ZTE Corp. is showing off what it asserts is the first multi-application 400-Gbps/1-Tbps DWDM prototype device at the 16th WDM & Next Generation Optical Networking Forum in Monaco this week.

The device can perform seven network applications via a variety of modulation formats, ZTE asserts. For example, the DWDM prototype offers a multi-subcarrier orthogonal frequency-division multiplexing (OFDM) 400G/1T approach for ultra-long-haul applications. It also can serve metro applications via a 16-QAM approach, or long-haul applications as a Nyquist WDM platform.

At 100 Gbps, ZTE the DWDM/Optical Transport Network (OTN) system supports C-band 80-wavelength applications via PM-QPSK and coherent detection and soft-decision forward error correction (FEC).

“ZTE is fully prepared to deploy solutions, products, and services for the large-scale commercial global rollout of 100G and ultra-100G,” said ZTE Bearer Network Product Line General Manager Chen Yufei.
