India-heaquartered company Tejas Networks, which designs and manufactures high-performance wireline and wireless networking products, has announced the launch of TJ1600-D3, its next-generation, versatile WDM (wavelength division multiplexing) optical transport product.

The product, which is purpose-built to meet the surging demand for terabit-scale data centre interconnections worldwide, was unveiled by Shri Jyotiraditya Scindia, India’s Minister of Communications (MOC) at MWC26.

Powered by the latest digital signal processors and chipsets, the TJ1600-D3 is engineered for operators and enterprises demanding extreme capacity, carrier-grade reliability, and best-in-class energy efficiency. It supports a range of performance-optimised and power-optimised traffic sleds, with flexible line rates from 400G to 1.2T per wavelength and scaling up to 51.2 Tbps of shelf capacity.

Redundant controllers, fans and power modules combined with universal AC/DC power compatibility ensure that TJ1600-D3 delivers highly resilient services in an optimised 3-RU form factor.

Arnob Roy, Chief Operating Officer and Executive Director of Tejas Networks says: "Traffic patterns have shifted dramatically in recent years, with webscalers, carriers and cloud providers building out ever larger data centres, AI compute clusters and edge AI nodes. This has led to a fundamental reshaping of modern network architectures as our customers need compact, energy-efficient, and hyper-scalable products to reliably move massive volumes of data across these distributed facilities. TJ1600-D3 is an ideal, future-proof offering for this evolving connectivity requirement."
