This is the CE version of the LCNE2 board, used to extend the LCN to a remote location using fiber optic cable. The normal arrangement of LCNE2 boards consists of four boards, one each for the A and B cables, at both ends of the extension. This CE version is compatible with the non-CE LCNE2. The LCNE2 card uses SMA Type fiber optic connectors.

This part is no longer manufactured by Honeywell, and has been replaced by the XLCNE2, which is not compatible with the LCNE2. WPC normally has LCNE2 boards in stock.
