Passive optical network (PON) plays a vital role in providing broadband network access to end customers. It can transmit signals from one point to multiple points through optical fiber. It consists of optical line terminal (OLT), optical network unit (ONU) and optical distribution network (ODN). GPON and EPON are the most famous and widely used types of PON. Before understanding the mysterious xPON, let's take a brief look at EPON and GPON.
GPON is popular for its high bandwidth, multi-service and large coverage. It is considered to be an ideal technology for achieving full coverage of broadband network access. The maximum downstream and upstream rates are 2.5Gbps and 1.25Gbps respectively.
EPON is based on the IEEE standard of Ethernet. It supports 1Gbps and 10Gbps transmission. Compared with GPON, it is more cost-effective.
However, with the development of technology and the needs of the market, xPON has emerged. The application of xPON has played an important role in the upgrade of EPON to GPON, which has benefited users a lot.
XPON is the integration of GPON and EPON in hardware and software.
On the one hand, GPON has higher upstream and downstream rates than EPON. Based on the backward compatibility of hardware, the mode of GPON network is considered to be the standard of hardware indicators. For example, it provides a variety of services, including TDM, ATM, Ethernet and CATV, which is the same as GPON. There is also QoS guarantee.
On the other hand, the software will adopt the method of automatic detection and switching. EPON/GPON OLT will send network packets when ONU accesses. ONU cannot match the OLT mode and cannot analyze the network packet. At this time, the xPON ONU will automatically restart and switch to another mode after a few seconds. Registration is completed after the switch is completed.
The previous analysis of GPON vs EPON has concluded that both have their own advantages and disadvantages. However, now we only need to choose xPON instead of wandering between GPON and EPON, because xPON can identify them and switch modes.
In addition, the xPON system provides a unified network management platform to manage various business needs, supports full services including ATM, Ethernet, TDM, and provides strict QoS guarantees, and transmits downstream cable TV through WDM.
More importantly, it is well known that GPON is becoming more and more popular. If users want to replace EPON with GPON, xPON will help save a lot.
According to market demand, Tenkilometers has developed a variety of ONU products. If you are interested, you can consult us.
Our products can be applied to wide temperature environments and have powerful firewall functions. Compatible with mainstream OLTs such as Huawei and ZTE. The excellent performance of xPON, such as high reliability, easy management and configuration flexibility, has begun to attract people's attention. I believe it will be in the fiber access (FTTH, FTTP and FTTC) of homes or enterprises. Whether it is xPON or GPON/EPON, the function that meets your needs is your right choice.
