Product Descriptions
This Cisco ONS-SI-2G-I1 compatible SFP industrial module is suitable for 2.5Gb/s serial optical data communications intermediate-reach application, such as SDH STM-16 S-16.1/SONET OC-48 IR-1/2GFC. It provides a 20km transmission distance over single-mode fiber at a nominal wavelength of 1310nm. It has been programmed and tested to work with a wide range of Cisco industrial switches and routers. It performs identically to Cisco part number ONS-SI-2G-I1, allowing it to be an ideally equivalent to original transceivers.
Applications
● SDH STM-16 and SONET OC-48 system
● 2X Fiber Channel
● Switch to Switch interface
● Switched backplane applications
● Router/Server interface
● Other optical transmission systems
