Infinera Measures "Network EQ" for Optical Transport

Infinera introduced a "Network EQ" framework for comparing next-generation optical transport network architectures, enabling network operators to evaluate the ripple effect of architectural decisions on the total cost of ownership (TCO). As a relative measure of optical transport network efficiency, EQ compares the impact of capital expenses (CapEx) and operating expenses (OpEx) of architectural alternatives over time. The results show that some operators may be able to reduce TCO by up to 70% with an optimal architectural approach.

Infinera is providing two applications for calculating this transport network EQ: the EQ Estimator and EQ Power Analyzer. Additionally, Infinera is introducing EQ Engagement which provides select customer engagements with Infinera consultants for network specific TCO analysis.

Infinera said results from its testing show that some operators may be able to reduce TCO by up to 70% with an optimal network architectural approach.

"In conversations with service providers around the world, we are seeing increased focus on driving efficiencies from the transport network to the bottom line of their income statement," said Tom Fallon, Infinera CEO. "The EQ framework simplifies the analysis of transport network architectures as they impact total cost of ownership, providing operators a quick way to recognize opportunities to improve network efficiency for their bottom line."
