II-VI shrinks an optical line system into an OSFP module

II-VI has developed an optical line system that fits inside a pluggable module. 

The advent of coherent pluggable modules implementing the 400ZR standard allows switches and routers to be linked across separate data centres. Now, with a pluggable optical line system, a dedicated line-system platform is no longer needed to send the 400ZR signals over a fibre. 

Sanjai ParthasarathiIn turn, the network operating system on the switch manages the optical line system directly such that a separate optical management software layer is no longer needed.

“We have shrunk an entire pizza-box line system into a small pluggable,” says Sanjai Parthasarathi, chief marketing officer at II-VI.

Indeed, one customer refers to the II-VI pluggable product - dubbed the OSFP-LS - as a ‘zero-rack-unit’ platform.

Infinera’s ICE6 sends 800 gigabits over a 950km link

Infinera has demonstrated the coherent transmission of an 800-gigabit signal across a 950km span of an operational network.

Robert ShoreInfinera used its Infinite Capacity Engine 6 (ICE6), comprising an indium-phosphide photonic integrated circuit (PIC) and its FlexCoherent 6 coherent digital signal processor (DSP). 

The ICE6 supports 1.6 terabits of traffic: two channels, each supporting up to 800-gigabit of data. 

The trial, conducted over an unnamed operator’s network in North America, sent the 800-gigabit signal as an alien wavelength over a third-party line-system carrying live traffic.

“We have proved not only the state of our 800-gigabit with ICE6 but also the distances it can achieve,” says Robert Shore, senior vice president of marketing at Infinera.

ECOC 2019 industry reflections II

Gazettabyte requested the thoughts of industry figures after attending the ECOC show, held in Dublin. In particular, what developments and trends they noted, what they learned and what, if anything, surprised them. Input from II-VI, Ciena, Fujitsu Optical Components and Acacia Communications. The second and final part. 

Sanjai Parthasarathi, chief marketing officer at II-VI 

One new theme at ECOC is the demand for lower-cost 100-gigabit coherent transceivers for deployment in optical access for wireless access and fibre-deep cable TV. Such demand would significantly expand the market.

It was noteworthy at the show how 5G has become a significant factor influencing the wireless access market, with the potential for wide deployment of dense wavelength-division multiplexing (DWDM) technology with wavelength switching and tuning functions, not only in traditional network architectures but interesting new ones too.

Interview: Finisar’s CEO reflects on a notable year

Michael Hurlston has had an eventful 2018. 

The year started with him replacing Finisar’s veteran CEO, Jerry Rawls, and it is now ending with Finisar being acquired by the firm II-VI for $3.2 billion.

Michael Hurlston

Finisar is Hurlston’s first experience in the optical component industry, having spent his career in semiconductors. One year in and he already has strong views about the industry and its direction.

“We have seen in the semiconductor industry a period of massive consolidation in the last three to four years,” says Hurlston, in his first interview sinced the deal was announced. “I think it is not that different in optics: scales matters.”    

Hurlston says that, right from the start, he recognised the need to drive industry consolidation. “We had started thinking about that fairly deeply at the time the Lumentum-Oclaro acquisition was announced and that gave us more impetus to look at this,” says Hurlston. The result was revealed in November with the announced acquisition of Finisar by II-VI.
