1-Port OC-12c/STM-4 POS SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs • RFC 1213, Management Information Base (MIB) for Network Management of TCP/IP-Based Internets:MIB II 1-Port OC-12c/STM-4 POS SPA SFP Optical Transceiver Modules and Cables The 1-Port OC-12c/STM-4 POS SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in the port for SONET and SDH single-mode and multimode optical fiber connection (see Figure 3-30). Cisco qualifies the optics that are approved for use with its SPAs. The 1-Port OC-12c/STM-4 POS SPA supports the following types of optical transceiver modules: • Multimode (MM) SFP module-SFP-OC12-MM • Short-reach (SR) SFP module-SFP-OC12-SR • Intermediate-reach (IR) SFP module (15 km)-SFP-OC12-IR1 • Long-reach (LR) SFP module (40 km)-SFP-OC12-LR1 • Long-reach (LR) SFP module (80 km)-SFP-OC12-LR2 Figure 3-30 SFP Optics Module 127158 The SFP optical transceiver modules used with the 1-Port OC-12c/STM-4 POS SPA provide the following optical fiber options: • Multimode-622.08-Mbps, OC-12 optical fiber (SONET STS-12c or SDH STM-4) Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns. • Single-mode-622.08-Mbps, OC-12 optical fiber (SONET STS-12c 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 3-31) 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 OC-12c/STM-4 POS 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. 3-46 Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide OL-14126-12
