband access product.
Supports a full range of optical access methods
MA5680T supports all current optical access methods, including: EPON, GPON, Gigabit optical Ethernet, and 100M optical Ethernet. Just insert different interface boards to support different optical access methods, various optical interface boards Can be mixed at will, providing operators with an extremely flexible optical access platform: can provide EPON and GPON access methods to achieve FTTX, and can avoid the risk of technology selection; can provide Gigabit optical Ethernet interface, As a DSLAM or switch optical aggregation equipment; can provide 100M optical Ethernet interface as high-speed access for large customers; MA5680T as an access layer fiber access aggregation platform, can provide operators with a wealth of fiber access methods, Meet the diverse access requirements of the access layer.
Rich remote ONU solution
Compatible with multiple optical access methods is a diversified remote ONU. Depending on the location of the fiber extension, the MA5680T can provide different types of ONUs, including family, corridor, outdoor, etc., to provide operators with complete FTTX solution. Especially for MDU equipment, the upstream supports EPON / GPON / GE interfaces, and the downstream supports ADSL2 + / VDSL2 twisted pair access. It cooperates with the MA5680T to realize the optical entry and exit, and provides high-speed broadband access on the existing copper network.
At present, the Huawei FTTx solution with MA5680T as the core is widely used in the world. ETIsalat, the largest operator in the UAE, has completely migrated the construction model from copper cable to optical fiber, and uses FTTH as the main user access mode. ETI-salat will be the next five years. Renovation and new construction of 1.2 to 1.5 million lines of FTTH users will be completed. As the main partner of ETIsalat, Huawei ’s MA5680T all-optical access solution has been rigorously tested and tested and has been commercialized in the UAE, which will help ETIsalat broadband to fully Enter the era of light speed access.
