JDSU has added Optical Transport Network (OTN) capabilities to its 100GE test suite. The test platform now offers OTU3 (43GE) and OTU4 (112GE) test features to help transport Ethernet over longer distances for high speed networks.
Optical Transport Networks running on OTU3/4 add the framing, management layer and forward error correction (FEC) on top of Ethernet that is needed for longer distance transmission and for OTN management in a carrier network.
JDSU’s fully comprehensive OTU3/4 feature set:
Provides overhead and payload manipulation as well as monitoring;
Complements the 40GE/100GE product lines to give complete test coverage;
Supports comprehensive test features for the new OTL (Optical Channel Transport Lane) layer; and;
Aligns with JDSU’s existing, industry leading OTU1/2/3 products so customers can easily migrate to the faster speeds.

You just read about JDSU. One of the companies whose work it now carries:
Network Instruments built Network and application performance monitoring. What became of it?
Network Instruments brought Network and application performance monitoring to Networking. That work was distinctive enough to lead to its acquisition by JDSU for US$200M. The standalone name now passes into the archive — but the team and technology continue inside JDSU today. One of 430 names here whose work outlived the company.
You just read about OTN. Here is what it replaced:
SONET / SDH served 1988–2020. What ultimately replaced it?
SONET / SDH a synchronous TDM hierarchy that framed tributaries into standard optical rates (OC-3/12/48...), multiplexed by a master clock, with fast (<50 ms) ring protection over redundant fiber paths. Its job passed to OTN — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
