DES-1008M User’s Guide
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 μm 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 μm multimode fiber cable. Ensure that this cable does not exceed 2 km.
3.Select a fiber-optic port to connect the node.
