New compact coherent module can be used in Padtec’s TMD400G-SD transponder and in routers, increasing transmission capacity over distances of thousands of kilometers.
Padtec, one of the world’s leading companies in optical communications systems, is launching a next-generation compact transceiver that enables operators and Internet Service Providers (ISPs) to increase their network capacity to 400 Gb/s over ultra-long distances. The new pluggable module, called QSFP-DD 400G Ultra Long Haul, is part of Padtec’s portfolio of products based on coherent modulation technology, which delivers greater reach, capacity, and energy efficiency.
Alexandre Piovesan, Padtec’s Director of Products, highlights that the pluggable combines three important factors: a compact interface, low power consumption, and high transmission capacity over distances of thousands of kilometers. He also emphasizes that the product is the result of a new generation of digital signal processors (DSPs), known as Gen120C, which enables operation at up to 120 Gbaud.
“The compact size allows the DSPs and other components to be integrated into a QSFP-DD optical transceiver operating at 400 Gb/s, with operating modes ranging from 65 Gbaud up to 120 Gbaud. In addition, the design of this pluggable was developed to meet the power consumption and thermal dissipation requirements of current-generation 400G transponders and routers,” explains Piovesan.
In addition to deployment in routers equipped with 400G ports, Padtec’s new coherent module can also be used in the company’s TMD400G-SD dual transponder, which is already prepared to support the new operating modes enabled by the pluggable. “For customers who already have this transponder installed, a firmware update is sufficient to use this new technology and enable a range of new applications, driven by higher transmission rates and increased signal robustness,” concludes the executive.
