• OE Solutions, ARTech, Lightron Inc.
etc. are optical transceiver
companies in Korea, and 10G XFP,
40G XFP optical transceiver are
commercialized
• High quality technology is needed
to face against cheap products
from China
• 100G CFP4 optical transceiver
technology for short distance of
ETRI and optical receiver
technology for this has succeeded
commercializing with transferring
technology to Korea’s optical
transceiver company.
• Compact and high-sensitivity 4x25G
ROSA for long distance 100G CFP4
optical transceiver has yet
commercialized in global, therefore
100GE optical transceiver module
technology is needed.
• Finisar, Opnext, Avago, Sumitomo,
which are global leading optical
module companies, are sel ing 100G
CFP, CFP2 and CFP4 module for
short distance, and 100G CFP4 for
40km transmission is yet ready for
launch.
• Current circumstance is promoting
expansion of market share by M&A
with leading companies as center,
and especial y these M&A are not
producing key components to rival
companies so that its own
components supply system are
being a vertical integration.
- Increase in 100GE optical transceiver demand for Ethernet optical signal
transmission
- Increase in compact and low-power product demand for surface area and
power consumption decrease
- In case of 40km, since commercialized product is yet to be launched,
easy to enter the market

High-speed and high-density PCB technologies
▶ Applications
• Large-scale Data Center
- Large capacity router and switch
• Ultra High-Speed Networking Infrastructure
- Client interface of ROADM system
• Wireless Backhaul network.
- Client interface of PTN equipment
▶ Effect of technology adoption
• Financial effect of technology adoption
- 40km 100GbE CFP4 product is not commercialized yet, so if domestic company
adopts this technology, entering global market and occupation is easier
- ETRI has LAN-WDM 4ch APD-ROSA technology which is element technology of
40km 100GbE CFP4 optical transceiver
• Ripple Effect of Technology Industrialization
- Global market of mass Ethernet optical transceiver extends not only to large
Data Centers but also to wireless backhaul for mobile network, and so on. For
the case of 100GE CFP4, its smal er surface area makes it more efficient in
terms of the overal system’s degree of integration than the original CFP2.
- Also, 40km 100GbE CFP4 product is not commercialized yet, so when
industrialized, entering global market wil be easier because of occupation.
