The single-fiber bidirectional WDM system uses only one optical fiber to transmit optical signals in two directions at the same time. The optical signals in the two directions should be arranged at different wavelengths.
Configuring an EPLAN service as a ring is not recommended. If the EPLAN service is configured as a ring, the STP protocol must be enabled on the network to prevent broadcast storms.
WDM multiplexes the optical signals at multiple rates (wavelengths) over one fiber for transmission. The digital signals carried by these optical signals must have the same rate and data format.
The interval between two adjacent pointer justification events is at least ( ) frames.
