2-Port Channelized OC-12/DS0 SPA Interface Specifications
The framer processes incoming and outgoing SONET frames. The framer operates at OC-12c/STM-4 line
rates (622.08 Mbps). Packet data is transported with a user-configured encapsulation (such as Point-to-Point
Protocol [PPP]) and mapped into the STS-12c/STM-4 frame. The main operational mode of the framer is
OC-12, where each one of the 12 Paths can carry a DS3 and each DS3 can carry 28 DS1s.
The 2-Port Channelized OC-12/DS0 SPA interface is compliant with ANSI and Telco standards.
2-Port Channelized OC-12/DS0 SPA SFP Optical Transceiver Modules and
Cables
The 2-Port Channelized OC-12/DS0 SPA uses a small form-factor pluggable (SFP) optical transceiver module
installed in each port for SONET single-mode and multimode optical fiber connection. (See the following
figure.)
Cisco Systems qualifies the optics that are approved for use with its SPAs. The 2-Port Channelized OC-12/DS0
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
• LR SFP module (80 km)—SFP-OC12-LR2
