In the rapid changing world of fiber optics broadband networks operators and system integrators, in last-mile deployments, are often confronted by GPON and EPON technologies dilemma. Traditionally, these were closed systems—one had to choose either GPON or EPON, and could not support both technologies on a single OLT unit. But the arrival of the technology called XPON (namely, an auto adaptive ONU) has changed this landscape completely. Today we will present why using an XPON ONU router is becoming more and more favorite in current telecommunication industry.
What is XPON and Why Does It Matter?
XPON combines both primary PON standards on the same platform–GPON (Gigabit Passive Optical Network) and EPON (Ethernet Passive Network). A Traditional GPON ONU/EPON unit can only interface with GPON OLT or EPON OLT respectively. If an ISP does not want to maintain two different inventory and also to save money to purchase devices at very lowest costs in any circumstances, the operator will find it difficult to adapt to different network technologies in his network.
The XPON ONU solves this problem by integrating into a single terminal, dual stacks of the GPON and EPON standards. An XPON ONU router supports a single protocol stack by automatically choosing GPON protocol or EPON protocol based on negotiation messages which are transmitted by OLT and the ONU unit itself during device's boot process. Then through its smart auto adaptive booting algorithm, the XPON ONU can seamlessly fit in different OLT type no matter it be a GPON OLT or an EPON OLT. Hence an XPON ONU router enables to deploy a homogeneous OLT and ONU network without any restriction for the choice.
The Power of Auto-Adaptive Technology
An auto-adaptive ONU features a smart booting process where it does not decide before power on. At the time the ONU starts, it will actively monitor the incoming optical signals and the negotiation messages from the OLT and load the correct protocol support by automatically downloading corresponding protocol stack and firmware into it.
For network operators who have mixed network architecture or who plan to transition from one protocol (GPON to EPON, or EPON to GPON), deploying auto-adaptive ONU can immensely simplify the management. For example, an ISP can run out of one kind of ONU for the network upgrade during OLT site transition. By deploying one of our Auto adaptive XPON ONU router, technicians can install it on site and it can automatically adapt to existing OLT type, providing the function of a plug and play device for on-site technical support, thus hugely lowering operational expense (OPEX) of inventory management and field operations.
Choosing the Right XPON ONU for Your Network
When selecting an auto-adaptive ONU solution, beyond GPON/EPON support, here are other factors to consider for building a robust, sustainable network:
Port Configuration: Modern auto-adaptive ONU device always comes with additional Gigabit Ethernet ports for the user (router functionality for home or SOHO), Wi-Fi. For the device you select, consider your end user requirements, such as how many network ports it needs and whether it needs to provide WIFi services to them.
WiFi Standards: What kinds of Wi-Fi technologies are your end-users expecting, whether Wi-Fi 5 or the latest Wi-Fi 6? These determine what performance and bandwidth that you can serve for your subscribers.
Quality and Manufacturing: A robustly engineered and consistently manufactured auto-adaptive ONU is crucial for minimal downtime for your subscribers. Having an auto-adaptive ONU that is reliably manufactured from robust components and with automated manufacturing process such as SMT line and rigorous Quality Control (QC) process is always your best bet.
Why Choose a Professional Manufacturer?
It is highly recommended to choose a professional Manufacturer as our company Shandong Wanshuo Optoelectronic Equipment Co., Ltd. The company has a strong capabilities in independent research and development and an intelligent manufacturing process. All products are developed and manufactured in China, including material raw procurement and entire manufacturing process, allowing for maximum control over the quality, which makes their auto-adaptive ONU router very mature and reliable, for example, its stability for diverse application environments is top-tier due to its self-manufacture capability from component to finished goods and stability of personnel and quality.
Conclusion
Auto-adaptive ONUs make the network design and logistics process and infrastructure choices seamless with no concern for future developments or changes required. Using an Auto adaptive ONU ensures not only simplified device deployment and costs are minimized but also better experience for customers. Look for manufacturers who invest in automated technology, with solid technical background when purchasing your auto-adaptive ONU.
