The ZTE GFXL is a 16-port XG-PON OLT interface board applicable to ZTE ZXA10 C600/C650/C680 OLTs, which provides 16-port XG-PON access, supports a maximum split ratio of 1:256, and features Optical Line Supervision (OLS), the optical module Auto Laser Shutdown (ALS) function as well as hot-swappable capability; meanwhile, the ZTE GFTL is a 16-port XGS-PON OLT interface board compatible with N1/N2a modules that can also be applied to the same ZXA10 C600/C650/C680 OLT models, characterized by a maximum optical split ratio of 1:256, along with support for optical power monitoring, the optical module ALS function and hot swapping to ensure efficient and reliable network operation and maintenance.
1. Residential Broadband Expansion in Italy
An Italian telecom deployed ZTE GFXL 16-port XG-PON boards on ZXA10 C650 OLTs for broadband expansion in Milan’s suburban areas. With a 1:256 split ratio, each board efficiently served 4,000+ households, delivering 10Gbps downstream and 2.5Gbps upstream speeds—ideal for 4K streaming and cloud services. OLS enabled real-time line fault detection, ALS protected maintenance teams, and hot-swappable design allowed non-disruptive upgrades, aligning with Italy’s goal of universal gigabit coverage.
2. Campus Network Upgrade in South Korea
A top South Korean university adopted ZTE GFXL boards on ZXA10 C680 OLTs to upgrade its campus network. The 16-port XG-PON access supported thousands of students and staff across classrooms, labs, and dormitories, with the 1:256 split ratio optimizing fiber resource utilization. Backward compatibility with existing GPON infrastructure reduced costs, while OLS and ALS ensured stable connectivity for online classes and research data transfers. Hot-swappable capability minimized downtime during peak academic periods
