Where do cost savings come from?

Infinera's GMPLS implementation is used in some of the largest GMPLS-powered networks in the world. From this experience of a "full function" GMPLS implementation over a Digital Optical Network architecture we've been able to derive some significant examples of operational cost savings.

Operation/Task All-optical network GMPLS-powered DON Installation, commissioning and turn-up (700km circuit) 2 weeks 3 days 10G/2.5G wavelength turn-up 1 to 3 days <1 day Conversion of pass-through site to add/drop 3 to 4 days 2 hours Sub-lambda grooming efficiency Low High

The DON also offers a number of other operational cost savings because the network operator is able to return to digital operations. These include the fact that the Infinera DTN can offer digital loopback for error checking and diagnostics, and this leads to much more rapid fault isolation. Our implementation of ITU-T G.709 allows pre-and post-Forward Error Check (FEC) bit error rates to be monitored at every switching point in the network.

This table also shows a vital feature of the GMPLS-powered DON—the ability to deliver services much more rapidly than a conventional, all-optical network. In today's highly competitive business environment, business is awarded to the first service provider to be able to deliver a given service at a given price. Prices are set by market forces, but your ability to deliver service in a given timescale depend on the efficiency of your operational procedures, and the flexibility and efficiency of your network architecture.
