Title:
OPTICAL CROSS-CONNECT DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/005170
Kind Code:
A1
Abstract:
Provided is an optical cross-connect device whereby, in an optical node in an optical network, it is possible to easily support even an increase in the number of optical fibers between optical nodes. In an optical cross-connect device (OXC), an optical cross-connect unit (OXC1) comprises an internal connection input port (Pni1) and an internal connection output port (Pno1) for expansion, which are not connected to other optical cross-connect units. By connecting an internal connection output port and an internal connection input port of an optical cross-connect unit for expansion (OXCA) with the respective internal connection input port and internal connection output port for expansion of the optical cross-connect unit (OXC1), it is possible to inexpensively and easily install a new optical cross-connect unit in response to increases in the optical fibers which are connected to the optical node.
