Tue Dec 10 09:40:00 UTC 2024: ## NEC Launches New 100Gb/s Optical Transceiver for Cost-Effective, Long-Distance Data Transmission

**Tokyo, Japan –** NEC Corporation today announced the launch of its new 100G QSFP28 ZR4 BiDi optical transceiver, enabling 100Gb/s data transmission over a distance of up to 80km using a single fiber. This breakthrough addresses the growing demand for high-bandwidth, low-latency, and cost-effective data center interconnections fueled by the increasing adoption of AI and video streaming services.

Unlike traditional 100Gb/s transceivers requiring two fibers, the new ZR4 BiDi utilizes wavelength-division multiplexing (WDM) with a newly developed compact filter to achieve bidirectional communication on a single fiber. This innovation significantly reduces fiber procurement and rental costs. The transceiver incorporates a high-power laser transmitter and optical semiconductor amplifier receiver to ensure high-quality transmission over 80km, achieving a link budget of 30dB.

Furthermore, the ZR4 BiDi supports both Ethernet (103Gb/s) and OTU4 (111.8Gb/s) signal rates while maintaining a low power consumption of under 5.5W and utilizing a standard QSFP28 interface for easy integration into existing systems. Its direct-detection method, unlike coherent systems, contributes to lower latency and cost.

“This new transceiver represents a significant advancement in optical communication technology,” said [Insert Name and Title from NEC Press Release, if available]. “By combining single-fiber bidirectional transmission with direct-detection technology, we deliver a solution that optimizes cost, power consumption, and latency for data center interconnection.” NEC plans to continue developing and offering advanced optical transceivers incorporating cutting-edge technologies.
