Infinera speeds PIC development

摘要

Infinera, widely credited with boosting monolithic photonic integration from lab curiosity to commercial reality, is thinking along the same lines as the component and subsystem suppliers quoted in this article when it comes to supporting speeds of 40 and 100 Gbits/ sec. Not surprisingly, however, they're also thinking more aggressively. The heart of the systems company's DTN platforms comprises photonic integrated circuits (PICs), active and passive monolithically integrated devices that combine 60 discrete devices into two chips-50 devices in the case of the transmit PIC. The devices currently support a total of 100 Gbits/sec per chip (10 channels of 10 Gbits/sec each) and have surpassed 100 million hours in the field without failure, the company recently announced.
