Note:
*A mode-conditioning patch cord, as specified by the IEEE standard, is required regardless of the span length. Note how the mode conditioning patch cord for 62.5-μm fibers has a different specification from the mode-conditioning patch cord for 50-μm fibers.
**ITU-T G.652 SMF as specified by the IEEE 802.3z standard.
***Specified at transmission wavelength.
