Mitsubishi Electric Develops Low Power Consuming 10 Gbps XFP Transceiver Module for Optical Communication.

TOKYO -- Mitsubishi Electric  Corporation (President and CEO: Setsuhiro Shimomura) announced today it has developed a new 10 Gbps transceiver module capable of a 40 km optical communication transmission. The module has the lowest power consumption in the industry1, and complies with the 10 Gbps Form-factor Pluggable Extended Multi-Source Agreement (XFP MSA), the industrial standard for small optical transceivers. Sample shipment will begin on March 6.

Aim of Sale

With the dissemination of high-speed, high-volume communication services such as VoIP (Voice over Internet Protocol), Internet Protocol Television etc., there has been a rush to expand the communications network in long distance trunk lines and metropolitan areas to keep up with sudden increases in communication traffic. To reduce installation costs, there has been strong demand by communication device manufacturers for a small, low power consumption optical transceiver that can provide multiple functions in one optical transmission device.

Mitsubishi Electric has manufactured XFP MSA-compliant 10Gbps optical communication transceivers, but has worked to further reduce power consumption of the device. This new XFP MSA-compliant transceiver module has the industry's lowest power consumption, and is also capable of a 40 km transmission.

Product Characteristics

1) Industry's lowest power consumption (2.5W)

We developed a new low power consumption, light-modulated integrated laser, an optical device with a semiconductor optical modulator and laser diode in one chip that has low wavelength fluctuation even during high modulation. Using this as a light source, we reduced power consumption to 2.5W, approximately 30% less compared to previous model MF-10KSXB003, and the lowest in the industry.

2) Reduced power consumption, potential for increased functions added to single module

By reducing energy consumption to the lowest level in the industry, we can add additional modules without increasing the power capacity of the optical transmission device. This will allow up to a 30% increase in the number of modules that can be added to a single optical communications device and reduce installation costs.

3) 10 Gbps multirate ready eases system construction

Using well-established PLL circuitry2 capable of transmission rates of 9.95-11.1 Gbps will ease construction of optical transmission systems of differing transmission rates, such as SONET/SDH3, 10Gb Ethernet, and 10 Gbps fiber channel4.

2Phase Locked Loop: electronic circuit that can oscillate correctly synchronized output signals with input signals by detecting frequency and phase error of input and output signals and controlling it with a synchronizer, etc.

3Synchronous Optical NETwork/Synchronous Digital Hierarchy: international standard for high speed fiber optic digital communication. It is called SDH mainly in Europe and SONET in North America

4high speed transmission device that connects computers to peripheral devices such as external memory units
