Tektronix buys optical transmission analysis firm

Tektronix Inc. buys optical transmission test equipment provider, Optametra LLC that pioneered coherent light testing for use in R&D and manufacturing. The details of the transaction were not disclosed.

Optametra was founded in 2007 and launched its 40G Coherent Lightwave Signal Analyser in March 2009, followed up with a 100G later that same year.

Coherent lightwave signal analysis enables understanding and optimisation of optical networks using advanced modulation schemes to achieve transmission rates of 100G and beyond.

"The emergence of coherent optical standards is creating a technology shift in the communications market and new testing challenges are emerging," says Amir Aghdaei, president of Tektronix.

Optametra banks on the compelling value proposition of complex (amplitude and phase) optical modulation that allows carriers to smoothly grow data rates without pulling new fibre. The company claims that carriers such as Verizon and network equipment manufacturers such as Alcatel-Lucent have demonstrated 112Gbps transmission in an otherwise 10Gbps channel using complex modulation. By comparison, conventional modulation leaves 90 per cent of the fibre capacity unused.

Recently, Optometra added 3D analysis and visualisation capabilities to view text waveform constellations in three dimensions instead of two, thereby enhancing the utility of coherent signal analysis on oscilloscopes. "With Optametra's focus on coherent, we continue to provide industry-leading relevant signal analysis capabilities, now including 3D constellation display", says Daniel van der Weide, Optametra's VP of Engineering.
