Oclaro optimises InP ultra-fast switching lasers for Huawei

A collaboration between the two firms sees the performance of Oclaro's indium phosphide tuneable laser rocket for Huawei's future optical network

Oclaro has worked closely with Huawei to drive the development of Petabit Photonic Cross-Connect (PPXC) technology that can realise Petabit OTN switching in an all optical way with fine granularity.

As part of the collaboration, Oclaro optimised its InP tuneable laser technology to deliver prototypes of ultra-fast switching lasers that enabled Huawei to develop the PPXC system.

Huawei will be hosting a live demo of this PPXC system in a private suite at this week's OFC/NFOEC show in Los Angeles, California.

Agile and ultra-large capacity OTN switching is a promising technology for future optical networks. A key component of this is fast tuneable laser technology, which Oclaro has successfully developed and optimised to meet Huawei's optical networking needs for the future.

"Fast tuneable lasers have great potential in Huawei's future optical network architectures and we are excited to see that Oclaro has successfully developed this enabling laser system with nanosecond tuning time," says Changtian Cai, President of Huawei Transport Network.

"We believe that all-optical cross connect technology will give an unparalleled advantage to ultra large capacity OTN switch clusters of future transport backbone networks, large data centres and other application scenarios and by partnering with a proven technology and manufacturing leader such as Oclaro, we can bring higher performance network equipment into our customers."

"As a leading provider of tuneable lasers, Oclaro has a deep understanding of the key technologies that are critical to delivering next generation optical networks," adds Yves LeMaitre, Chief Commercial Officer for Oclaro. "By working with Huawei in these early stages of development, we can play a key role in driving the advancement of the core optical network and delivering the performance and scalability that service providers need for many years to come."

The Oclaro fast tuneable laser utilises InP based technologies, which enable compact InP modulators and high performance widely tuneable lasers. To date, Oclaro has shipped over 300,000 tuneable lasers into the field as part of its iTLA, TTA, tuneable XFP, and SFF tuneable transponder products. More recently, to support the need for higher levels of integration, Oclaro has successfully demonstrated that fully monolithic PIC's (Photonic Integrated Circuits) using InP can be used to deliver higher performance at lower cost.
