A Terabit network processor by 2015?

Given that 100 Gigabit merchant silicon network processors will appear this year only, it sounds premature to discuss Terabit devices. But Alcatel-Lucent's latest core router family uses the 400 Gigabit FP3 packet-processing chipset, and one Terabit is the next obvious development.

OpenFlow extends its control to the optical layer

OpenFlow may be causing an industry stir as system vendors such as ADVA Optical Networking extend the protocol's reach to the optical layer, but analysts warn that it will take years before the technology benefits operators' revenues.

 

"We see OpenFlow as an additional solution to tackle the problem of network control"

Jörg-Peter Elbers, ADVA Optical Networking

OTN processors from the core to the network edge

The latest silicon design announcements from PMC and AppliedMicro reflect the ongoing network evolution of the Optical Transport Network (OTN) protocol.


"There is a clear march from carriers, led in particular by China, to adopt OTN in the metro"

Scott Wakelin, PMC

OneChip Photonics targets the data centre with its PICs

OneChip Photonics is developing integrated optical components for the IEEE 40GBASE-LR4 and 100GBASE-LR4 interface standards.

The company believes its photonic integrated circuits (PICs) will more than halve the cost of the 40 and 100 Gigabit 10km-reach interfaces, enough for LR4 to cost-competitively address shorter reach applications in the data centre.

 

"I think we can cut the price [of LR4 modules] by half or better”

Andy Weirich, OneChip Photonics

Optical transmission's era of rapid capacity growth

Kim Roberts, senior director coherent systems at Ciena, moves from theory to practice with a discussion of practical optical transmission systems supporting 100Gbps, and in future, 400 Gigabit and 1 Terabit line rates. This discussion is based on a talk Roberts gave at the Layer123's Terabit Optical and Data Networking conference held in Cannes recently. 

Part 2: Commercial systems

 

The industry is experiencing a period of rapid growth in optical transmission capacity. The years 1995 till 2006 were marked by a gradual increase in system capacity with the move to 10 Gigabit-per-second (Gbps) wavelengths.  But the pace picked up with the advent of first 40Gbps direct detection and then coherent transmission, as shown by the red curve in the chart.
