SPA-1XOC48POS/RPR 1 port OC48/STM16 POS/RPR Shared Port Adapters
Module
Products Specifications:
The Cisco® Interface Flexibility (I-Flex) design combines shared port
adapters (SPAs) and SPA interface processors (SIPs) to help enable
service prioritization for voice, video, and data services.
Enterprise and service provider customers can take advantage of
improved slot economics resulting from modular port adapters that
are interchangeable across Cisco routing platforms. The extensible
Cisco I-Flex design maximizes connectivity options and offers
superior service intelligence through programmable interface
processors that deliver line-rate performance. Cisco I-Flex
enhances speed-to-service revenue and provides a rich set of
quality of service (QoS) features for premium service delivery
while effectively reducing the overall cost of ownership. This data
sheet contains the specifications for the Cisco 1-, 2-, and 4-Port
OC-48c/STM-16c Packet over SONET/SDH (POS) and Resilient Packet
Ring (RPR) Shared Port Adapter (Cisco 1-, 2-, and 4-Port
OC-48c/STM-16c POS/RPR SPA; refer to Figure 1).
Product Overview
Figure 1. Cisco 2-Port OC-48c/STM-16c POS/RPR SPA with SFP Optics
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs are
available on high-end Cisco routing platforms and offers the
benefits of network scalability with lower initial costs and easy
upgrades. The SPAs continues the Cisco focus on investment
protection along with consistent feature support, broad interface
availability, and leading-edge technology. The SPAs allow different
interfaces (POS, ATM, etc.) to be deployed on the same carrier
card.
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS/RPR SPAs use Small
Form-Factor Pluggable (SFP) interfaces. SFP modules are available
in short-reach (2 km), intermediate-reach (15 km), and long-reach
(80 km) optics.
Applications
The Cisco 1-, 2-, and 4-Port OC-48c/STM-16c POS and RPR SPAs can be
used in multiple applications, including:
• Access and aggregation
• WAN uplinks
• Internet peering
These SPAs feature both packet over SONET/SDH for mesh fiber
networks (Figure 2) and Resilient Packet Ring for ring fiber
topologies (Figure 3). These SPAs comply with the IEEE 802.17 RPR
standard and also support the Spatial Reuse Protocol (SRP) for
compatibility with existing Dynamic Packet Transport/Resilient
Packet Ring (DPT/RPR) networks.

Key Features and Benefits
The Cisco SPA/SIP portfolio offers many advantages, including:
• Industry-leading modular, flexible, intelligent interface
processors
– Unmatched flexibility, allowing a combination of interface types
on the same interface processor for consistent services,
independent of access technology.
– Pioneering programmable interface processors that provide
flexibility for the service diversity required in next-generation
networks.
– Innovative design that provides intelligent delivery of services
without compromising on performance.
• Increased speed-to-service revenue
– The scalable, programmable Cisco architecture extended to 2.5
Gbps dramatically improves customer density, increasing potential
revenue per platform.
– Interface breadth (copper, channelized, POS, ATM, and Ethernet)
on a modular interface processor allows service providers to more
quickly roll out new services, ensuring all customers, large and
small, receive consistent, secure, and guaranteed services.
– High-density SFP interfaces are featured for high-port-count
applications with reach flexibility. Future optical technology
improvements can be adopted using existing SPAs.
• Significant investment protection
– Improved slot economics and increased density reduce capital
expenditures (CapEx).
– The ability to easily add new interfaces as they are needed
facilitates a "pay-as-you-grow" business model while still offering
a high-density solution.
– SPAs are shared across multiple platforms, and can be easily
moved from one to another, providing consistent feature support,
accelerated product delivery, and a significant reduction in
operating expenses (OpEx) through common sparing as service needs
change.
