Cisco 2-Port OC-3/STM-1 Packet-over-SONET Port Adapter
To meet the continual need for increased router features and performance, Cisco Systems
®
introduces its newest packet-
over-SONET (POS) port adapter, the Cisco
®
2-Port OC-3/STM-1 POS Port Adapter. The 2-Port OC-3/STM-1 POS Port
Adapter is ideal for service providers or large enterprises that need to deploy multiple ports of OC-3/STM-1 connectivity
or a single OC-3/STM-1 port with redundancy and failover support.
The 2-Port OC-3/STM-1 POS Port Adapter (Figure 1) combines superior performance and an innovative design to provide the following
benefits:
∑
Dual-port, line-rate performance
∑
Automatic protection switching (APS) failover between ports
∑
Modular, pluggable optics (Three types are available: multimode fiber, short range [MM]; single-mode fiber, intermediate range [SMIR];
and single-mode fiber, long range [SMLR])

Features and Benefits of the Cisco 2-Port OC-3/STM-1 POS Port Adapter
Features
Benefits
Dual port connectivity
Greater per-slot density for Cisco platforms using port adapter technology (for example, on the Cisco
7200 or Cisco 7400 Series)
7200 or Cisco 7400 Series)
Performance
Depending on processing engine, provides line-rate bidirectional performance across both ports*
APS
Provides failover protection between POS ports and/or port adapters
Modular Small Form-Factor
Pluggable (SFP) optics
Pluggable (SFP) optics
Greater flexibility in deployment and sparing; allows for mixed optics on a single port adapter
* Performance constrained only by processing engine
