You can use Quad Small Form-Factor Pluggable Plus (QSFP+), Small Form-Factor Pluggable Plus (SFP+),

SFP transceivers, or RJ-45 connectors to connect the ports on the I/O modules to other network devices.

The RJ-45 connectors and the transceivers used with copper cables come already assembled with their cables.

The transceivers used with fiber-optic cables come separated from their cables. To prevent damage to the

fiber-optic cables and their transceivers, we recommend that you keep the transceivers disconnected from

their fiber-optic cables when installing the transceiver in the I/O module. Before removing a transceiver for

a fiber-optic cable, remove the cable from the transceiver.

To maximize the effectiveness and life of your transceivers and optical cables, do the following:

• Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions

• Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to

prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should

be kept below 0.35 dB.

◦ Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.

◦ Clean the connectors regularly; the required frequency of cleaning depends upon the environment.

In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry

cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.
