Upgrading Existing Submarine Cable Systems

Huawei Marine's flexible upgrading solutions can be applied to  all network conditions and bring the maximum benefit to its customers. In addition, Huawei Marine's excellent SLTE can ultimately expand system capacity in the original system to meet the customer's requirement of system bandwidth. Regardless of the original suppliers of the existing system, Huawei Marine' solutions can be used for any application scenario. 


We provide:

Full-SLTE replacement upgrade

Full SLTE replacement upgrade completely changes the SLTEs in Landing Stations, without affecting any wet plant equipment or PFEs. The higher bit-rate, and narrower channel spacing of the new SLTE will increase the capacity of the original system.

Dark fibre upgrade

Dark fibre upgrades expand system capacity by adding new SLTE for the unlighted fibres of the existing system. This solution will not affect wet plant equipment or PFEs. Additionally, it will not affect traffic in lit fibres.

Overlay wavelength upgrade

Overlay (Hybrid) wavelength upgrades add new SLTEs to the system to expand bandwidth capacity. In contrast to full SLTE replacement, this solution keeps the old SLTE and adds new wavelengths to existing traffic through couplers.
