Cisco SPA-1XTENGE-XFP optical transport platforms Optical Transmission Module

The Cisco SPA-1XTENGE-XFP is a 1-port 10Gigabit Ethernet Shared Port Adapter XFP based optical transceiver module, used in Cisco optical transport platforms. Equipment of this generation is identified by the number on the label rather than by appearance, since units that look alike can differ in the detail that matters. Spares for equipment of this age are sourced from refurbished stock rather than from the manufacturer, which is why the part number and its markings carry the whole identification. A revision marking on a unit like this is part of its identity, not a production code: builds are qualified separately and are not freely interchangeable. Confirm the part number and any revision marking on the unit being replaced before ordering. Tech-Star (UK-based, shipped worldwide) supplies Cisco components for ongoing maintenance projects.
