Interface Specifications
The physical layer interface for the PA-POS-2OC3 is Optical Carrier-3 (OC-3c), the specification for
SONET STS-3c and SDH STM-1 transmission rates), and the PA-POS-2OC3 is designed to comply with
Packet-over-SONET specifications. The PA-POS-2OC3 provides two 155.520-Mbps Packet OC-3
network interfaces for all supported platforms.
Each PA-POS-2OC3 has two duplex LC-type receptacles that allow connection to single-mode or
multimode optical fiber. (For more information on the optical fiber cables you use with this port adapter,
