Fujitsu introduces the world’s first 100G CFP2 Transceiver supporting the IEEE 100GBASE-ER4 and ITU-T G.959.1 OTU4 standards for 40km transmission

July 09, 2014

- For use in IP and Metro Networks requiring compact high capacity optical network equipment -

Kawasaki, Japan, July 9, 2014- Fujitsu Optical Components Limited (FOC) announced today that the world’s first 100G CFP2 (*1) transceiver to support the IEEE (*2) ER4 (40km transmission with single-mode fiber) and ITU-T (*3) G.959.1 standards will be released in the fourth quarter of 2014. This product will help facilitate high-capacity and compact 100G optical network equipment for use in the IP Networks between datacenters and metro networks.

New services such as mobile broadband using smart devices, social networking, cloud computing, and on-line streaming have led to a rapid increase in the volume of communications traffic. This has created a great demand for 100G optical networks. These 100GbE optical networks are spreading as a result of the ever increasing demand for larger capacity, higher port density, and lower cost in the IP networks that connect the data center to the metro network. CFP transceivers (as defined in the CFP MSA (*4)) that cover the 100GbE LR4 (10 km with single mode fiber) and ER4 standards are already popular in the market. CFP2 100GbE LR4 transceivers (as defined in the CFP2 MSA) which offer smaller size and lower power consumption in comparison to CFP transceivers have now started to ship into the market as well. Due to technical difficulties, CFP2 transceivers which fully support the IEEE 100GBASE-ER4 and ITU-T G.959.1 OTU4 (4L1-9C1F) standards have not been released into the market though until now.

FOC has successfully commercialized the world’s first 100G CFP2 transceiver to be fully compliant with both the IEEE 100GBASE-ER4 and ITU-T G.959.1 OTU4 standards (4L1-9C1F). This product will be used in the compact high-capacity 100G optical network equipment used in the IP Networks that exist between the datacenters and Metro Networks.

Key Features

  1. Full support of IEEE 100GBASE-ER4 and ITU-T G.959.1 OTU4 standards (4L1-9C1F)
    FOC’s CFP2 module achieves stable receiver sensitivity characteristics over a wide input dynamic range through the use of a SOA (*5) which is placed in front of the receiver. This technology enables the module to be able to fully support both the IEEE 100GBASE-ER4and ITU-T G.959.1 OTU4 standards (4L1-9C1F). The module is also fully interoperable with the CFP transceivers which have already been installed in the field.
  2. Low power consumption
    Optimized control of the optical devices (SOA, TOSA (*6) and ROSA (*7)) has enabled the power consumption to be lowered to 9 watts or less (CFP2 MSA Class3 compliant).
  3. High density mounting technology
    FOC has developed technology to allow the mounting of multiple optical devices and control circuits into a limited space (about 37% in volume compared to CFP transceiver) with high reliability.

FOC plans to release a new lower power consumption CFP2 LR4 transceiver (8 watt or less) supporting the LR4 standard at the same time. This transceiver is targeted to meet the needs of a wider range of users, together with CFP LR4 and CFP ER4 transceivers that are already at the mass production stage.
