[Shenzhen, China, June 19, 2017] Huawei announced a time division multiplexing (TDM) PON combo solution based on fiber to the home (FTTH) networks. Following the wavelength division multiplexing (WDM) PON combo solution released last year, the new solution further facilitates the smooth evolution of GPON to 10G GPON. It enables operators to align upgrade processes in EPON and GPON solutions, and reduce power attenuation caused by combiners. Moreover, this solution simplifies network upgrades, and smoothly evolve current networks to gigabit ones for high-end users and enterprises.

To implement GPON upgrades, operators need to deploy WDM1r combiners that combine both GPON and 10G GPON ports. The upgrade processes are complex. In addition, optical signals are attenuated due to the use of WDM1r combiners. To implement GPON upgrades by replacing boards, Huawei released the WDM PON combo solution in 2016. In this solution, a PON port integrates 3 components: GPON, 10G GPON, and WDM1r, having the same upgrade process as 10G EPON in terms of board replacement. This PON solution can be easily deployed, and does not require additional space or WDM1r devices.

Huawei launched the TDM PON combo solution (based on the WDM PON combo solution) in June 2017. This solution innovatively changes the upstream receiving mode of the WDM PON combo optical module into TDM receiving, allowing GPON and 10G PON optical signals to be transmitted in turn. This simplifies the combiner design, reduces implementation difficulties of PON combo optical modules, and allows higher power budgets. By using the TDM PON solution, vendors are able to realize mass production, implement small encapsulation, and integrate high-density port integration more easily.

Huawei is constantly innovating FTTH technologies. With a wealth of experience in PON and a deep understanding of customer demands, Huawei announces innovative PON combo solutions for the smooth evolution from GPON to 10G PON on after another at the dawn of gigabit ultra broadband (UBB) era. By deploying Huawei's solutions, operators can shield technology differences and unify upgrade processes, deploying gigabit networks rapidly and accelerating business success.

Huawei, a leading UBB solution provider, will continue to lead UBB development. Currently, Huawei's next-generation distributed smart OLT and 10G PON ONT have been put into large-scale commercial use by over 50 operators around the world. Huawei has also released the CloudFAN solution, which supports multi-service bearing over one fiber and maximizes the values of operators' access networks. By deploying this solution, operators are able to quickly provide home users with value-added services and provide enterprise customers with on-demand leased line services through cloud networks.

Digital transformation is bringing new development opportunities. Network construction and evolution is moving from a technology-driven to a business-driven approach. With business at the core of Huawei's All-Cloud Network, it will deliver agile, intelligent, efficient, and open networks that empower customers to achieve commercial success.
