Product Description
The 3Com 3C13881 is a high-performance interface card designed to bring robust optical networking capabilities to 3Com's compatible network devices. This card features a single OC3 POS (Packet over SONET/SDH) port, which operates at a data rate of 155 Mbps. Packet over SONET/SDH is a standard protocol used for transmitting IP packets over SONET or SDH optical networks, providing a reliable and efficient method for high-speed data transport over long distances. As a Flexible Interface Card (FIC), the 3C13881 is designed for easy integration into 3Com switches and routers, allowing for modular expansion of network capacity. The OC3 speed is a foundational rate in optical networking, often used in metropolitan area networks (MANs), wide area networks (WANs), and as a backbone connection within large enterprise networks or for service providers connecting to their infrastructure. The primary advantage of using POS technology is its inherent reliability and resilience, derived from the SONET/SDH standards. These standards include features like automatic protection switching, which can reroute traffic around fiber cuts or equipment failures within milliseconds, ensuring high availability. The 3C13881 card enables network designers to leverage these benefits for critical data transport, making it suitable for applications demanding consistent performance and uptime, such as voice, video, and high-volume data traffic.
