8-Port OC-12c/STM-4 Multirate POS SPA Overview
8-Port OC-12c/STM-4 Multirate POS SPA Interface Specifications
The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-3 line
rates (155.52 Mbps) and OC-12 line rates (622.08 Mbps). Packet data is transported with a
user-configured encapsulation (such as Point-to-Point Protocol [PPP]) and is mapped into the Layer 2
fr
ame.
The 8-Port OC-12c/STM-4 Multirate POS SPA i
nterface complies with the following RFCs:
• RFC 1662, PPP in HDLC-like Framing
• RFC 2427, Multiprotocol Interconnect over Frame Relay
• RFC 2615, PPP over SONET/SDH
8-Port OC-12c/STM-4 Multirate POS SPA Optical Transceiver Modules and
Cables
The 8-Port OC-12c/STM-4 Multirate POS 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
connections (see Figure 3-12).
Cisco Systems qualifies the optics that are approved fo
r use with its SPAs. The following OC-3 optical
transceiver modules are supported on the 8-Port OC-12c/STM-4 Multirate POS SPA:
• Multimode (MM) SFP module—SFP-OC3-MM
• Short-reach (SR) SFP module—SFP-OC3-SR
• Intermediate-reach (IR) SFP module (15 km)—SFP-OC3-IR1
• Long-reach (LR) SFP module (40 km)—SFP-OC3-LR1
• Long-reach (LR) SFP module (80 km)—SFP-OC3-LR2
The following OC-12 optical transcei
ver modules are supported on the 8-Port OC-12c/STM-4 Multirate
POS SPA:
• 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
