Note: It is strongly recommended to order this
device with original RAD SFPs installed. This will
ensure that prior to shipping, RAD has performed
comprehensive functional quality tests on the
entire assembled unit, including the SFP devices.
RAD cannot guarantee full compliance to product
specifications for units using non-RAD SFPs.
For detailed specifications of the SFP transceivers,
see the SFP Transceivers data sheet.
