J. Yoshida et al., PROSPECT OF COST REDUCTION TECHNOLOGIES FOR OPTICAL AND ELECTRICAL DEVICES FOR OPTICAL ACCESS NETWORKS, NTT review, 9(6), 1997, pp. 49-54
The key issue to achieve optical subscriber systems is to reduce the c
ost of components and devices. In particular, optical devices and LSIs
used in the ONU of FTTH systems, which NTT has intensively studied, n
eed to be reduced in cost. This paper describes the basic concept and
technologies for achieving drastic cost reduction in these devices.
