4-Port and 8-Port Fast Ethernet SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs 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 3-6) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).
