DES-108FL
This Fiber-Optic Inter-Repeater Link (FOIRL) module provides two
switched fiber-optic ports for creating fiber-optic links. Each of these ports
has two connectors; one for reception (Rx) and another for transmission
(Tx). When creating a link, ensure that the Rx connectors connect to the Tx
connectors, and vice versa.
Each connector comes with a protective cover to prevent dust from
accumulating inside the connector. Do not remove this cover unless you are
ready to connect the port--too much dust may alter the intensity of light
coming in and out of the port, which could lead to data interpretation errors.
DES-108FX
This module provides two switched fiber-optic ports for creating fiber-optic
links. Each of these ports has two-in-one connectors. Set the module to full-
duplex or half-duplex mode by the jumpers on the back panel (see
instructions and diagram on the next page).
