An insider's view on the merits of optical integration

One of the pleasures of attending the OFC show, held in Los Angeles last month, is the many conversations possible in one location. The downside is that too many are cut short due to the show's hectic schedule. One exception was a conversation with Valery Tolstikhin (pictured), held in a quiet room prior to the exhibition hall's opening.

Tolstikhin is president and CEO of Intengent, the Ottawa-based consultancy and custom design service provider, and an industry veteran of photonic integration. In 2005 he founded OneChip Photonics, a fabless maker of indium phosphide photonic integrated circuits for optical access

One important lesson he learned at OneChip was how the cost benefit of a photonic integrated circuit (PIC) can be eroded with a cheap optical sub-assembly made from discrete off-the-shelf components. When OneChip started, the selling price for GPON optics was around $100 a unit but this quickly came down to $6. "We needed sales in volumes and they never came close to meeting $6," says Tolstikhin.

Verizon prepares its next-gen PON request for proposal 

Verizon will publish its next-generation passive optical network (PON) requirements for equipment makers in the coming month.

Vincent O'Byrne

The NG-PON2 request for proposal (RFP) is being issued after the US operator completed a field test that showed a 40 gigabit NG-PON2 system working alongside Verizon’s existing GPON customer traffic.  

The field test involved installing a NG-PON2 optical line terminal (OLT) at a Verizon central office and linking it to a FiOS customer’s home 5 km away. A nearby business location was also included in the trial.

R&D: At home or abroad?

ECI Telecom chose to set up its latest R&D site in Israel. Gazettabyte met with Chaim Urbach, ECI’s head of global R&D operations, to discuss why it decided to locate its latest site in Israel, and how the company can compete with the leading telecom players that have considerably larger R&D teams and budgets.

BroadLight’s GPON ICs: from packets to apps

What is being announced?

BroadLight has announced its Lilac family of customer premise equipment (CPE) chips that support the Gigabit Passive Optical Network (GPON) standard.

The company claims its GPON devices with be the first to be implemented using a 40nm CMOS process. The advanced CMOS process coupled with architectural enhancements will double processing performance while improving five-fold the packet-processing capability.  The devices also come with a hardware abstraction layer that will help system vendors tailor their equipment.


"Traffic models and service models are not stable, and there are a lot of differences from carrier to carrier"
