Chapter 5: Installation Installing an SFP Ethernet interface
Installing an SFP Ethernet interface
In more advanced configurations, there may be an optical or copper Cat5e Ethernet interface
connected to the SFP port of the ODU. Refer to Typical deployment on page 3-2 for diagrams of
these configurations.
Adapt the installation procedures in this chapter as appropriate for SFP interfaces, noting the
following differences from a PSU interface:
• Install an optical or copper SFP module in the ODU (SFP port) and connect the SFP optical
or copper cable into this module using the long cable gland from the SFP module kit. This
is described in the following procedures:
o Fitting the long cable gland on page 5-48
o Inserting the SFP module on page 5-49
o Connecting the cable on page 5-51
o Fitting the gland on page 5-52
o Removing the cable and SFP module on page 5-54
• Optical cables do not require LPUs or ground cables.
• At the remote end of an SFP drop cable, use an appropriate termination for the connected
device.
• If the connected device is outdoors, not in the equipment building or cabinet, adapt the
grounding instructions as appropriate.
• PTP 700 LPUs are not suitable for installation on SFP copper Cat5e interfaces. For SFP drop
cables, obtain suitable surge protectors from a specialist supplier.
• Ground the top LPUs and surge protector to the same point on the ODU (Figure 122).
