San Jose, CA--Oclaro (NASDAQ: OCLR) and Huawei (Shenzhen, China) announced an agreement to develop Petabit Photonic Cross-Connect (PPXC) technology. As part of the collaboration, Oclaro has optimized its indium phosphide (InP) tunable laser technology to deliver prototypes of ultra-fast switching lasers that enabled Huawei to develop the PPXC system. Huawei will be showing a live demo of this PPXC system in a private suite at this week's OFC/NFOEC show in Los Angeles, CA.

"Fast tunable 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," said 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 [optical transport network] switch clusters of future transport backbone networks, large data centers, and other application scenarios."

To date, Oclaro has shipped over 300,000 tunable lasers into the field as part of its iTLA, TTA, tunable XFP, and SFF tunable transponder products. More recently, the company has demonstrated that fully monolithic photonic integrated circuits (PICs) in InP.
