Client interface

As bandwidth demands continue to increase, network service providers are looking at 40G and 100G networks to accommodate the ongoing traffic surge. This new technology translates into greater speeds and a possible network infrastructure upgrade to compensate for various challenges that do not apply to slower networks, such as 10G.

Providing high-speed connectivity while protecting current network infrastructures requires broad expertise and wide-ranging testing to qualify the state of the fiber, perform fiber characterization and assess the integrity of data transmission over long-haul and ultra-long-haul networks.

EXFO's 40G/100G expertise encompasses network component and fiber testing throughout all the transmission network stages for commissioning, provisioning, turn-up and troubleshooting of networks. EXFO encompasses a range of 40G/100G testing solutions from the client interface to the line interface and the fiber network itself—to ensure seamless wireline and wireless network infrastructure upgrades.

Meeting 100G Testing Challenges—From the Lab to the Field

Line interface

Not only is the growing demand for 100G Ethernet network services making it increasingly complex, but it also introduces a new world of test challenges that require extensive expertise in several 100G network fields: line-coding modulation, transmitter analysis and advanced modulation schemes and impairments.

Today, network equipment manufacturers (NEMs) need thorough 100 Gbit/s testing solutions to confidently exploit these growing data rates, despite evolving standards and aggressive product development schedules. What is required is truly comprehensive testing that surpasses compliance to assess the limitations and robustness of their products, as well as to help them migrate from 40 Gbit/s and 100 Gbit/s to 400 Gbit/s and beyond—from the lab to the field.
