Re-use old fiber for 100G?

Cisco paper explains how IPoDWDM protocol re-uses older fiber for 100G systems.

A recent technical white paper from Cisco emphasizes how the scale of service providers’ networks is increasing dramatically and subsequently driving companies' costs higher. In a world where network scale must increase while total cost of ownership is minimized, the company contends that its IPoDWDM technology for 100 Gigabit Ethernet reduces cost by eliminating equipment redundancies found in separate router and DWDM system designs for 100G.

The paper explains how Cisco's coherent detection technology lowers costs by enabling longer optical reach without regeneration or specialized amplification. "It also reduces cost by allowing more re-use of older fiber," notes the research analysis.
