Abstact-This paper discusses the key design issues to apply both CWDM (Coarse Wavelength Division Multiplexing) and Optical Hub technology for an Access Network. The purpose is to reconsider the characteristics of both optical circuits (such as a splitter, a coupler, a laser diode, a photo diode) and CWDM technology, and to try to find better optical components deployment in an access area. The core of the network is composed of optical components, i.e., Optifal Hub and fibers. CWDM functionality (such as LD and PD) is provided by newly designed ONICs (Optical Network Interface Card) located at a station site. The proposed accessnetwork structure has advantages in simplicity and scalability. Tesd bed implementation is included.

INTRODUCTION
For Internet users the access network has two choices one is a fiber such as FTTH and other is radio such as IEEE802.11. From a network construction view point, the fibernetwork structure is important becauser it also supports radio access by connectiong an antenna to a network.
This paper discusses the near future choices of a fiber network structure in access area. The premises for starting the discussion are explained.
1) User's Internet traffic continues to increase.
2) Optical fiber has enormous transmission capacity, ie., 200THz so once it is installed in a access area, the capacity increase will be available with replacing both ends terminationg devicces.
3) Present optical device technologies are limited within fibers, amps, filters, splitters/couplers, and no logical device will soon be available in access area. So the core of the network is preferable to be transparent for all optical signals.

Three forecasts above suggest that the advantage of a fiber network is the scalability for the future. A similar netwrk structure transition reminds us of that once a twisted pair cupper cable increased the transmission capacity by replacing terminationg telephone with an ADSL modem. A fiber based optical transparent network will be very practial solution because it may provide huge transmission capacity by applying future advanced optical device technologies.
The advantage of a transparent optical WDM star network is pointed out in 1994.[1] Over ten years, many technical proposals are appeared.[2] The discussion items are "packet switch or circuit (wavelength) switch", "optical packet switching or optical burst switching", "wavelengh routing" and "broadcast and select control".
In the discussions about passive optical network, a star coupler has been a key component. The paper re-examines a principal function of a star coupler by going back to the fundamental optial guide connections between a splitter and a coupler. By doing so, the paper explains the connection is closely related with an optical channel state allocation between stations. Also, it shows a star coupler function could be enhanced to a passive optical circuit module named Optical Hub.
