Fujitsu Develops 4”x 5” 100G OIF 168pin Coherent Transceiver supporting 2nd Generation OIF 168pin Module Specifications

September 22, 2014

- For use in Core Networks requiring compact, low power consumption and low cost optical network equipment -

Kawasaki, Japan, September 22, 2014- Fujitsu Optical Components Limited (FOC) announced today that it has successfully developed a 4" x 5" 100G OIF (*1)168pin Coherent Transceiver for digital coherent transmission systems (*2) as defined in the 2nd generation OIF 168pin module specifications (100GLH-ME-02.0). This product will be released in the first half of 2015. This product will help facilitate compact, low power consumption and low cost 100G optical network equipment for use in core networks.

Due to the recent rapid increase in the volume of communications traffic, 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. For core network applications the 5" x 7" 100G OIF 168pin Coherent Transceiver defined in the OIF 168pin module specification (OIF-MSA-100GLH-EM-01.0) for long distance and high capacity transmission systems has been deployed. For future applications, a smaller size, lower power consumption and lower cost coherent transceiver as defined in the 2nd generation OIF 168pin module specifications (100GLH-ME-02.0) is needed.

FOC has successfully developed a 4" x 5" 100G OIF 168pin Coherent Transceiver for digital coherent transmission systems as defined in the 2nd generation OIF 168pin module specifications (100GLH-ME-02.0). This product will help facilitate compact, low power consumption and low cost 100G optical network equipment for use in core networks.

Key Features

  1. Compatible with the first generation 100G coherent transceiver
    An OIF 168pin connector compatible with the first generation 100G coherent transceiver provides the electrical interface. The module conforms to OIF-MSA-100GLH-EM-02.0 which enables replacement of the first generation coherent transceiver with this product without need for a change in the board design. Interoperability with first generation 100G coherent transceivers is also guaranteed.
  2. Nyquist filtering function
    This product has the capability to perform Nyquist filtering on the optical signal through digital signal processing (*3). This enables support for high density WDM transmission using narrowband optical filtering.
  3. Development of small circuit design and high density mounting technology
    The low power 100G Digital Coherent Signal Processing LSI (LP-DSP) made by NTT Electronics Corporation is used to compensate waveform distortion. In-house compact optical LN modulators and integrated coherent receivers are also used in the module. High density mounting and the use of circuit design technology that reduces the circuit scale has enabled a reduction in size of 40% and a reduction in volume of 50 % when compared to the first generation (5" x 7") coherent transceivers.

Additional Information

Glossary & Notes

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

(*2) An optical reference is combined with the incoming optical signal to produce an electrical signal out from the receiver. The waveform distortion that occurs in the optical transmission path is then compensated for 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) Band limiting filter design that does not create inter-symbol interference in adjacent channels. The use of Nyquist filtering allows for higher density WDM systems.
