Combo PON Has Become the Principal Solution for 10G GPON Construction

Date: 2023-03-16 15:44:00

 At present, more operators worldwide have carried out the 10G-GPON deployment and upgrade to meet the requirements of the gigabit user markets. In the global market, optical broadband access development has entered the Gigabit era. Combo PON is the mainstream large-scale commercial deployment solution for the upgrade of GPON to 10G GPON.This article will provide some knowledge about Combo PON.
\
Combo PON Technical Implementation
Combo PON is a combination of GPON and 10G GPON. It is a built-in optical multiplexing scheme that supports the coexistence of XGS-PON, XG-PON, and GPON ONUs. It is also called "three-rate Combo PON" and is recognized in the industry as the best solution for a smooth upgrade from GPON to XGS-PON.
Because XGS-PON and GPON use different wavelengths, three-rate Combo PON multiplexes the two types of wavelengths in an optical module, thereby achieving separate transmission and reception of GPON and XGS-PON signals. The three-rate Combo PON optical module has an embedded multiplexer, called the WDM1r, to combine and divide four upstream and downstream wavelengths needed by XGS-PON and GPON. XGS-PON and XG-PON use the same 1270 nm upstream and 1577 nm downstream wavelengths, while GPON uses the 1310 nm upstream and 1490 nm downstream wavelengths. The three-rate Combo PON optical module implements the transmission of four wavelengths over a single fiber.

Combo PON Solution

1. Smooth Evolution: Combo PON technology realizes two-in-one GPON and XG(S)-PON ports, and three-in-one GPON, XG(S)-PON and WDM1r optical modules, realizing smooth evolution of GPON to 10G GPON and gigabit speedup.
2. Innovative Technology: Combo PON solution with uplink WDM and dual channels. High uplink bandwidth, simpler planning, and management; standardization of technology and optical modules, better compatibility, and interoperability.
4. Smooth Engineering: Only OLT equipment transformation, "0" change in server room space, ODN, optical power budget, etc.
5.Smooth Operation and Maintenance: Simple OSS docking, no change in the opening process, fast cut over, and online.
6. Resource Revitalization: The original GPON board can be recycled to maximize investment value.

Advantages of Combo PON
The Combo PON solution only needs to replace the line card to achieve a smooth upgrade of high-bandwidth services. It has the following advantages:


● Save space in the equipment room and simplify operation and maintenance.
● Reduce initial investment and smooth investment income
● Does not affect the existing network GPON service, smooth network upgrade
● Reduce the cost of central office deployment
● Achieves a smooth upgrade from GPON to 10G GPON, convenient gigabit speed up, improves the quality of optical broadband, ensures business competitiveness, and maximizes value.

Application of Combo PON
Combo PON is used in 4K TV, 3D games, HD video, AR\VR, clouding networks, FTTx networks, 5G networks, etc.

Future Evolution and Prospect of Combo PON
It is widely believed in the industry that networks will evolve towards ultra-high bandwidth, ultra-low latency, and massive connection. How to simply and efficiently upgrade system capacity and reduce transmission latency has become a hot research topic in the PON arena. The next-generation Combo PON technologies following 10G PON will develop in two directions: Increase the single-wavelength rate to meet the deployment requirements of future wired broadband and use multi-wavelength superposition to meet the deployment requirements such as 5G front-haul. 
 
Conclusion
Combo PON helps operators rapidly and flexibly provision high-bandwidth services, simplify network construction, and reduce deployment costs.
