Cisco Catalyst 4500 Series 48-Port 100BASE-LX10 Fast Ethernet Line Card

Forty-eight 100BASE-LX10 Fast Ethernet ports for single-mode fiber provide high-density connectivity for both residential and small business customers over distances up to 10 km. Fast Ethernet over single-mode fiber offers an attractive choice of cost and future performance-the same access fiber infrastructure can be gigabit-enabled by upgrading the switching equipment. In addition, the line card supports the emerging standard for Fast Ethernet over single-mode fiber, simplifying new infrastructure designs through interoperability.

Cisco Catalyst 4500 Series EFM line cards are also appropriate for manufacturing facilities, transportation monitoring, and fiber-to-the-desktop applications. Ethernet over fiber enables operation in noisy electromagnetic environments, physical security, and longer reaches with the same, well-understood Ethernet transport.
