Summary:
|
Recommendation ITU-T G.959.1 provides physical layer inter-domain interface (IrDI) specifications for optical networks which may employ wavelength division multiplexing (WDM). The IrDIs within the optical transport network (OTN) are provided by unidirectional, point-to-point, single and multichannel line systems. Their primary purpose is to enable transversely-compatible interfaces to span the boundary between two administrative domains. The IrDI specifications include intra-office, short-haul and long-haul applications, without line amplifiers.
This version of this Recommendation includes single channel interfaces up to OTU3 (40 Gbit/s) rate and multichannel interfaces suitable for OTL4.4 (OTU4 striped across four physical lanes).
