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,

see the “Cables and Connectors” section on page 1-6.)
