1-Port Channelized OC-12/STM-4 SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs Figure 3-47 SFP Optics Module 127158 The SFP optical transceiver modules used with the 1-Port Channelized OC-12/STM-4 SPA provide the following optical fiber options: • Multimode-622-Mbps, OC-12/STM-4 optical fiber (SONET STS-12 or SDH STM-4) Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns. • Single-mode-622-Mbps, OC-12/STM-4 optical fiber (SONET STS-12 or SDH STM-4) 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 3-48) 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 OC-12/STM-4 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.

1-Port Channelized OC-12/STM-4 SPA Overview
Figure 3-47
SFP Optics Module
The SFP optical transceiver modules used with the 1-Port Channelized OC-12/STM-4 SPA provide the
following optical fiber options:
Multimode—622-Mbps, OC-12/STM-4 optical fiber (SONET STS-12 or SDH STM-4)
Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.
Single-mode—622-Mbps, OC-12/STM-4 optical fiber (SONET STS-12 or SDH STM-4)
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 3-48
) 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 OC-12/STM-4 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.
