ZTE a global provider of telecommunications equipment and network solutions, on Wednesday announced that it successfully achieved a signal transmission rate of 24Tb/s (24x1.3Tb/s) based on its wavelength-division multiplexing (WDM) technology. The transmission sets a new world record in optical networking and was published as a Post Deadline Paper (PDP) at the recent Opto-Electronics and Communications Conference (OECC) 2011 in Kaohsiung, Taiwan.
 
The successful transmission follows closely after another world record that ZTE broke after the transmission of single-channel 10Tb/s optical OFDM signals at Optical Fiber Communication Conference (OFC) in March 2011.

Transmission bit rate per channel at 1Tb/s is likely to become the industry mainstream after 100G (100Gb/s), having 10 times more capacity in terms of signal bandwidth. There have been only experimental reports about single-channel transmission rate at 1Tb/s before. However, ZTE has further accomplished 24Tb/s (24x1.3Tb/s) WDM signal transmission, which was the first WDM technology that achieved Terabit/s in the industry. 
 
 “Over the years, we have always been devoted to 100G and beyond-100G technology researches and committed ourselves to providing 100G solutions for IP network and optical transport networks. In the future, we will invest more resources to bring more of our research results to market with 100G global deployment,” said Mr. Fan Xiaobing, general manager of ZTE’s bearer network product line.
