EE World visited Effect Photonics’ Massachusetts office for a video look at how its optical communications products adapt to changing conditions in telecom and data networks. Maynard, Mass. — Data from 5G fronthaul through core networks and datacenters move quickest when transported over optical fibers. Effect Photonics, a company based in the Netherlands, recently opened…
Transimpedance amp could enable 100 Gb/sec PON
The upstream linear burst-mode transimpedance amplifier is the first to support 50 Gb/sec NRZ and 100 Gb/sec PAM4. They could drastically increase internet connection speeds and 5G infrastructure.
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.
High-speed data challenges physical-layer optics
Calibration is important in the measuring the effectiveness of fiber-optic cables. Fluke fellows Seymour Goldstein and Jeff Gust explain why.
Optical networks move to metro 800G and long haul 400G
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.
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.
How coherent optics increase data rates
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…
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.
