Document Type and Number:
Japanese Patent JP4007860
Kind Code:
B2
Abstract:
A transmission apparatus for coupling an optical signal transmission section and an electrical signal transmission section through an opto-electric two-way conversion unit, where the electrical signal transmission section is comprised of a SONET/SDH signal processing function unit and a generalized multi protocol label switching (GMPLS) function processing function unit cooperating with that function unit and where the optical signal transmission section is comprised of an optical add/drop function unit for transferring an optical signal with the electrical signal transmission section through the conversion unit and an optical cross-connect function unit for switching paths in wavelength units of the optical signal with the electrical signal transmission section, whereby the capital cost and running costs of an optical network for transmitting an IP signal can be greatly reduced.
