ZTE deploys low-latency PON for China Mobile

ZTE today announced that its low-latency PON solution has been applied by the Suzhou branch of China Mobile to indoor coverage scenarios and completed a validation on the operator’s live network in Suzhou Industrial Park.

The validation demonstrates that the low-latency PON has reduced latency by 60 percent on average compared with regular PON. The solution allows both mobile and home broadband services to be connected via one fiber without interfering with each other during concurrent transmission.

ZTE’s low-latency PON solution is based on ZTE’s TITAN OLT platform and innovative low-latency ONU product. The solution employs latency reduction technologies, such as short-period Dynamic Bandwidth Allocation (DBA), Fixed Bandwidth Allocation (FBA), quiet windows, and intensive bursts, to shrink the maximum lag to one-sixth of the previous levels. Therefore, the PON system can offer not only high bandwidth but also lower latency, to meet the requirements of diverse scenarios, including 4K/8K/VR/gaming, fixed-mobile dual-gigabit broadband, industrial internet, and dedicated enterprise line.

Moving forward, ZTE will optimize the low-latency PON solution and further cooperate with China Mobile in the field of 5G+FTTH/O dual-gigabit access.
