Abstract

We have previously proposed and implemented a novel low cost 100G transmission system which has the 1 RU only size and a small form factor [1]. In this paper we further develop a LLF (Link Loss Forward) feature which can monitor the health of this 100G system and make a necessary link failure management. The mechanism is based on the fast FPGA insertion/desertion processing and the usage of un-used overheads of OTN digital wrapper as an in-band tunneling, so that the remote link failure relay, link failure isolation, and alarm report can be done properly. Finally, when the link failure is re-covered, the system will detect it and do automatic recovery as well as alarm clearance accordingly.
