* Minimum cabling distance for optical XENPAK modules (-LX4, -SR, -LR, -ER) is 2m, according to the IEEE
802.3ae standard, and minimum cabling distance for -LRM modules is 0.5m, according to IEEE 802.3aq
standard.
** Data based on standard G.652 SMF. Even though dispersion-shifted fiber enables reducing signal dispersion
to travel longer distances, the signal attenuation still limits its distance.
*** Requires 5 dB 1550 nm fixed loss attenuator for < 20 km. Attenuator is available as a spare. The part
number is WS-X6K-5DB-ATT=.
**** Links longer than 30 km are considered engineered links.

Table 2 shows the main optical characteristics for the Cisco XENPAK modules. The Cisco
XENPAK-10GB-CX4 is not an optical module and therefore is not listed in the table.

* The launch power shall be the lesser of the class 1 safety limit or the maximum receive power. Class 1 laser
requirements are defined by IEC 60825-1: 2001.
** WS-G6488 has the same optical parameters as XENPAK-10GB-LR.
*** WS-G6483 has the same optical parameters as XENPAK-10GB-ER.
