SpaceX launched 47 Starlink satellites from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. This was the ninth SpaceX launch of 2022. It was also the 11th flight for the Falcon 9 first stage booster supporting this mission, which previously launched GPS III-3, Turksat-5A, Transporter 2, and now eight Starlink missions. The booster […]
Micron Technology is sampling the first vertically-integrated 176-layer NAND data center solid-state drive. The Micron 7450 SSD with NVMe achieves latency at or below 2 ms for 99.9999% QoS in common, mixed, random workloads— driving up performance in databases such as Microsoft SQL Server, Oracle, MySQL, RocksDB, Cassandra and Aerospike, among others. Compared to SATA […]
Marvell introduced its Alaska A PAM4 DSP family for Active Electrical Cables (AECs) designed for data center interconnects by hyperscale customers.The new Alaska 400G/800G DSPs, fabricated in 6nm process, leverages Marvell’s PAM4 DSP technology to improve signal integrity in copper, short reach AECs to address emerging 100G/lane adoption in cloud data center interconnect architectures. The […]
Marvell is now sampling a 800Gbps or 8 x 100Gbps multimode platform for short-reach optical modules and Active Optical Cable (AOC) applications. The new 800G platform, which includes Marvell’s PAM4 DSP with a multimode transimpedance amplifier (TIA) and Driver, enables faster data center speeds scaling to 800Gbps, using conventional cost-effective vertical-cavity surface-emitting laser (VCSEL) technology […]
Molex is ramping production of its commercially available 400G ZR QSFP-DD pluggable coherent optical transceivers. Molex’s 400G ZR is among the first standards-based, pluggable coherent optical modules to be commercially available in volume. In addition, the 400G OpenZR+, which is slated for availability in Q2, extends reach from 120km to about 600km at low power […]
Qualcomm unveiled its FastConnect 7800 chipset offering Wi-Fi 7, Bluetooth connectivity and High Band Simultaneous Multi-link technology that leverages two Wi-Fi radios for four streams of high band connectivity in 5GHz and/or 6GHz bands. FastConnect 7800 supports all multi-link modes and with HBS Multi-Link, consumers can experience minimized latency and interference, jitter-free connections, and blazing […]
Vertical Systems Group announces that eight companies achieved a position on the year-end 2021 U.S. Wavelength Services LEADERBOARD (in rank order based on circuit share): Lumen, Zayo, Verizon, AT&T, Arelion (formerly Telia Carrier), Windstream, Crown Castle and Cox. This new benchmark measures U.S. market presence for wavelength providers selling retail and wholesale services. LEADERBOARD companies […]
IP Infusion provided its OcNOS white box network operating system (OS) to NTT for its development of uncompressed 8K120p video transmission technologies using the IOWN All-Photonics Network (APN). NTT recently announced its development of the world’s first-ever ultra-low latency video-transmission technology that supports uncompressed 8K120p video. Using a disaggregation configuration, it has succeeded in sending […]
Mitsubishi Electric will begin sampling its 50Gbps distributed-feedback (DFB) laser diode for 5G base stations. Key features Frequency-response characteristics are compatible with 4-level pulse-amplitude modulation (PAM4) for multilevel signal modulation, supporting transmission rates up to 50Gbps. Also, its industry-leading operating temperature range of -40°C to 90°C eliminates the need for any temperature-control unit, helping to […]
Ericsson demonstrated Dynamic Radio Resource Partitioning, a 5G Radio Access Network (RAN) Slicing solution that will enable six mobile network operators (MNOs) to deliver customized 5G services with guaranteed performance. Each MNO sharing DNB’s network has access to the full spectrum asset to achieve the best possible speed, while simultaneously ensuring the pooled spectrum is […]
EV Group (EVG), a leading supplier of wafer bonding and lithography equipment for the MEMS, nanotechnology and semiconductor markets, announced a collaboration with Teramount on implementing wafer-level optics. The collaboration will leverage EVG’s nanoimprint lithography (NIL) technology, expertise and services with Teramount’s PhotonicPlug technology. Under this collaboration, standard CMOS wafers that implement silicon photonics chips […]
AT&T is working with Nokia Bell Labs in testing distributed massive MIMO (DmMIMO) to significantly increases uplink capacity and speeds in 5G networks without requiring an overly complex solution. Specifically, Nokia is collaborating with AT&T on the validation of DmMIMO and testing the proof-of-concept technology in the AT&T labs. Bell Labs’s DmMIMO simulations have demonstrated […]
Nokia has added a Liquid Cooling option to its AirScale base station portfolio. The company calculates that liquid cooling can significantly reduce the energy required to cool a base station. Cooling system energy consumption can be reduced up to 90 percent and base station CO2 emissions up to 80 percent compared to traditional active air-cooling […]
