Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Data Sheet
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
Table 1 describes the features and benefits of the Cisco 2-Port OC-3/STM-1 POS Port Adapter.
Table 1. 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)
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
Greater flexibility in deployment and sparing; allows for mixed optics on a single port adapter
* Performance constrained only by processing engine
Modular Optics
The 2-Port OC-3/STM-1 POS Port Adapter offers support for two modular SFP optics. Figure 2 illustrates these ports.

SFP Optics
The 2-Port OC-3/STM-1 POS Port Adapter supports two ports of any of the following SFP optics: multimode (MM), single-mode fiber intermediate range (IR), and single-mode fiber long range (LR). Two different module types may be mixed in the same port adapter. The Product Ordering section of this document provides product part numbers for the SFPs used with the 2-Port OC-3/STM-1 POS Port Adapter.
