Due to the dual media (single-mode and multimode) support of the
1000BASE-LX module, an offset-launch mode-conditioning patch cord
assembly is required to meet the specifications for multimode (MMF)
operation. This patch cord is not required for single mode (SMF)
operation. Patch cords come in various lengths and can be ordered
from Siecor Operations (800-743-2675, fax: 828-327-5973). The
following table lists the part number information:
