Chinese submarine communications specialist HMN Tech has announced the completion of a 32-fibre pair optical amplifier/repeater prototype considerable, following what it says was considerable research and development. The company says the next-generation submarine product will achieve capacity transmission at a petabit-level, aligning with the rising demand for increased fibre count on SDM systems and the on-going requirements for greater SLTE transmission capabilities.

HMN Tech’s says its extensive R&D activities and laboratory testing has optimised the device’s electronic performance by improving circuit design and employing a pump-sharing structure to reduce voltage drop and power consumption. Focus on both mechanical and structural design enhancements coupled with optical-electric component integration has doubled the fibre count from HMN Tech’s existing 16 fibre pair repeater products and systems that are already in commercial service.

The company says this next-generation system design enables a broad range of applications. It supports direct, long-distance transoceanic connectivity, with high reliability, superior capacity and low latency information networks. It also meets the demands of various end-users for network flexibility and fibre-pair independence.

“After recently delivering the world’s first 16 fibre pair repeater system, HMN Tech is proud to launch the next generation 32 fibre pair submarine repeater prototype. It breaks all existing industry limitations will provide a robust, qualified alternative for our customers,” stated Ma Yanfeng, executive vice president. “HMN Tech strives to provide innovative submersible products and solutions to further unlock new business opportunities and commercial applications ultimately achieving our customers’ business success.”

Commercial release of a fully qualified product is targeted for 2022.
