Buying Many Products
It is a technique of buying multiple fixed income products, each with a different maturity.
Reinvesting
When a product matures, monies can be reinvested in a new product with highest yield in the available time horizon.
Maturing Principal
In a rising interest rate scenario, the maturing principal can be reinvested at higher rates.
Money Locked
By staggering maturity dates, investors avoid getting locked into a single interest rate.

FD Ladder
