¿µ¹®³»¿ë¿ä¾à Recommendation ITU-T G.698.3 provides optical parameter values for physical layer interfaces of seeded dense wavelength division multiplexing (DWDM) systems primarily intended for metro applications.
Applications are defined using optical interface parameters and values for single-channel and multichannel interfaces of seeded DWDM multichannel optical systems in point-to-point applications. This Recommendation uses a system architecture comprising a head-end, connecting to the tail-end equipment (TEE) through a black link. The head-end houses a set of transmitters and receivers and an optical multiplexer and demultiplexer (OD/OM) in addition to a seed signal source. A single bidirectional fibre is used to connect the head-end to the passive OD/OM. Connection between OD/OM and remote TEE is also bidirectional. At the tail-end, all transmitters use a seed signal to lock to the desired transmission wavelength. The initial version of this Recommendation includes seeded DWDM application at 1.25 Gbit/s with 100-GHz channel frequency spacing.
