Making Fiber Attachments
If the node you intend to connect is located at a remote area, you may use
fiber optics to link this device to the Switch. Fiber attachment to the system
is available through both the DES-108FL and DES-108FX modules. These
modules come with two switched fiber-optic ports, providing fiber links to
remote nodes.
Each fiber-optic port on these two modules comes with two connectors; one
for reception (Rx) and the other for transmission (Tx). They come with
protective covers to protect the lens inside the connectors from dust, which
could alter the intensity of light coming in and out of the port. Do not
remove these protective covers unless you are ready to connect the port.
You will need a 62.5/125
µ
m
multimode fiber cable in the connection. This
cable can be up to 2 km long.
NOTE:
You do not need to turn off the Switch when
making network connections; just plug the
cables into the ports.
Perform these steps to connect nodes to the Switch using fiber-optic cables,
1.
Depending on the number of nodes and which type of partner you
intend to connect (if 10BASE, select DES-108FL, and if 100BASE,
select DES-108FX) install the appropriate number of DES-108FL
and/or DES-108FX modules into the Switch. Note that each module
provides two switched fiber-optic ports. For information on the
installation procedure, see the
Port Module Installation
section of
Chapter 3,
Installation
.
2.
Obtain a 62.5/125
µ
m
multimode fiber cable. Ensure that this cable
does not exceed 2 km.
3.
Select a fiber-optic port to connect the node.
