Renesas Electronics announced commercial availability of directly modulated laser (DML) diodes that deliver 25 Gbps x four wavelengths as the light source in 100 Gbps optical transceivers. The devices are designed for connecting 4.9G and 5G LTE base stations and between data center routers and servers. Renesas said its new RV2X6376A Series are the industry’s […]
Source Photonics introduced a range of 400G client transceivers including the 400G QSFP-DD FR8/LR8 module for data center applications and the 400G CFP8 FR8/LR8 module for telecom applications. Sampling is expected in Q2. The 400G QSFP-DD is designed to be compliant with the IEEE 802.3bs 400GBASE- LR8/FR8 and QSFP-DD MSA specifications for links up to […]
MACOM introduced a CWDM4 transmitter optical sub-assembly as a part of its L-PIC (Laser-integrated Silicon Photonic Integrated Circuit) solution for 100Gbps CWDM4. The combined solution integrates four high-performance 25Gbps CWDM wavelengths in a single silicon photonic integrated circuit (PIC) to communicate 100Gbps over duplex single mode fiber. MACOM said its L-PIC platform provides a highly […]
Molex introduced a portfolio of 100G and 400G products based on its 100G PAM-4 optical platform, including multi-Rate 25G/50G/100G PAM-4 DWDM QSFP28, 100G FR QSFP28, 400G DR4 and 400G FR4 QSFP-DD and OSFP. 100G PAM-4 platform-based product solutions include: 25G/50G/100G Multi-Rate PAM4 DWDM QSFP28: Supports 40×100 Gbps DWDM with a total of 4 Tbps per […]
Network densification is a key premise of 5G architecture. Once the rollouts of 5G networks begin in earnest, we should expect to see many more cell sites in urban areas across the world. How many more? That remains to see, but the count of small cells could be 10x of the number of macro base stations […]
Corning unveiled a new “RocketRibbon” extreme-density fiber cable for data center and carrier environments. RocketRibbon cables deliver up to 3,456 fibers in the same diameter as existing central and stranded tube cables. Corning is using a proprietary manufacturing process to create as many as 12 individually protected sub-units, each with 288 closely packed fibers. An […]
Cisco and Reliance Jio are collaborating in multi-access edge computing. The companies are developing a use case to optimize and enhance video experience over the network by building a mobile content delivery network (CDN). In this concept, the CDN is integrated into the mobile LTE network with edge caches in close proximity to the mobile […]
VPIphotonics announced the latest release of its VPIphotonics Design Suite for optical components and transmission systems. Version 9.9 comes with enhancements of the user interface and tools operation, as well as advances in simulation capabilities, such as new design and analysis tools for coherent M-QAM and direct-detection PAM-M systems, new and enhanced DSP and coding […]
Integrated Device Technology introduced a 64 Gbaud quad-channel linear optical modulator driver in a 14mm x 9.1mm Surface Mount Technology (SMT) package for 400G/600G coherent applications. The device can be used in line cards and CFP2 pluggable modules to bring next-generation 400G/600G products to the coherent market. The IDT GX66473 supports 64Gbaud 16QAM and 64QAM […]
ZTE has enhanced its ZXR10 T8000 core router with the addition of Bit Indexed Explicit Replication (BIER) technology — an industry first according to the company, and useful for balancing SDN backbone network traffic. ZTE describes BIER as a simplified multicast packet forwarding technology that does not require complex multicast protocols and multicast forwarding tables. […]
Netsparker, a start-up based in the U.K., raised $40 million in venture funding for its web application security scanning software. The funding round was led by Turn/River Capital, a San Francisco-based growth and private equity fund focused on enterprise software companies. Netsparker says its solution can identify security flaws in any type of website, web […]
A Soyuz rocket launched by Arianespace from the Guiana Space Center successfully carried four O3b satellites into Medium Earth Orbit (MEO). The new Ka-band satellites will join SES’s existing constellation of 12 MEO satellites, orbiting at approximately 8,000 km from Earth – four times closer to the planet than geostationary (GEO) satellites. Thales Alenia Space […]
Dr. Paul E. Jacobs will no longer serve as Executive Chairman of the Qualcomm Board of Directors. Jeffrey W. Henderson, an independent Qualcomm director since 2016, will serve as Non-Executive Chairman. Dr. Jacobs will continue to serve on the Qualcomm Board, but will no longer serve in an executive management capacity. Qualcomm said its Board […]
