100 Gigabit 'unstoppable'

A Q&A with Andrew Schmitt (@aschmitt), directing analyst for optical at Infonetics Research.


"40Gbps has even less value in the metro than in the core"

FPGA transceiver speed hikes bring optics to the fore 


Despite rapid increases in the transceiver speeds of field-programmable gate arrays (FPGA), the transition to optical has begun.

FPGA vendors Xilinx and Altera have increased their on-chip transceiver speeds four-fold since 2005, from 6.5Gbps to 28Gbps. But signal integrity issues and the rapid decline in reach associated with higher speed means optics is becoming a relevant option.

Is wireless becoming a valid alternative to fixed broadband?  

Are wireless technologies such as Long Term Evolution (LTE) and WiMAX2 closing the gap on fixed broadband? 

A recent blog by The Economist discussed how Long Term Evolution (LTE) is coming to the rescue of one of its US correspondents, located 5km from the DSL cabinet and struggling to get a decent broadband service. 

 

Peak rates are rarely achieved: the mobile user needs to be very close to a base station and a large spectrum allocation is needed.

The CFP4 optical module to enable Terabit blades

The next-generation CFP modules - the CFP2 and CFP4 - promise to double and double again the number of 100 Gigabit-per-second (Gbps) optical module interfaces on a blade.

Using the CFP4, up to 16, 100Gbps modules will fit on a blade, a total line rate of 1.6 Terabits-per-second (Tbps). With a goal of a 60W total module power budget per blade, that equates to 27Gbps/W. In comparison, the power-efficient SFP+ achieves 10Gbps/W.

Altera unveils its optical FPGA prototype

Altera has been showcasing a field-programmable gate array (FPGA) chip with optical interfaces. The 'optical FPGA' prototype makes use of parallel optical interfaces from Avago Technologies.

Combining the FPGA with optics extends the reach of the chip's transceivers to up to 100m. Such a device, once commercially available, will be used to connect high-speed electronics on a line card without requiring exotic printed circuit board (PCB) materials. An optical FPGA will also be used to link equipment such as Ethernet switches in the data centre.

"It is solving a problem the industry is going to face," says Craig Davis, product marketing manager at Altera. "As you go to faster bit-rate transceivers, the losses on the PCB become huge."
