Submarine Line Terminal Equipment (SLTE)

Submarine cables are the backbone of global connectivity. SLTE is the cornerstone of the data highway that transport vast amounts of data on these cables.

Recognized as the platform with high integration level in the industry

Huawei Marine's SLTE products, the OSN 8800 and OSN 9800, leverage Huawei's industry leading WDM technology to deliver reliable, high performance, large capacity optical transmission across the vast reaches of submarine cable networks.
