Mitsubishi Electric Introduces 10 Gbps DWDM Transceiver Module

Mitsubishi Electric Corporation (President and CEO: Setsuhiro Shimomura) announced today it has developed a 10 Gbps transceiver module for optical communication. This module is the first compact optical transceiver in the world to comply with the DWDM (Dense Wavelength Division Multiplexing) system under the 10 Gbps Form-factor Pluggable Extended Multi-Source Agreement (XFP-E MSA), the industrial standard for 10 Gbps optical transceivers. Sample shipment will begin on October 1. Mitsubishi Electric will display the module at the 32nd European Exhibition of Optical Communication (ECOC), to be held September 24-28 in Cannes, France.


  • Wavelength of 1530-1560nm (DWDM)
  • Transmission distance up to 80km
  • 9.95G-11.1Gbps multi-rate operation
  • Operating temperatures range of -5C-+70C
  • Sample Price: USD 5,000
  • Sample Date: Oct. 1, 2006
  • Production Date: Jan. 2007

Aim of Sale
With the dissemination and increasing volume of high-speed, high-volume communication services such as Voice over Internet Protocol (VoIP), Internet Protocol Television and etc., there has been a rush to expand the communications network in long distance trunk lines and metropolitan areas(a) to keep up with increasing communication traffic. To reduce network setup costs, communication device manufacturers have been working to develop an optical transceiver capable of high-efficiency transmission in a single unit.

Mitsubishi Electric has already developed a 300pin MSA compliant 10 Gbps DWDM transceiver module for optical communication, however there was a need for a more compact transceiver that could handle further increases in transmission speed and volume that could allow for module exchange without cutting electric current during maintenance.

This 10 Gbps optical communication transceiver module resolves all of these problems, and reached a XFP-E multi-source agreement (MSA), a regulation for electric, optical, and mechanical interfaces, in March of this year. It will be the first DWDM compatible XFP-E MSA compliant module in the industry.

Product Characteristics

1) High density transmission up to 480 Gbps
The module is the first in the 10Gbps DWDM industry to be XFP-E MSA(b) compliant. It is capable of high speed, high volume transmission as well as being hot swappable. Using 48 modules per optical fiber, we produced a high-density transmission rate of 480 Gpbs (48 multiplexed wavelength of 10 Gbps) per optical fiber. The new module has also achieved improvements in speed and volume, and is also a 55% reduction in volume from the previous 300pin MSA model.

2) Ease of system construction
We increased transmission range to 9.95G-11.1Gbps by using a high-performance Phase Locked Loop (PLL) circuit also adopted in previous transceivers. This simplifies construction of optical communication systems with varying transmission rates, such as SONET/SDH, 10 Gigabit Ethernet, 10 Gbps Fiber Channel and etc.

3) Lower power consumption using newly developed laser
Using a newly developed Electronic Absorption (EA) laser allows operating temperatures up to 20C higher than existing lasers. Because the new laser can operate in higher temperatures, it has reduced the cost on power consumption for cooling by more than half compared to 300pin MSA compliant modules.
