Oclaro’s 400-gigabit plans

Adam Carter, Oclaro’s chief commercial officer, discusses the company’s 400-gigabit and higher-speed coherent optical transmission plans and the 400-gigabit client-side pluggable opportunity.    

Oclaro showcased its first coherent module that uses Ciena’s WaveLogic Ai digital signal processor at the ECOC show held recently in Gothenburg.

Adam CarterOclaro is one of three optical module makers, the others being Lumentum and NeoPhotonics, that signed an agreement with Ciena earlier this year to use the system vendor’s DSP technology and know-how to bring coherent modules to market. The first product resulting from the collaboration is a 5x7-inch board-mounted module that supports 400-gigabits on a single-wavelength.   

The first WaveLogic Ai-based modules are already being tested at several of Oclaro’s customers’ labs. “They [the module samples] are very preliminary,” says Adam Carter, the chief commercial officer at Oclaro. “The really important timeframe is when we get towards the new year because then we will have beta samples.”

Merits and challenges of optical transmission at 64 Gbaud 

u2t Photonics announced recently a balanced detector that supports 64Gbaud. This promises coherent transmission systems with double the data rate. But even if the remaining components - the modulator and DSP-ASIC capable of operating at 64Gbaud - were available, would such an approach make sense?

Gazettabyte asked system vendors Transmode and Ciena for their views.

u2t Photonics pushes balanced detectors to 70GHz

  • u2t's 70GHz balanced detector supports 64Gbaud for test and measurement and R&D
  • The company's gallium arsenide modulator and next-generation receiver will enable 100 Gigabit long-haul in a CFP2

 

"The performance [of gallium arsenide] is very similar to the lithium niobate modulator"

Jens Fiedler,  u2t Photonics
