4-Port and 8-Port Fast Ethernet SPA Overview
Use a single-mode optical fiber that has a modal-field diameter of 8.7 ± 0.5 microns. (Nominal
diameter is approximately 10/125 microns.)
For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable
(see
Figure 3-9 ) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to
connect your router to a network or to connect two 1-Port Channelized STM-1/OC-3 SPA-equipped
routers back-to-back.
Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected
back-to-back without using an attenuator between the two of them.

4-Port and 8-Port Fast Ethernet SPA LEDs
The 4-Port and 8-Port Fast Ethernet SPA has two types of LEDs: an A/L LED for each port on the SPA,
and one STATUS LED, as shown in
Figure 3-10 .
