SFP and XFP Ethernet Interfaces
The RCM supports the following Ethernet interfaces:
One 10Gbps Ethernet 10G Small Form-factor Pluggable (XFP) optical interface located in port 10
Ten 10/100/1000 Mbps Ethernet Small Form-factor Pluggable (SFP) electrical or optical interfaces located in ports 0
through 9
SFP and XFP ports are Multi-Source Agreement (MSA) compliant
Fiber Optic SFP and XFP Modules
The SFP transceiver is a hot-swappable device that can be plugged into one of the Gigabit Ethernet ports on the front of
the RCM module to link with fiber optic networks. The XFP transceiver module is required for the 10G Ethernet port.

Examples of an Optical XFP, Optical SFP, and Copper SFP
SFP modules come in different forms from different manufacturers. The CMTS does not come with SFP or XFP modules.
Note: Neither SFPs nor XFPs are included with the RCM order; they must be ordered separately.
