2-Port and 4-Port OC-3c/STM-1 POS SPA Interface Specifications

The framer processes incoming and outgoing SONET or SDH frames. The framer operates at
OC-3c/STM-1 line rates (155.52 Mbps).
Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]),
and is mapped into the STS-3c/STM-1 frame.
The 2-Port and 4-Port OC-3c/STM-1 POS SPA interface complies with the following RFCs:

2-Port and 4-Port OC-3c/STM-1 POS SPA Optical Transceiver Modules and
Cables
The 2-Port and 4-Port OC-3c/STM-1 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
connection (see
Cisco qualifies the optics that are approved for use with its SPAs. The 2-Port and 4-Port OC-3c/STM-1
POS SPA supports the following types of optical transceiver modules:
