Fujitsu Introduces Cutting-edge 100G Optical Component and Module Solutions at OFC/NFOEC 2013

March 15, 2013

Rapid increase in the volume of communications traffic has come from the spread of new services such as mobile broadband using smart devices, social networking, cloud computing and on-line streaming. This has created a great demand for 100G optical networks. The requirement for Core Networks to handle larger capacity and longer distance on their links has led to a spread of 100G optical networks using digital coherent transmission systems (*2). Similarly, the requirements on IP networks between data centers and metro core networks to achieve larger capacity, higher port density, and lower cost has led to the spread of 100 GbE optical networks.

FOC has been the industry leader in the development of ultra–high speed optical components and modules needed to meet this requirement. FOC released its 100G coherent transceiver (as defined in the OIF (*3)100GLH-EM specifications) for 100G digital coherent transmission systems and its 100GbE CFP LR4/ER4 transceiver (compliant with the CFP MSA) for 100GbE networks in advance of other companies. FOC will now newly introduce a 100 GbE CFP2 transceiver intended for LR4 applications as well. Combined with its 100G DP-QPSK (*4)LN modulator (first in the world) and integrated receivers for use in coherent transceiver applications, FOC truly provides a total solution to a broad range of customer requirements at 100 Gbps.

At OFC/NFOEC 2013, FOC will introduce its latest product line-up and future product roadmap for 100G coherent and CFP/CFP2 transceivers, 100G DP-QPSK LN modulators, and 100G DP-QPSK integrated receivers. This exhibition will show that FOC can support the customer's total needs for 100G optical components and modules.

【100G Coherent Transceiver】
This product is defined in the OIF 100GLH-EM specification for 100G digital coherent transmission systems. Digital signal processing has been applied to compensate for waveform distortion which results in high tolerance to optical dispersion. High performance and reliability have been achieved by using FOC's in house 100G DP-QPSK LN modulator and 100G DP-QPSK integrated receiver.

【CFP2 Transceiver】
This product is compliant with the CFP2 MSA specifications for LR4 applications in 100G Ethernet networks (CFP2 transceiver for ER4 applications is now under development.). The CFP2 transceiver uses a 28 x 4Gbps lane electrical interface compliant with the CEI-28G-VSR specification. The introduction of this new interface enables compact size (about half width of the current CFP) and low power consumption (about 1/3 of the current CFP) transceiver.

【100G DP-QPSK LN Modulator】
This product is a Mach-Zehnder modulator made from Lithium Niobate (LiNbO3) designed to meet the OIF specifications for 128 Gbs (32 Gbaud) DP-QPSK applications. The modulator incorporates the DP-QPSK optical modulation circuit, polarization beam combiner and monitor photodiode all inside of a compact package. The FOC design allows for both wide bandwidth and low drive voltage operation.

【100G DP-QPSK Integrated Receiver】
This product is a 100G integrated receiver compliant with the OIF specifications for 100Gbps digital coherent receiving systems. The integration of 90° Hybrids (*5), Balanced Receivers (*6)and Polarizing Beam Splitters all into a single package by PLC (*7)and micro-assembly technologies allows to realize a compact, low-cost and high-performance 100G integrated receiver.

In addition, Fujitsu Laboratories Ltd will demonstrate 400GbE transmission technology using DMT (Discrete Multi-Tone) modulation format in the FOC booth as "DMT Modulation Format 400GbE Transmission Demonstration'.

FOC will also participate in OIF Interoperability 2013 at OIF booth #2769.

OIF Interoperability 2013
More than ten OIF member companies will unite under the banner of the Optical Internetworking Forum to showcase multi-vendor participation in OIF Interoperability 2013 – Enabling the Next-Generation of 100G Optical Modules. The OIF's PLL demonstration will showcase the draft CEI-28G-VSR implementation agreement key to enabling the next generation of more efficient, smaller form factor 4x 25G Optical Modules.
A public demonstration of the event will be on display March 19-21, 2013 at OFC/NFOEC in Anaheim, CA, OIF Booth #2769. Additional information can be found at http://www.oiforum.com/public/OIF_Interoperability_2013.html

Glossary & Notes

（*1）Acronym for Optical Fiber Communication Conference and National Fiber Optic Engineers Conference

（*2）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).

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

（*4）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.

（*5）Optical mixer component that is used for coherent signal demodulation purposes in heterodyne and intradyne detection systems. The hybrid mixes the incoming optical data signal with light from an input optical reference source and guides the combined signal to the balanced receivers.

（*6）A receiver consisting of two photodiodes which receives differential optical output from delay line interferometers and 90° Hybrids. Improved receiver characteristics are achieved by using the difference between the two photodiode currents.

（*7）Acronym for Planar Lightwave Circuit. Optical circuit chip on a silicon or quartz substrate containing optical waveguides with accuracies on the order of an optical wavelength
