Teraxion embraces silicon photonics for its products

Teraxion has become a silicon photonics player with the launch of its compact 40 and 100 Gigabit coherent receivers.

The Canadian optical component company has long been known for its fibre Bragg gratings and tunable dispersion compensation products. But for the last three years it has been developing expertise in silicon photonics and at the recent European Conference on Optical Communications (ECOC) exhibition it announced its first products based on the technology.

 

"You don't have this [fabless] model for indium phosphide or silica, while an ecosystem is developing around silicon photonics"

Martin Guy, Teraxion

AppliedMicro samples 100Gbps CMOS multiplexer

AppliedMicro has announced the first CMOS merchant multiplexer chip for 100Gbps coherent optical transmission. The S28032 device supports dual polarisation, quadrature phase-shift keying (DP-QPSK) and has a power consumption of 4W, half that of current multiplexer chip designs implemented in BiCMOS.

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"

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.

2012: The year of 100 Gigabit transponders

Oclaro has detailed its 100 Gigabit coherent optical module that will be available from the second quarter of 2012. The MI 8000XM, a 5x7-inch 100 Gigabit-per-second (Gbps) transponder, uses NTT Electronics' (NEL) analogue-to-digital converter/ digital signal processor (DSP) ASIC at the receiver that compensates for transmission impairments.

 

“The world is moving to coherent, there is no question about that”

100 Gigabit: An operator view

Gazettabyte spoke with BT, Level 3 Communications and Verizon about their 100 Gigabit optical transmission plans and the challenges they see regarding the technology.

 

Briefing: 100 Gigabit

Part 1: Operators 

Operators will use 100 Gigabit-per-second (Gbps) coherent technology for their next-generation core networks. For metro, operators favour coherent and have differing views regarding the alternative, 100Gbps direct-detection schemes. All the operators agree that the 100Gbps interfaces - line-side and client-side - must become cheaper before 100Gbps technology is more widely deployed.

 

"It is clear that you absolutely need 100 Gig in large parts of the network"

Steve Gringeri, Verizon

100 Gigabit: The Coming Metro Opportunity

Gazettabyte has published a Position Paper on the coming 100 Gigabit metro opportunity. (Click here to download a copy.) There has been several announcements in recent weeks from system and component vendors addressing 100 Gigabit metro networks.

 

The 19-page report looks at the status of the 100 Gigabit market, the drivers for 100 Gigabit deployment, the technology options and their merits. The paper then states how 100 Gigabit technologies such as direct-detection point-to-point, direct-detection WDM and coherent will fare in the metro.
