Network Requirements
Before installing the module, review the requirements and specifications referred to in this chapter
concerning the following:
The network installation must meet the requirements to ensure satisfactory performance of this
equipment. Failure to do so will produce poor network performance.
.
XFP 10-Gigabit Ethernet
There are two optional 10‐Gigabit interface port slots on the 7KR4297‐02 and four optional 10‐
Gigabit interface port slots on the 7KR4297‐04 that can support various optional XFP 10‐Gigabit
Ethernet (10 Gbps) standard type fiber‐optic modules. As of the printing of this guide, the
10GBASE‐LR‐XFP, ‐ER‐XFP, ‐ZR‐XFP, and ‐SR‐XFP
are available.
Table 2‐1 provides the cable type, maximum length, and connector type according to each version
of XFP. For complete specifications, refer to “ 10‐Gigabit Ethernet Transceiver Specifications
(XFP) ” on page A‐2.
