Fujitsu demonstrates 100Gbps Coherent Transceiver at OFC/NFOEC 2012

February 29, 2012

Rapid increase in the volume of communications traffic has come from the spread of new services such as mobile broadband using smart phones, cloud computing and on-line streaming. This has created a great demand for next-generation 100Gbps optical networks. FOC has been the industry leader in the development of ultra–high speed optical components and modules needed to meet this requirement. On September 19, 2011 FOC announced that in April, 2012 it will be releasing a coherent transceiver module as defined in the OIF 100GLH-EM specifications for 100Gbps digital coherent transmission systems. This module's performance will be demonstrated at FOC's booth (#2317) at the OFC/NFOEC 2012 show in Los Angeles from March 6-8, 2012.

In this demonstration, both a low dispersion path and a very high dispersion path between the optical transmitting port and the optical receiving port of the 100Gbps optical transceiver will be prepared. Optical switching between the two paths will be performed to simulate the condition seen when routes are changed in actual transmission systems. The demonstration will show that FOC's optical transceiver has both the high-speed response required to handle the case where two optical routes with different dispersions are rapidly switched and the dispersion tolerance necessary to handle long-distance transmission.

This product will help enable the development of high-performance optical network equipment with the capability of transmitting 100G Ethernet signals as defined in the OTU4 optical interface of ITU-T (*4)G.709 over backbone networks.

(Note) The 100G Digital Coherent Signal Processing LSI (DSP-LSI) in the digital signal processor is made by NTT Electronics Corporation. The DSP-LSI incorporates the outcome of "R&D on High Speed Optical Transport System Technologies" supported by the Ministry of Internal Affairs and Communications of Japan. (*5)

Glossary & Notes

（*1） Digital coherent transmission systems:
Converts the received optical signal to an electrical signal in the optical receiving section after combining the received optical signal with a local reference light, and then compensates the waveform distortion that occurs in the optical transmission path by digital signal processing. This technique allows for significant reduction in system cost through the elimination of optical dispersion compensators and optical amplifiers (for loss compensation).

（*2） OIF
Acronym for Optical Internetworking Forum. The OIF is an organization that promotes standardization for the equipment and components used in optical networks

（*3） OFC/NFOEC
Acronym for Optical Fiber Communication Conference and National Fiber Optic Engineers Conference

（*4） ITU-T
Acronym for International Telecommunication Union-Telecommunication sector. It is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU) and coordinates standards for telecommunications.

（*5） DSP-LSI
Second generation DSP-LSI utilizing built in high performance forward error correction with soft decision decoding to enable high performance transmission.
