*
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-
µ
m fibers has a different specification from the mode-conditioning patch cord for 50-
µ
m
fibers.
**
ITU-T G.652 SMF as specified by the IEEE 802.3z standard.

Specified at transmission wavelength.
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.
