Huawei to deploy 100G network for Unitel in Africa

Huawei Technologies Co. Ltd. plans to deploy what it claims is Africa's first 100G DWDM network for the mobile carrier Unitel. The equipment maker says the new network marks the start of commercial applications of 100G networks on the African continent.

Huawei Technologies Co. Ltd. plans to deploy what it claims is Africa's first 100G DWDM network for the mobile carrier Unitel. The equipment maker says the new network marks the start of commercial applications of 100G networks on the African continent.

Using such optical transport technology as coherent transmission and Automatically Switched Optical Network (ASON), this network will offer Unitel a future-ready intelligent and “infinite bandwidth cloud,” according to Huawei.

Unitel has the largest and most advanced mobile broadband network in Angola, but faces challenges to remain competitive, Huawei asserts. These challenges include greater bandwidth requirements as new services, such as HSPA+, LTE, and FTTx, continue to grow, and accidental damage to fiber-optic cables, which frequently occurs due to fast-paced construction in urban areas.

Huawei says its 100G ASON equipment offers an answer to these challenges through the combination of multiple technologies. First, the coherent detection technology achieves a future-proof capacity of up to 8 Tbps per fiber over an ultra-long reach. Second, Huawei's ASON technology supports resilient protection against multiple fiber cuts and thus enhances network reliability. This ASON technology also enables operable and management bandwidths by offering a great variety of service classes. Third, Huawei-developed 100G Optical Transport Network (OTN) technology drastically improves network efficiency and flexibility, by virtue of its support for multi-service access, multiplexing, and cross-connections.

Jack Wang, president of Huawei's transport product line, said, "Huawei is about to use cutting-edge 100G technology to link the African continent together, and to enrich people's lives in Africa by offering faster and more efficient communications."

The Chinese vendor says its 100G networks serve more than 40 carriers in over 30 countries and span over 50,000 km.
