Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs 1-Port Clear Channel OC-12 ATM SPA Overview 1-Port Clear Channel OC-12 ATM SPA Interface Specifications The physical layer interface for the 1-Port Clear Channel OC-12 ATM SPA is Optical Carrier-12 (OC-12), and the 1-Port Clear Channel OC-12 ATM SPA is designed to comply with ATM specifications. The 1-Port Clear Channel OC-12 ATM SPA provides one 622.08 Mbps OC-12 network interface for all supported platforms. The single SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to single-mode or multimode optical fiber. 1-Port Clear Channel OC-12 ATM SPA Cables and Connectors The 1-Port Clear Channel OC-12 ATM SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber connection (see Figure 3-5). The 1-Port Clear Channel OC-12 ATM 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 The SR, IR, and LR1 transceivers provide a full-duplex 622.08-Mbps, laser-based SONET/SDHcompliant interface with an average wavelength of 1310 nm. The LR2 transceivers provide a full-duplex, 622.08-Mbps, laser-based SONET/SDH-compliant interface with an average wavelength of 1530 nm. The multimode transceiver provides a full-duplex, 622.08-Mbps, LED-based SONET/SDH-compliant interface with an average wavelength of 1325 nm. Figure 3-5 SFP Optics Module 127158 OL-14126-12 The 1-Port Clear Channel OC-12 ATM SPA provides 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) Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide 3-11
