Nec optical cable equipment

NEC provides advanced optical cable equipment, including high-performance optical transceivers, submarine cables, and transponders for long-distance, high-capacity data transmission.

Optical Transceivers

NEC has over 30 years of experience in developing and manufacturing optical transceivers, which are critical for converting electrical signals into optical signals and vice versa. These devices are designed for high reliability and performance, supporting global markets including North America, Europe, and Japan . NEC's transceivers are used in both terrestrial and submarine networks to ensure efficient and stable optical communication.

Submarine Cable Systems

NEC is a leading provider of optical submarine cable systems, with decades of experience laying over 400,000 kilometers of cable worldwide . Notable projects include the Southeast Asia-Japan Cable 2 (SJC2), a 10,500 km high-capacity cable connecting Singapore, Hong Kong, and Japan, capable of transmitting over 126 terabits per second using wavelength division multiplexing technology . NEC also qualifies subsea repeaters and optical cables with up to 20 fiber pairs, enabling the highest traffic capacity while optimizing cost per bit .

High-Capacity Transmission Technologies

NEC has achieved significant milestones in long-distance optical transmission, including a field trial delivering 800 Gbps over 2,100 km using the XF3200 transponder . The company is also advancing multicore fiber technology, such as 12-core coupled fibers, which allow multiple optical signals to be transmitted simultaneously in a single fiber, increasing capacity without enlarging the fiber diameter . These innovations are critical for supporting growing global data traffic, 5G networks, and future 6G infrastructure.

Applications and Advantages

NEC's optical cable equipment is used in:

• International and regional submarine networks for high-speed internet and cloud services.
• Terrestrial core networks to support large-scale data centers and AI-driven applications.
• Next-generation optical infrastructure with low latency, high reliability, and scalable capacity. By integrating optical transceivers, submarine cables, and advanced transponders, NEC provides a comprehensive solution for high-capacity, long-distance optical communication, supporting both current and future network demands .
