Duplex fiber-optic wiring (0566-1197, 0566-1198, 0566-1199, or 0566-1200 only)
Use the transceiver U1 on the duplex fiber-optic media card to connect 4100ES NICs across parts of a 4120 network. Figure 22 shows how two
network nodes are connected via fiber-optic cable.
• Do not mix single-mode and multi-mode cards on the same link, that is, do not connect a single mode right card to a multi-mode left card.
• The 4100 series duplex fiber cards are not compatible with dual fiber-optic media cards. Existing media cards at both ends of the link must be
replaced.
• The 4100 series Duplex Fiber Cards are not compatible with all modular network cards. Refer to Appendix A: Modular network card
compatibility for additional information.
• When you use fiber-optic cable, use SC connectors with long strain relief boots.
When servicing dual fiber-optic media cards, on retrofit jobs where multi-mode fibers with ST connectors are already installed, order service
kits 650-2013/650-2016 for 62.5/125um installations, or 650-2014/650-2015 for 50/125um installations.
