On July 18th, 2016, Lightwave Online reported that ZTE USA had successfully transmitted a single-carrier 800-Gbps signal over a long-haul fiber optic link. The company says it used electrical time-division multiplexing (ETDM)-based 16QAM to send a 120-Gbaud WDM signal 1,200 km of TeraWave fiber. The signal benefited from the application of optical pre-emphasis on the transmitter side and maximum likelihood sequence estimation (MLSE) on the receiver side.

ZTE says it transmitted 12 WDM channels on a 150-GHz grid. Each channel transmitted a total of 960 Gbps, 800 Gbps of data signals plus 20% forward error correction (FEC) emulated overhead bits. The 1,200-km link comprised 100-km spans of the “base” version of TeraWave fiber that features a loss of 0.184 dB/km and an effective area of 125 μm2, according to a source at OFS. The transmission achieved spectral efficiency of 5.33 bps/Hz.

Liberty Port has partnered with ZTE throughout the world in the deployment of WDM Technology and Solutions for both Internet Service Providers and Data Center customers. Due to ZTE‘s continuous dedication to the advancement of WDM Technologies, Liberty Port has been able to offer customers a variety of high quality solutions such as the ZXMP M820, ZXMP M721, ZXMP M920, and the ZXMP M600.
