Difference between XPON from GPON and EPON

Время: 2022-09-29 Хиты : 28

When it comes to providing end users with access to broadband networks, Passive Optical Networks (PONs) are crucial. Over an optical fiber, it is capable of sending signals from one point to multi-point locations. The whole process is done through Optical Line Terminal (OLT), Optical Network Unit (ONU), and Optical Distribution Network (ODN). The most common and well-known types of PON are GPON and EPON. Let's review EPON and GPON before diving into the XPON.

 

EPON:   Ethernet passive optical network abbreviated as EPON. Computer network connections across telecommunications infrastructure are made possible by EPON. EPON uses Ethernet pack compared to GPON, who uses ATM cells. This is what differentiates EPON from GPON. EPON is used in FTTP and FTTH networks as a point-to-multipoint deployment. To establish a multi-point connection, EPON uses a single optical fiber channel. EPON delivers voice, video, and Internet access using Ethernet packets. 

 

For Ethernet, EPON is established on IEEE standards. When the matter comes on compatibility, EPON is completely compatible with other Ethernet standards. Hence no conversion or encapsulation is necessary when connecting to Ethernet-based networks on both ends. It can achieve transmission speeds of 1 Gbps and 10 Gbps without any problem. Compared to GPON, it's more cost-effective.

 

EPON provides:

 

  • 1 Gbps upstream and downstream data transmission rate

  • voice, video service, and Internet access

 

 

GPON: Gigabit Ethernet Passive Optical Network abbreviated as GPON. When it comes to voice, GPON uses ATM, while for data, it employs Ethernet, and when it comes to voice, it employs a proprietary encapsulation. GPON provides faster Gbps on Downstream and upstream speeds in comparison to EPON. GPON is made of new generations broadband standard of passive optical access. GPON is widely used in Fiber-to-the-home (FTTH) networks. 

 

GPON is becoming increasingly popular as a result of its high bandwidth, varied service options, and wide range of coverage. It is often considered to be the most suitable technology for achieving comprehensive coverage of access to broadband networks. Both the downstream and the upstream rates can reach a maximum of 2.5 Gigabits per second. Maximum 2.5Gbps and 1.25Gbps of downstream and upstream speeds are achievable. 

 

GPON provides: 

 

  • Maximum of 2.5 Gigabits per second

  • Complete business protection with Quality of Service (QoS) and top-tier security

  • Full OAM (operations, administration, and management) function responsibilities

 

However, xPON has emerged as a result of technological advancements and consumer demands.

The adoption of xPON makes a significant difference in upgrading EPON to GPON and greatly helps users.

 

What is XPON? 

Simply put, XPON combines GPON and EPON's technology and software.

Upstream and downstream speeds for GPON are greater than those of EPON. 

 

The GPON network mode is the benchmark for hardware indicators due to its backward compatibility. The many services it provides are TDM, ATM, Ethernet, and CATV (the same as GPON). QoS Guarantee is another option. The software, on the other hand, will switch to an automatic detection and selection mode. When an ONU requests network data, the OLT will send it to it through EPON/GPON. If the ONU and OLT are incompatible, packet analysis across the network will fail. After a few seconds, the xPON ONU will automatically restart and change over to the other mode. When the transfer is complete, registration is done as well.

 

 

  • XPON multi-service features have the capabilities to gain complete services such as ATM, Ethernet, and TDM. It comes with a strict QoS guarantee for business optimization. 

  • Supports multicast features 

  • The transmission distance allowance is 20KM. 



What are the advantages of XPON compared to EPON and GPON? 

As we can see from our comparison of GPON vs EPON, both technologies have their advantages and disadvantages. Instead of hesitating between GPON and EPON, we can now simply selectXPON, which will automatically detect the appropriate mode.

Кроме того,XPON system offers a centralized network management platform for handling a number of business needs, as well as full service support for ATM, Ethernet, and TDM with a guaranteed quality of service, and WDM transmission of downstream cable TV.

Everyone knows GPON is getting increasingly popular. If customers desire to switch from EPON to GPON,XPON will be a huge help.
