Loss Of Lane Alignment (LOL) is declared on 100G interfaces when it has not been possible to successfully recover the Logical Lane Marker (LLM) from the logical lanes and then re-assemble the OTU4 frame. During the lane recovery process the LLM will be present in a lane every 16320 bytes, when the same LLM…(Read More)

OTN uses a similar multi-lane mechanism to 100G Ethernet to achieve 100G rates. The parallel interfaces are defined in an appendix of the G.709 recommendation.  The recommendation includes definitions of parallel interfaces for both 40G and 100G rates and within this a new signal was defined for parallel interfaces – the Optical Channel Transport…(Read More)
