XENPAK 10-Gigabit Ethernet
There are two optional 10‐Gigabit interface port slots on the 7KR4290‐02 that can support various
optional XENPAK 10‐Gigabit Ethernet (10 GbE) standard type fiber‐optic modules. As of the
printing of this guide, the 10GBASE‐LR, ‐ER, ‐LX4, and ‐SR are available.
Table 2‐1 provides the cable type, maximum length, and connector type according to each version
of XENPAK. For complete specifications, refer to "10GBASE XENPAK PHY Specifications" on

1. The 10GBASE-ER XENPAK requires a minimum of 5 dB attenuation or a cable length of about 10 km.
The uplinks have one fiber‐optic interface with an SC connector. Depending on the XENPAK and
fiber‐optic cable used, the signal can be driven to a maximum distance of 33 m (108 ft) to 40 km
(24.85 miles).
The device at the other end of the fiber optic connection must be a standards‐compliant product
with a matching XENPAK interface.
