Elenion's coherent and fibre-to-the-server plans

  • Elenion’s coherent chip - an integrated modulator-receiver assembly - is now generally available. 
  • The company has a silicon photonics design library that includes over 1,000 elements. 
  • Elenion is also developing an optical engine for client-side interfaces.

Elenion Technologies has given an update on its activities and strategy after announcing itself eight months ago. The silicon photonics-based specialist is backed by private equity firm, Marlin Equity Partners, which also owns systems vendor, Coriant. Elenion had already been active for two and a half years and shipping product when it emerged from its state of secrecy last December

Larry SchwerinElenion has since announced it is selling its telecom product, a coherent transceiver PIC, to Coriant and now other companies.

It has also progressed its optical engine design for the data centre that will soon be a product. Elenion has been working with Ethernet switch chip maker, Cavium, and data centre player, Microsoft, as part of its datacom work.

“We have moved forward,” says Larry Schwerin, the CEO of Elenion.

Coriant's 134 terabit data centre interconnect platform

Coriant is the latest optical networking equipment maker to unveil a data centre interconnect product. The company claims its Groove G30 platform is the industry’s highest capacity, most power efficient design. 

“We have several customers that have either purpose-built data centre interconnect networks or have data centre interconnect as a key application riding on top of their metro or long-haul networks,” says Jean-Charles Fahmyvice president of cloud and data centre at Coriant.

Each card in the platform is one rack unit (1RU) high and has a total capacity of 3.2 terabit-per-second, while the full G30 rack supports 42 such cards for a total platform capacity of 134 terabits. The G30's power consumption equates to 0.45W-per-gigabit.

The card supports up to 1.6 terabit line-side capacity and up to 1.6 terabit of client side interfaces. The card can hold eight silicon photonics-based CFP2-ACO (analogue coherent optics) line-side pluggables. For the client-side optics, 16, 100 gigabit QSFP28 modules can be used or 20 QSFP+ modules that support 40 or 4x10 gigabit rates.
