- High speed and high capacity transmission performance for use in backbone networks -
Kawasaki, Japan, September 19, 2011- Fujitsu Optical Components Limited (FOC) announced today that on April, 2012 it will be releasing a coherent transceiver for 100Gbps digital coherent transmission systems (*1) as defined in the OIF (*2) 100GLH-ME-01.0 specifications. This product will help to enable the development of optical network equipment with 100Gbps Ethernet transmission capabilities on backbone networks.
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 demand to put the research and development that has gone into 100Gbps optical networks into practical use.
The ITU-T (*3), which has been promoting the standardization of the OTN (Optical Transport Network) to transport 100G Ethernet signals over backbone networks, has created the OTU4 optical interface standard in Recommendation G.709. The OIF is also promoting international standardization for 100Gbps Long-Haul DWDM Transmission Modules.
Using the technologies described below, FOC has successfully commercialized a 100Gbps coherent transceiver as defined in the OIF 100GLH-ME-01.0 specifications for 100Gbps digital coherent transmission systems. 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 G.709) over backbone networks.

（*1） Digital coherent transmission systems:
Uses DP-QPSK modulation and compensates the waveform distortion that occurs in the optical transmission path by digital signal processing in the optical receiving section. This technique allows for significant reduction in system cost through the elimination of optical dispersion compensators and optical amplifiers (for loss compensation).
Acronym for Optical Internetworking Forum. The OIF is an organization that promotes standardization for the equipment and components used in optical networks
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.
Second generation DSP-LSI utilizing built in high performance forward error correction with soft decision decoding to enable high performance transmission.
Acronym for Dual-Polarization Quadrature Phase Shift Keying. It is a method of phase modulation for digital signals, in which 2 bits of data are allocated to each of 4 modulated optical phases (0, 90, 180, 270°) for both P-polarized and S-polarized light.
