You are a network technician for a small corporate network. Your manager has decided to switch to a new ISP. The network needs to be moved to the new ISP so that the old one can be cancelled. The new ISP has run a fiber optic line directly to the back of the fiber patch panel in the basement Networking Closet, but the NSA device doesn't have any fiber ports. Because the NSA doesn't have any fiber ports, you need to use a media converter to convert from a fiber optic cable to an Ethernet cable. Most media converters use SFP ports so they can convert multiple form factors. The media converter in this lab already has a fiber SFP module installed. Use the following information to make the proper connections: The ISP is connected to ports 23 and 24 of the fiber patch panel.Port 23 is Tx.Port 24 is Rx. Use the color coding on the end of the fiber optic cables to identify which end is Tx and which is Rx.Connector A (white or red) is Tx.Connector B (black) is Rx. When connecting fiber optic cables, connect the transmit (Tx) port on one device to the receive (Rx) port on the other device. The fiber cables in this lab have already had their Rx and Tx connectors switched as necessary. You can view component information in the Details window on the Specification tab.
