Cisco's industry-standard Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. GBICs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant Gigabit interfaces on a port-by-port basis. As additional capabilities are developed, these modules make it easy to upgrade to the latest interface technology, maximizing investment protection.This GBIC module is designed for Cisco ONS 15454 SDH Multiservice Provisioning Platform.
