Huawei's 400G Helps Transworld Enhance Internet Quality and Capacity in Pakistan

Background

Transworld, founded in 2006, stands as a leading connectivity provider in Pakistan. It supplies internet bandwidth to major mobile operators, ISPs, corporate enterprises, and hundreds of SMEs. Leveraging its extensive fiber optic network, Transworld seamlessly connects Pakistan to the digital world.

The company owns TW1, a 1,300 km submarine cable system connecting Pakistan with the UAE and Oman. It is also a consortium member of several cable networks, including SEA-ME-WE 5 (20,000 km) and the upcoming SEA-ME-WE 6 (21,700 km), and serves as a landing partner for 2Africa Cable. Together, these cable systems provide Pakistan with robust connectivity to the Asia-Pacific, Middle East, and Europe.

Through direct connections with global content providers such as Google, Facebook, Netflix, Amazon, and Akamai, Transworld is deeply integrated into the international internet ecosystem. Its privately owned TW1 submarine cable and strong local presence enable it to deliver cost-effective solutions with unmatched service-level agreements (SLAs) to both local and international customers.

Challenges and Requirements

Transworld's backbone DWDM network, built in 2018, had reached full capacity, with no available wavelength resources. Rising traffic demand compelled the company to lease bandwidth from other operators, which increased the TCO and complicated operations and maintenance. To overcome these challenges, Transworld required the deployment of a next-generation, high-capacity DWDM backbone network designed to:

a. Support future growth and expansion.

b. Reduce dependency on leased bandwidth.

c. Simplify operations and maintenance.

d. Deliver high stability, speed, and performance to meet customer needs.

Huawei Solution: Future-Proof CDF Architecture with 400G Per Wavelength

Huawei provided a 400G solution designed for high bandwidth and low per-bit cost. Key features include:

a. A CDF network architecture enables smooth evolution to higher speeds (400G+ and beyond) while facilitating L-band expansion for enhanced capacity.

b. Delivering 400G per wavelength, each fiber achieves 25.6+ Tbps capacity—future-proofed to sustain growth for the next decade

c. A hybrid OTN and packet-based solution balances efficient bandwidth utilization while reducing the TCO.

d. ASON 2.0 technology delivers multi-level protection and ensures ultra-high reliability.

e. Huawei NCE platform enables unified management of DWDM, IP, and access networks.

Customer Benefits

a. High bandwidth: 400G resolved congestion issues.

b. Cost efficiency: "Pay-as-you-grow" RTU model reduced upfront costs.

c. High reliability: ASON 2.0 minimized switching time, delivering 99.999% network reliability.

d. Simplified operations: Unified NCE platform enabled efficient multi-domain management.
