The launch of the domestic "Double Gigabit" action plan and the 14th Five-Year Plan for the digital economy has driven the number of 10GPON and above ports to grow from over 5 million at the end of 2021 to 12 million by the end of 2025; the number of gigabit broadband users has also expanded nearly tenfold to 60 million. In the overseas market, North America's AT&T plans to double its fiber coverage by the end of 2025. Institutions predict that as more operators utilize PON to support their access network strategies, the global PON equipment port will maintain a compound growth rate of 12.3%, and the penetration rate of 10GPON, 25G PON, and 50G PON PON port solutions will reach 50%. The future market space for PON optical modules is vast.
Since 2020, Shanghai Beiling has launched a series of SoC products dedicated to optical modules, which have been widely recognized by mainstream module manufacturers and have been applied on a large scale in 5G fronthaul and data communication 25Gbps/100Gbps module products in the telecommunications market. For access network PON OLT and ONU optical module products, Shanghai Beiling offers a variety of dedicated series product models, providing the most competitive solution options for customers' different PON technology solutions.
Features of the dedicated SoC product series for optical modules:
Two I2C modules that support multi-address mode for slave devices, flexible configuration, high speed and high reliability; compatible with different mainstream device manufacturers.
Internal digital modules (such as I2C, PWM) can be mapped to any IO port, supporting flexible port function allocation.
The PLU module with 4 built-in units can achieve relatively complex logical functions.
The IO supports 5V tolerance, meeting the electrical characteristic requirements of the module for the port.
It provides up to 22 channels of 12-bit ADC and 2/4 channels of 12-bit DAC.
It is equipped with a factory-calibrated high-precision temperature sensor.
Supports internal LDO 1.8V/2.4V output.
It offers small-sized packages such as QFN20 (3mm x 3mm), QFN24 (3mm x 3mm), and QFN32 (4mm x 4mm).
