CMOS transmitter ICs achieve line rates to 31.8 Gbps/channel for 100G networks
Applied Micro Circuits announced what it asserts is the world’s fastest CMOS transmitter ICs for Dense Wavelength Division Multiplexing line-side applications, which support power-efficient, cost-effective deployments in 100-Gigabit per second optical metro, regional and long-haul networks. With line rates up to 31.8 Gbps per channel, the S28032 DQPSK Mux chips are positioned to pave the way for wide-scale deployment in 100G DWDM Optical Transport Networks (OTN) as operators increasingly seek higher bandwidth solutions and greater network density. CMOS ICs provide a scalable high-volume, low-power solution for ramping 100G deployments. The IC provides a flexible interface to connect either FPGAs or ASICS running hard or soft-decision FEC (Forward-Error Correction) on a 10 or 20-lane SFI-S bus to optical drivers for PM-QPSK and other DWDM optical systems. The S28032 supports line rates from 2 7Gbps through 31.8 Gbps for applications with 7, 15, or 20 percent FEC overhead. The company reportsEarly access partners, who represent significant market share, are passing traffic error-free in the lab in preparation for field trials.
