Calibration is important in the measuring the effectiveness of fiber-optic cables. Fluke fellows Seymour Goldstein and Jeff Gust explain why.

Ever increasing data demands push optical networks to transport data at faster and faster rates. Modulation and baud rate affect the distances that optical signals can travel.

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.

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.

Modulation and polarization multiply data capacity on optical networks. In the beginning of optical networks, all optical signals were based on a simple mechanism known as on-off keying (OOK). In simple terms, this mechanism works by switching a light on and off to transmit data. OOK is a wider definition for representing whether data is…

ZNrun software from Rohde & Schwarz automates Ethernet cable testing in combination with a VNA and switch.

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.

The Lightpass-EOB 100G from I-Pex shortens PCB traces, thus improving BER.

Corning’s Roshene McCool explains how the SMF-28 Contour fiber reduces light losses, installation costs, and operating costs in fiber connections for 5G, computing, and datacenters.

The GN2255 clock-data recovery chip from Semtech cleans signals in 50 Gbps PAM4 data streams and integrates an optical laser driver.
