FAQS

Why should I choose Global Wavelength?

The massive amounts of data transmitted today are driving unprecedented bandwidth demands on service provider and enterprise networks. Traditional data transmission technologies can’t handle the volumes of information that need to be moved quickly between locations. China Telecom’s Global Wavelength Services are designed to deliver high capacities of data over our ultra-low latency connections.

Aren’t wavelength services expensive?

China Telecom’s Global Wavelength Services are ideally suited for customers who require dedicated broadband transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. Our solution actually reduces upfront and long-term costs.

Are China Telecom’s Global Wavelength Services the right choice for my organization?

China Telecom’s Global Wavelength Services are ideal for ISPs, carriers, hyperscale / web scale companies, and multinational enterprises with high data transmission requirements. Our wavelength services are also appropriate for applications such as data center interconnections and inter-cloud connections, business continuity and disaster recovery, Internet of Things (IoT) networks, multimedia high-resolution 4K and 8k video streaming, online education networks, fiber channel / storage networking, e-sports / gaming use-cases, as well as AI.

What are China Telecom’s Future Plans for Optical Networking?

China Telecom is actively building out its “all-optical backbone network 2.0” plan which is currently the world’s largest in scale and coverage, with a total length of 220,000 km, 470 ROADM nodes, 5,039 lines of 100G and total capacity of 590Tbit/s.  All areas of the network will gradually move towards openness, with more interface standardization, software and hardware decoupling, and hardware white box. China Telecom’s goal for the all-optical network is to reduce restoration time from the current time of a few minutes to ten seconds or less, and will take advantage of AI to increase network efficiency.
