*Examples made using 4190 9010 Bi-Directional Couplers
Notes for Table 12 and Table 13:
1. Cable specifications are for 50 or 62.5 micron core with 125 micron cladding, multi-mode graded index fiber. Wavelength = 850
nm.
2. MIFL = Maximum Individual Fiber Loss. Numbers shown are for example reference only, refer to specific cable for exact
specification.
3. Maximum cable length is determined by distance listed or by reaching budget value, whichever is shorter. Maximum distances
listed for dual fiber cable are shorter than would be calculated. Budget using 4190-9010 Bi-Directional Coupler is the same with
either size cable because the coupler input cables are 62.5/125 fiber allowing launch power to be the same.
Figure 51 shows coupler wiring.
7.5.7 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 21 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 for 62.5/125um installations, or 650-2014 for 50/125um installations.
