Microsemi's latest optical system linecard device is designed to address channel density issue with the uptake of 100G links.
"Growth of 100G is exceeding our most optimistic predictions and, in turn, significantly bolstering the optical transceiver end-market," said Andrew Schmitt, principal analyst for optical at market research firm Infonetics.
"The availability of components that increase the density of linecards is essential in order to support the rapid deployment of cost-effective 100G networks," said Schmitt.
To tackle the channel density issue, Microsemi has introduced a single-chip line card device for optical transport network (OTN) transport and switching.
The ZL30165 integrates four digital phased lock loops (DPLLs) capable of locking on to up to 10 inputs targeting muxponder applications that support multi-client transport on a single wavelength.
“This allows equipment makers to bridge the capacity bandwidth gap between existing 10G networks and 100G pipes that are now being deployed,” said Maamoun Seido, Microsemi vice president of Microsemi’s timing products group.According to Infonetics, total OTN revenue (OTN transport and switching equipment) was expected to be $7bn in 2012. This would represent 55% of all optical device spending.
It is predicted to grow at 13% per year to 2016. Then it would be 80% of all optical spending.
