Fujitsu Develops CFP2 ACO Transceiver for Next Generation Large Capacity Optical Network Equipment

March 19, 2015

- For use in next generation optical network equipment requiring high performance, high density mounting, and low power consumption -

Kawasaki, Japan, March 19, 2015 - Fujitsu Optical Components Limited (FOC) announced today that it has successfully developed the mass production technology for a compact, low power consumption CFP2 ACO (*1) transceiver by using new in-house optical devices (compact semiconductor optical modulator and ultra-compact integrated coherent receiver). This product will help facilitate high performance, high density mounting, and low power consumption in optical network equipment. This product will be released in the third quarter of 2015.

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 coherent transmission systems (*2). In the near future, 100G optical networks using coherent transmission systems will also spread into metro networks and data center applications. High density mounting in next generation optical network equipment requires downsizing the optical module portion to the same size as a CFP2 transceiver and mounting the DSP (with the high power consumption) on the mother board. Although new technologies were tried over the world with the aim to downsize the required optical devices and achieve high optical output power, no solution has reached product level until now.

Through the downsizing of optical elements and the development of high density packaging and high accuracy mounting technology, FOC has successfully developed the mass production technology for new small size in-house optical devices (compact semiconductor optical modulator, ultra-compact integrated coherent receiver) and a CFP2 ACO transceiver using those devices. This product supports not only 100G DP-QPSK but also 200G DP-16QAM transmissions. This product will help facilitate high performance, high density mounting, and low power consumption optical network equipment. This product will be released in the third quarter of 2015.

Key Features

  1. Compliant to OIF CFP2 ACO standard
    The coherent transceiver has the same interface as the CFP2 MSA transceiver which is commonly used in 100G Optical Ethernet applications and conforms to OIF (*3) CFP2 ACO class 1/class 2 standard. This product enables support to metro network applications.
  2. Using compact devices and supporting 16QAM transmission
    In-house compact semiconductor optical modulator and integrated coherent receiver are used in the transceiver. FOC's expertise in optical device control technology has enabled the module to remain highly stable across environmental changes. The transceiver is compliant to the Class 2 standard and supports 16QAM transmission by using a linear modulator driver.
  3. Achievement of high optical output power
    High density mounting and the use of circuit design technology that reduces the circuit scale enables us to mount an optical amplifier in the compact size CFP2 transceiver. High optical output power of more than -2dBm was achieved with 16QAM modulation (which has a narrower modulation amplitude compared to QPSK modulation).

This includes development results by Photonics Electronics Technology Research Association (PETRA) with support from New Energy and Industrial Technology Development Organization (NEDO).

FOC plans to demonstrate this product on our booth (#900) at OFC 2015 which is scheduled to take place from March 24 to 26 in Los Angeles, California, USA.

Glossary & Notes

(*1) ACO: Acronym for Analog Coherent Optics

(*2) An optical reference is combined with the incoming optical signal to produce an electrical signal out from the receiver. The waveform distortion that occurred 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) Acronym for Optical Internetworking Forum. The OIF is an organization that promotes standardization for the equipment and components used in optical networks.
