Development of 100 Gb/s network infrastructure, even though nascent, is gathering momentum as a result of the progress made in the 100 Gb/s Ethernet and Optical Transport Network (OTN) standardization efforts. A 100 Gb/s test bed proposed by ESNet is expected to facilitate rapid data transfer between geographically dispersed clouds allowing scientists to use available computing resources regardless of location. Several commercial network operators such as Verizon and AT&T have also expressed their interest in deploying 40/100 Gb/s infrastructure in their core networks [2]. These forces have driven several network hardware manufacturers to intensify their focus on the 40/100 Gb/s network product development. The burgeoning interest in the deployment of such infrastructure necessitates the development of test and measurement equipment capable of operating at data rates of the order of 100 Gb/s. To this effect, efforts have been undertaken by several hardware vendors such as Spirent, Agilent, and Ixia to develop equipment that can assess the limitations and robustness of 40/100 Gb/s systems. For instance, the Spirent TestCenter HyperMetrics 40/100 Gb/s Ethernet Module has been designed to validate performance and scalability at layers 1-7. Acadia proposes to develop a 100 Gb/s low-cost and compact pattern generator/comparator module that can be widely deployed to perform compliance testing on the lower layers of the network. These test modules can be retained at deployed locations to monitor physical links on-demand i.e., even after completion of initial testing and verification. The system is also envisioned to seamlessly integrate with network performance measurement software such as perfSONAR. The proposed effort will focus on the development of a highly reliable physical layer testing setup enabling both short-haul and long-haul links to be checked for jitter, noise, and bit errors. The project will utilize a high-speed Field Programmable Gate Array (FPGA) generating a Pseudo Random Bit Sequence (PRBS) which is transmitted to the optical physical link under test. On the receive side, the incoming data is checked for any bit-errors using a comparator operating at line rate. Initially, Acadia intends to design the system to transmit/receive unframed traffic, i.e., without a Media Access Control (MAC) block to allow testing of transparent links.
