Chapter 1 General Troubleshooting

Fiber and Cabling

Tip To prevent overloading the receiver, use an attenuator on the fiber between the card transmitter and the receiver. Place the attenuator on the receive transmitter of the cards. Refer to the attenuator documentation for specific instructions.

Tip Most fiber has text printed on only one of the two fiber strands. Use this to identify which fiber is connected to Tx and which fiber is connected to Rx.

1.8.2.1 Crimp Replacement LAN Cables

You can crimp your own LAN cables for use with the ONS 15327. Use a cross-over cable when connecting an ONS 15327 to a hub, LAN modem, or switch, and use a LAN cable when connecting an ONS 15327 to a router or workstation. Use #22 or #24 AWG shielded wire with RJ-45 connectors, and a crimping tool. Figure 1-26shows the layout of an RJ-45 connector.
