The Optical Fiber Communications Conference (OFC) returned once again to provide a crucial platform for companies of the industry from around the globe. Taken place this past week, March 5th to 9th in San Diego, the annual exhibition and conference presented up-to-date techniques, materials, technologies, and applications in fiber optic technology. Below you will find…
What is a SmartNIC and its underlying architecture?
Learn the basics about SmartNICs, their design, and why they’ll be a crucial element in future networks.
Inject disturbances into power rails with a “cool” probe
The P2124 from Picotest lets you inject modulation signals onto your board’s power rails for noise immunity testing.
RF over fiber: overcoming an inherent transmission-line problem, part 2
Learn the basics of how to use RF over fiber. You have many options.
RF over fiber: overcoming an inherent transmission-line problem, part 1
Optical fiber can carry analog RF signals from antenna to receiver with far less loss than coaxial cables.
How PAM4 moves bits through networks
In an audio interview, Semtech’s Raza Khan explains why 5G networks use the four-level modulation to transport baseband data, starting at the radio.
Coherent optics move toward interoperability
At OFC 2022, OIF demonstrated products from several companies communicating with each other based on a standard for interoperable coherent optics. Other demonstrations included a 112 Gb/sec electrical link, flexible Ethernet, co-packaging, and a 224 Gb/sec technology proposal.
Software automates high-speed Ethernet cable testing
ZNrun software from Rohde & Schwarz automates Ethernet cable testing in combination with a VNA and switch.
BERT tests serial data streams to 120 Gbaud
The M8050A BERT from Keysight technologies let’s you test electrical interfaces for digital data streams for emerging data rates of 800 Gb/sec and 1.6 Tb/sec.
Optical module carries signals to the board’s edge
The Lightpass-EOB 100G from I-Pex shortens PCB traces, thus improving BER.
