8-Port OC-3 STM-1/OC-12 STM-4 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
frame.
The 8-Port OC-3 STM-1/OC-12 STM-4 POS SPA interface complies with the following RFCs:

8-Port OC-3 STM-1/OC-12 STM-4 POS SPA Optical Transceiver Modules and
Cables
The 8-Port OC-3 STM-1/OC-12 STM-4 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
Cisco Systems qualifies the optics that are approved for use with its SPAs. The following OC-3 optical
transceiver modules are supported on the 8-Port OC-3 STM-1/OC-12 STM-4 POS SPA:
