PMC-Sierra quad-port EPON OLT SoCs target FTTH, mobile backhaul

September 22, 2011

PMC-Sierra, Inc. (Nasdaq:PMCS) has unveiled its latest EPON OLT system-on-chip (SoC) family. The quad-port PAS5400 devices integrate four 1-Gbps EPON MACs and feature integrated traffic management and packet processing, power-save modes that allow remote power down of customer premises equipment, in-band optical fiber testing, and support for mobile backhaul as well as fiber to the home (FTTH).

Broadcom targets EPON market with integrated 1G-EPON SoC

September 22, 2011

Broadcom Corp. (Nasdaq:BRCM), a provider of semiconductor systems for wired and wireless communications, unveiled its latest system-on-a-chip (SoC) series designed to address the accelerating Ethernet Passive Optical Network (EPON) market.

EPON ONU chip from Cortina Systems offers smaller BOM, decreased power requirements

September 22, 2011

Cortina Systems, Inc. has unveiled CS803x Integrated Access Platform, the fourth generation of its EPON optical network unit (ONU) chip technology. The CS803x features an embedded 500-MHz CPU and multiple integrated memory options that saves the cost of a separate memory device. It also complies with SIEPON's power saving feature and supports the new IEEE Energy Efficient Ethernet standard.

VCSEL-based 25-Gbps transmission at 850 nearing readiness

September 21, 2011

While module developers work to perfect 4x25-Gbps transmission over singlemode fiber for 100GBase-LR4 and -ER4 applications, technologists have already begun work on enabling similar transmission over multimode fiber. Recent demonstrations have shown progress on both the transmission and reception ends of the spectrum. The demonstrations indicate that 4x25-Gbps products could be readily available once standards are in place.

Billion selects BroadLight’s Helios embedded processors for new Active Ethernet carrier-class routers

September 21, 2011

Billion Electric Co., Ltd. has selected the Helios embedded processor line from BroadLight, a supplier of fiber access processors, in the development of its new Active Ethernet carrier-class router product.

Optical amplifier offers record low noise

September 21, 2011

Researchers at Chalmers University of Technology in Sweden say they have demonstrated an extremely low noise optical amplifier that can extend signal reach by 4X. The phase-sensitive fiber-optic parametric amplifier (PSA) offers a noise figure of 1.1 dB, 3X less than that of conventional EDFAs. If the amplifier can be commercialized – and Chalmers described the technology behind the PSA as “practical” – it could significantly improve the performance of optical communications networks by lessening the amount of interference signals would encounter.
