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.
