1.
Cable distances are based on fiber loss. Additional factors, such as the number of splices and the optical quality of the fiber, can affect cabling distances.
Minimum cabling distance for all types is 2 m according to the IEEE 802.3ae standard.
2.
The Cisco XENPAK-10GB-CX4 transceiver supports link lengths of up to 49.2 feet (15 m) on CX4 cable. Cisco offers four CX4 cables:
CAB-INF-28G-1= (1 meter cable), CAB-INF-28G-5= (5 meter cable), CAB-INF-28G-10= (10 meter cable), and CAB-INF-26G-15= (15 meter cable).

The XENPAK-10GB-LW (WAN PHY) supports a link length of 6.2 miles (10 km) on standard SMF (G.652). The WAN PHY allows

ITU-T G.652 SMF as specified by the IEEE 802.3z standard.
5.
Requires a 5 db 1550 nm fixed loss attenuator for cable distances less than 12.43 miles (20 km). The attenuator is available from Cisco Systems
(p/n WS-X6K-5DB-ATT=). The attenuator is installed on the receiver side of the transceiver.
