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.

Optical Specifications
Table 2 specifies the optical parameters for the SFPs. Both receiver power and channel insertion loss
specifications must be met for guaranteed operation.

Maximum channel insertion loss is defined for maximum distance guaranteed as specified in Table 1 and by fiber type. When
links are deployed over shorter distances, additional channel insertion loss may be allowed.
Dimensions
Dimensions (H x W x D): 8.5 x 13.4 x 56.5 mm. Cisco SFPs typically weigh 75 grams or less.
