Security Offloads and Fiber-Optic Throughput
Designed for Windows, Linux, and NetWare environments, this low-profile version of the 3Com® 100 Secure Fiber-FX NIC hardens at-risk systems without impacting performance. It combines an embedded security processor with the outstanding signal quality of fiber-optic cabling. This innovative 100BASE-FX connection offloads encryption, authentication, and other cycle-intensive tasks from the host CPU-resulting in optimal system and application response. The lack of electrical resistance makes fiber-cabled infrastructures particularly useful for reducing line interference or "noise", extending connection distances over 100 meters, or delivering the highest-quality voice and video transmissions. Intelligent management and server features help improve network performance, reduce administration time, and lower support costs. |

Works with fiber-optic cabling to extend operating distances, lower electrical interference, and resist packet sniffing
Secures sensitive data at wire speeds—with DES/3DES encryption, MD5 and SHA-1 hashing, RFC 2402 authentication, and up to 75 Security Associations
Hardware-enforced security features meet FIPS 140-2 criteria; NIST approval pending
Supports larger packets—segments TCP frames for the Ethernet MAC and adds TCP sequence numbers to each packet
Uses flow control to reduce lost packets and retransmissions for more efficient data transfer between the NIC and switch
Responds to router-based management requests from sleep mode to help resolve IP address-aging issues
Includes 3Com Connection Assistant, a web-based interface that provides self- and assisted-service for end users and support technicians
Includes 3Com Managed PC Boot Agent for pre-OS management, including installation, recovery, and network boot
