PON player makes broader push into gigabit

Passive optical network (PON) semiconductor player iamba Networks Inc. is making a broader push into Gigabit PON with subsystems for the line- and network-termination sides of optical nets. Unlike competitors BroadLight Inc. and PMC-Sierra Inc., the Israeli company will emphasize board and packaged system designs more than individual chipsets.

Such a strategy is recognition of what most access OEMs want, said iamba CEO Moshe Nattiv. Telecom chip suppliers are being pushed to develop more complex reference designs, Nattiv said, but iamba is trying to offer more flexible design and software options to original design manufacturers and OEMs.

"We don't really want to sell high-volume chips," he said. "We offer a manufacturing license for a system design, application-layer software, and full electrical and mechanical design specs."

The core device on the network side is the iSN1000, a multicore processor based on a traffic-pump module, which can forward packets of any size at 1Gbps. The line-termination side is served by a dual-port iSL2402, supporting 64 optical network terminals per network, along with forward error correction and encryption. All three chips will debut first in FPGA format, and will be followed by full ASICs later in the year.

In most cases, the iSL2402 and iSL2404 will not be integrated with line-side systems, since OEMs tend to develop larger central-office and terminal aggregators based on their own design, though Nattiv said that iamba also has experience in system-level design in these realms.
