Agreement Reached to Transfer NEC's Magneto-resistance Sensor Business to Murata

NEC Corporation and Murata Manufacturing Co., Ltd. reached an agreement to transfer the magneto-resistance (MR) sensor business of NEC and NEC Yamanashi, Ltd., a wholly owned NEC subsidiary, to Murata. Under the agreement, the transfer is scheduled to be complete by June 1, 2013. After this business transfer takes place on June 1, 2013, Murata will be integrating NEC’s MR sensor business technology assets and expertise on top of their own technologies well accepted in the electronic component market. We would highly appreciate your continued support and interests.

Long History with Optical Communications Industry

NEC has been developing and manufacturing optical transceivers for more than 30 years since the dawn of the optical communications era. Based on this extensive experience, we provide high-reliability products that have received a high reputation from customers. Our product support structure includes the North American and European markets in addition to Japanese market.

NEC provides the following four optical devices as main products:

Optical Transceivers for Backbone Network

NEC offers 40Gbit/s and 100Gbit/s optical transceiver using digital coherent technologies, which realize ultra-long haul transmission over 2,000 km, as well as high-capacity with single carrier.  These transceivers are designed for DWDM optical systems and high-speed routers by applying standard MSA from factor for each bit rate.

Small size 10Gbit/s Hot pluggable transceivers for SFP+ compliant enable high-density installation of optical transmission equipment in 10G SONET/SDH and Ethernet systems. They can help reduce the size and cost of system implementation.

Two product forms: MSA-compliant SFP and Compact SFP. An extensive set of data rates, transmission distances, and optical-connector shape, monitoring characteristics are ready. And furthermore the highly integrated CSFP (Compact Small-Factor Pluggable transceiver) will enable network system vendors to increase port density and data throughput, while reducing network equipment cost.

Features

Full compliant with IEEE 802.3av PRX-D3/PR-D3

  • Integrated 10G/1G downstream transmitters and 10G/1G dual-rate receiver
  • Typical power consumption is 2W
  • Burst RSSI (Received Signal Strength Indicator)
  • Burst LOS (Loss of Signal)

MR sensor developed by NEC is integrated circuits in a small package with higher sensitivity and better stability for a magneto-resistive sensor compared with ordinary one.

It operates excellent performance for position and rotation detection due to non-contact type sensor, and it outputs a digital signal through the state of art ICs.

NEC's MR sensors are of outstanding performance and of easy handling at user site, and are widely employed for various products such as cellular phones, Laptop PCs, hot water supplies, gas-meters, etc.
