*Minimum cabling distance for -LR, -SR, -LX4, -ER modules 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.
**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 X2 module. The Cisco X2-10GB-CX4
is not an optical module and therefore is not listed in Table 2.

*Transmitter and receiver power is in average, unless specified.
**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.
***Both average and OMA specifications must be met simultaneously.
****Even though the receiver can tolerate a wide wavelength range, the specifications are guaranteed for a
signal within the transmit wavelength range
