1. EPON and GPON adopt different standards. GPON is more advanced and can transmit more bandwidth and carry more users than EPON.
2. The EPON standard is the 802.3ah of IEEE. The basic principle of the EPON standard is to standardize the EPON within the 802.3AH architecture and extend the MAC protocol of standard Ethernet to a small extent.
3, GPON standard is the ITU-TG.984 series standard, GPON standard formulation considers the support for traditional TDM service, continue to use 125ms fixed frame structure, in order to maintain 8K timing continuation.
4. In applications, GPON has a larger bandwidth than EPON. Gpon has higher service load and optical splitting capability, and can transmit larger bandwidth services.
5. Comparison of GPON and EPON protocol stacks EPON and GPON have their own advantages and disadvantages.
What is the difference between gpon and epon?
1. EPON and GPON adopt different standards. GPON is more advanced and can transmit more bandwidth and carry more users than EPON. GPON is derived from APONBPON technology in the early days of optical fiber communication, and developed from it, the transmission stream uses ATM frame format. EPON's E refers to Ethernet interconnection, so EPON was born to be able to connect directly and seamlessly with the Internet, so EPON's code stream is Ethernet frame format. Of course, in order to accommodate transmission over optical fiber, a layer of EPON-defined frame format is wrapped around the Ethernet frame format.
2. The EPON standard is the 802.3ah of IEEE. The basic principle of the EPON standard is to standardize the EPON within the 802.3AH architecture and extend the MAC protocol of standard Ethernet to a small extent.
3, GPON standard is the ITU-TG.984 series standard, GPON standard formulation considers the support for traditional TDM service, continue to use 125ms fixed frame structure, in order to maintain 8K timing continuation. To support multiple protocols such as ATM, GPON defines a novel encapsulation architecture GEM: GPONEncapsulationMethod. Data from ATM and other protocols can be mixed and packaged into frames.
4. In application, GPON has a larger bandwidth than EPON, with better service load and optical splitting capability. GPON can transmit larger bandwidth services to achieve more user access, and pay more attention to multiple services and QoS guarantee. The gap between GPON and EPON costs is narrowing.
5. Compare GPON and EPON protocol stacks
EPON and GPON have their own advantages. GPON is better than EPON in terms of performance metrics, but EPON has the advantage of time and cost. GPON is catching up. GPON is more suitable for customers with high bandwidth, multi-service, QoS and security requirements and ATM as a backbone network. For customers with cost-sensitive, QoS and security requirements, EPON becomes the dominant.
