Grating-based components supplier TeraXion has announced delivery of its first tunable chromatic dispersion compensators to three major system manufacturers. The TH-TDC tunable dispersion compensators will be evaluated for integration in 40-Gbit/sec systems. According to the company, the compensators offer accurate dispersion levels, very low group delay ripples, and low power consumption.
"Our customers are actively involved in developing next-generation 40-Gbit/sec systems and it is very important for us to be a partner in their design phase," says Etienne Gagnon, vice president, sales and marketing.
TeraXion developed the TH-TDC by combining its grating-based components with its patent pending, proprietary tunable technology platform.
Forty-Gbit/sec systems require 16 times more accuracy in dispersion management than those operating at 10 Gbits/sec, claims the company. Climatic variations as well as component aging can cause chromatic dispersion levels to exceed system tolerances for proper transmission. Designed to be placed before the receivers, TeraXion's TH-TDC counteracts this undesired effect by dynamically adjusting small dispersion variations that can bring down a 40-Gbit/sec link.
