This OC-12 SFP supports 40km long reach link spans and operating at 622 Mbps is designed and tested to be 100% compatible in all Cisco switch, networking, and data center product lines and applications. This SFP supports extended temperature ranges and digital diagnostic functions (DDM) and is pre-configured and factory loaded with Cisco specific application code required for Cisco IOS, SMARTnet compliance, and the Cisco quality ID feature. Axiom transceivers are tested to perform functionally identical to the "original" transceiver.
