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.
CDR chip supports 50 Gbps data streams
The GN2255 clock-data recovery chip from Semtech cleans signals in 50 Gbps PAM4 data streams and integrates an optical laser driver.
Portable 5G/Ethernet tester takes to the field
The MT1040A from Anritsu analyzes traffic on 5G, Ethernet and other optical and electrical networks.
Load Testing: An important function in Open RAN deployment
Video: VIAVI Solutions has added load testing to its 5G network test equipment, but load testing is just one part of interoperability and compliance testing of the open RAN. 5GTW interviewed VIAVI’s Owen O’Donnell to learn about testing Open RAN.
Video: OIF launches 224 Gbps project preview
Engineers will once again roll up their sleeves and figure out how to increase data rates because “we need fatter channels.”
Grandmaster clock gets enhancements
Microchip’s TimeProvider 4100 adds virtual Precision Reference Time Clock support, transferring time throughout a network. With IEEE 1588 moving into 5G networks, having a grandmaster clock becomes essential for the protocol to distribute time around a network. Microchip’s IEEE 1588v2 grandmaster clock, TimeProvider 4100 Release 2.1, adds features such as virtual Precision Reference Time Clock…
5G fronthaul networks add flexibility
Flexibility in network control and distribution has created the need for separating the functions between wireless and wired network equipment. To deliver on the promise of 5G, which sometimes seems like everything to everyone, network operators will need to augment their existing network architectures, addressing some flexibility brought into existence with the new 5G technologies…
